Topic Overview
Is this topic for you?
This topic is about
prostate cancer that has spread or come back after treatment. For information
on early cancer of the prostate gland, see the topic
Prostate Cancer.
What is prostate cancer?
Prostate cancer is a group of cells that grows faster than normal in a
man's prostate gland. It can spread into other areas and kill normal
tissue.
The
prostate gland sits just below a man's bladder. It makes part of the fluid for
semen. In young men, the prostate is about the size of
a walnut. It usually grows larger as you grow older.
The cancer
may be one of these types:
-
Locally advanced prostate cancer
. This is cancer that
has grown through the outer rim of the prostate and into nearby tissue.
-
Metastatic prostate cancer
. This is cancer that has
spread, or metastasized, to the
lymph nodes or other parts of the body.
-
Recurrent prostate cancer
. This is cancer that has
come back after it was treated. The cancer can come back in the prostate, near
the prostate, or in another part of the body. If it comes back in another part
of the body—often the bones—it is still called prostate cancer, because it
started in the prostate.
What causes prostate cancer?
Experts don't know what causes prostate cancer. But they believe that
getting older and having a family history of prostate cancer raise your chance
of getting it.
What are the symptoms?
Sometimes there are no symptoms of either locally
advanced or metastatic prostate cancer.
When they do appear,
symptoms of locally advanced prostate cancer include:
- Waking up many times during the night to urinate.
- Having trouble starting your urine stream, having a
weaker-than-normal stream, or not being able to urinate at all.
- Having pain or a burning feeling when you urinate.
- Having blood in your urine.
- Having a deep pain or stiffness in your lower back, upper
thighs, or hips.
Symptoms of metastatic prostate cancer may include:
- Bone pain.
- Weight loss.
- Swelling in your legs and feet.
How is prostate cancer diagnosed?
Your doctor will do a
digital rectal exam, in which he or she puts a gloved,
lubricated finger in your rectum to feel your prostate. You may also have a
blood test called a
prostate-specific antigen (PSA) test. These tests will
help find out if you have prostate cancer or if your prostate cancer has come
back.
Your doctor also may do a
biopsy. In this test, your doctor takes a sample of
tissue from your prostate gland or from the area where the cancer may have
spread and sends the sample to a lab for testing. A biopsy is the only way to
know for sure that you have prostate cancer.
If you have had
prostate cancer before, your doctor may also order a
bone scan,
CT scan, or
MRI to see if it has come back or spread.
Finding out that you have cancer can be scary. It may help to talk with
your doctor or with other people who have had cancer. Your local American
Cancer Society chapter can help you find a support group.
How is it treated?
Choosing treatment for
prostate cancer can be confusing. Your choices depend on your overall health,
how fast the cancer is growing, and how far it has spread.
Locally advanced prostate cancer may be treated with surgery, radiation
therapy, or hormone therapy.
Treatment of metastatic cancer
focuses on slowing the spread of the cancer and relieving symptoms, such as
bone pain. It also can help you feel better and live longer. Treatment may
include hormone therapy, radiation therapy, or chemotherapy.

Cause
The exact cause of
prostate cancer is not known, but experts believe your
age and family history may have something to do with your chances of getting
the disease. Prostate cancer is very common and is an older man's disease. Most
men who get it are older than 65.
Symptoms
Prostate cancer may not cause noticeable
symptoms. Possible symptoms of
locally advanced prostate cancer are:
- Urinary problems, such as:
- Not being able to urinate at all.
- Having a hard time starting or stopping the flow of urine.
- Having to urinate often, especially at night.
- Having pain or burning during urination.
- Difficulty having an erection.
- Blood in your urine or semen.
- Deep and frequent pain in your lower back, belly, hip, or pelvis.
These symptoms also may be caused by:
-
Benign prostatic hyperplasia (BPH)
, which is an
enlarged prostate. This is very common in older men. The prostate usually grows
larger with age. When it gets large enough, it can press against the urethra
and cause urination problems.
-
Prostatitis
, an infection in the prostate.
-
Urinary tract infection
, an infection in any of the
organs and tubes that process and carry urine out of the body.
Symptoms that may indicate the cancer has spread to other
parts of the body, or metastasized, include:
- Weight loss.
- Bone pain.
- Swelling in the legs and feet.
What Happens
Prostate cancer is a common cancer affecting older
men. About 17 out of 100 men living in the United States will get prostate cancer. Out of these 17 men, 3
will die of prostate cancer. This means that 97 out of 100 men will die from something other than prostate
cancer.1
It usually is a very
slow-growing cancer that takes years to grow large enough to cause any
symptoms. In some men, it never does cause problems. Sometimes, though, it
grows quickly and may cause complications or death.
When prostate
cancer grows large enough, it begins to fill the prostate and often can be felt
by your doctor during a
digital rectal exam. As it continues to grow, it
breaks through the outer rim of the prostate and into nearby tissues, such as
the
seminal vesicles. At this point, the disease is called
locally advanced prostate cancer.
Locally advanced prostate cancer is usually not curable. But there are treatments that can help you live longer and feel better. Most men live up to 5 years after this diagnosis, but some men may
live longer.2
After the
cancer has broken through the prostate, it may move into nearby lymph nodes.
From the lymph node system, the cancer can spread to other areas of the body.
Most often, prostate cancer spreads to the bones. It also may spread to the
lungs or other organs. When it has spread to the
lymph nodes, the disease is called metastatic prostate cancer.
Metastatic prostate cancer is not curable. But a
number of treatments are available to help you live longer and make you feel
better. Most men live 1 to 3 years after this diagnosis, but some men may
live many years longer.2
What Increases Your Risk
A risk is anything that makes
you more likely to get a particular disease. Being older than 50 is the main
risk for
prostate cancer. At least 6 out of 10 new prostate
cancers are diagnosed in men who are 65 and older.3
Your chances of getting the disease are higher
if other men in your family have had it. Your risk is doubled if your father or
brother developed prostate cancer. Your risk also depends on the age at which your relative was diagnosed. Most
men who get prostate cancer have no family history of the disease.
Race and prostate cancer
African-American
men and Jamaican men of African descent have a greater chance of developing the
kind of prostate cancer that grows and spreads. Researchers are not sure why
there is a difference in disease and death rates among different races. Some
experts think there may be a genetic link.4
When To Call a Doctor
Call your doctor immediately if you:
- Are completely unable to urinate.
- Have painful urination and a fever higher than
100 F (37.78 C), chills, or
body aches.
- Have blood or pus in your urine or semen.
Call your doctor to schedule an appointment if you have
unexplained:
- Weight loss.
- Dull, aching pain in your lower back, pelvis, or hips.
- Swollen
lymph nodes in the groin area. These nodes are usually
not tender.
Active surveillance
Active surveillance (watchful waiting) may mean not trying to get rid of the cancer. If an older man has serious health problems and isn't
expected to live long, he may not be able to handle treatments or even want to have treatments except those
needed to keep him comfortable (palliative care).
But active surveillance sometimes means a man will be watched closely by his doctor and have regular checkups.
If the cancer starts to grow more quickly, he will have other treatment.
Active surveillance may not be a
choice when
prostate cancer has spread.
Sometimes men who have PSA levels that are rising slowly after having treatment may not start hormone treatments right away but be monitored with active surveillance.
Who to see
Doctors who can treat locally advanced and metastatic
prostate cancer include:
To prepare for your appointment, see the topic Making the Most of Your Appointment.
Exams and Tests
Locally advanced
and
metastatic prostate cancer are diagnosed through
physical exams and tests, including:
- A
digital rectal exam, in which the doctor inserts a
gloved finger into your rectum to feel your prostate gland. Some prostate
tumors can be found this way.
- A
PSA test to measure the levels of prostate-specific
antigen (PSA) in your blood. A higher level of PSA may indicate an enlargement,
infection, or cancer of the prostate. A rising PSA level after treatment for
prostate cancer can mean your cancer has come back.
- A
urine test, in which some of your urine is sent to a
lab and checked for blood or infection. Prostate cancer can cause blood in the
urine.
- A
prostate biopsy, in which tissue is taken from your
prostate and examined under a microscope. The other exams and tests
can give clues that you may have prostate cancer, but only a prostate biopsy can
tell for sure.
If you have had prostate cancer before, one or more tests
will help your doctor see if your cancer has come back or spread. These may
include:
- Blood tests. Different types of blood tests are used to see
whether cancer has spread to your bones or liver.
- A
bone scan. Radioactive material that shows up on
X-rays is injected into your arm. An X-ray camera passes over your body, taking
pictures as the radioactive material moves into your bones. Areas of bone
damage show up in the pictures. Prostate cancer that has spread to the bones
can cause this kind of damage.
- A
CT scan. A CT scanner directs a series of X-ray pulses
through your body. Each X-ray pulse lasts only a fraction of a second and
represents a “slice” of the organ or area being studied.
- An
MRI. An MRI uses a strong magnetic field to make
pictures of the prostate. This can show tissue damage or disease, such as
infection or a tumor.
- ProstaScint scan. Radioactive material that is absorbed by
prostate cancer cells and shows up on X-rays is injected into your vein. Four
days after the injection, your body is scanned with a special camera, and lymph
nodes and other areas that have been invaded by prostate cancer cells show up
on the scanning image.
Follow-up checkups
If
you have been treated for prostate cancer in the past, you've probably been
having regular checkups that include
PSA tests to check for any signs that the cancer has
come back or has spread to other parts of your body. Your doctor will watch for
any increases in your PSA level and the speed with which any increases occur. A
higher PSA does not necessarily mean your cancer has come back. But it may mean that you need further tests, such as a prostate biopsy, bone scan, CT scan, or
MRI.
Treatment Overview
Choosing treatment for
prostate cancer can be confusing. Any treatment
probably will cause serious side effects. It's important to learn all you can
about your choices and talk to your doctor about them.
Your treatment options will depend on:
- What kind of cancer cells you have. This is called the
grade or Gleason score of your cancer. Some prostate
cancer cells grow more quickly than others.
- Your age.
- Any serious health problems you might have, including urinary,
bowel, or sexual function problems.
- Your
PSA level.
Treatment for
locally advanced or
metastatic prostate cancer may include hormone
therapy, surgery, radiation therapy, and chemotherapy. You may
want to talk with your doctor about entering a
clinical trial of new cancer treatment options.
Some treatments being studied in clinical trials for advanced prostate cancer include ultrasound-guided cryosurgery, proton beam radiation, mixed beam radiation, and high-intensity-focused ultrasound (HIFU). For metastatic prostate cancer, treatments in clinical trials include new forms of chemotherapy and immunotherapy, including vaccines.
Prostate cancer and its treatment may cause nausea, pain, or other side
effects. You can manage some side effects
at home. If you experience
nausea, wait for 1 hour after vomiting has stopped and
then sip a
rehydration drink to restore lost fluids and
nutrients. Your doctor also may prescribe
medicines to control nausea and vomiting.
Constipation and
diarrhea may be eased if you drink enough fluids.
Pain from cancer that has spread to the bones can be managed. If pain becomes a problem, talk to your doctor about seeing a pain management specialist. For tips
on handling pain, see:
-
Cancer: Controlling Cancer Pain.
For more information, see the topic
Cancer Pain.
Localized prostate cancer is
cancer that has not spread outside the prostate. For more
information on treatment of localized prostate cancer, see the topic
Prostate Cancer.
Treatment for locally advanced prostate cancer
Prostate cancer
that has spread to
tissue around the prostate may be treated with:
-
Radiation therapy
. This treatment uses high-energy
X-rays or protons to destroy the cancer. Radiation treatments, both external
and internal radiation, have been improved with newer technologies, so there
are fewer side effects and complications than in the past. Radiation therapy
usually is combined with hormone therapy.
- External radiation. Also called
external beam radiotherapy, or EBRT, radiation therapy uses high-energy rays,
such as X-rays, to destroy the cancer. It is usually given in multiple doses
over several weeks. For men with locally advanced cancers, ERBT may be given
along with brachytherapy. Radiation destroys tissue, so it may damage the
nerves along the side of the prostate that affect your ability to have an
erection. If you already have bowel problems, external radiation may cause your
symptoms to get worse. The two most common forms of external radiation are
listed below:
- Conformal radiotherapy (3D-CRT)
uses a three-dimensional planning system to target a strong dose of radiation
to the prostate cancer. This helps to protect healthy tissue from
radiation.
- Intensity modulated radiation therapy (IMRT) uses newer 3D-CRT technology to target the cancer.
-
Surgery.
-
Radical prostatectomy. This operation
takes out your prostate gland and the cancer in and around it. After surgery, men usually are started on hormone therapy.
-
Transurethral resection of the prostate (TURP)
. This surgery can help relieve bladder problems, because it
removes part of the tumor that may be blocking the
urethra, the tube that carries urine from your bladder
through your penis. The procedure is done under
general anesthesia. This can keep the tumor from
growing for a while. But TURP does not take out the whole tumor.
-
Hormone therapy, also called androgen deprivation therapy (ADT). Prostate cancer needs male
hormones (testosterone) in order to survive. Hormone therapy
decreases the amount of testosterone and other male hormones in your body. This
often causes tumors to shrink. Shrinking the tumors can ease severe bone pain
caused by the spread of cancer to the bones. Hormone therapy usually is
combined with radiation therapy. The most common methods are:
- LH-RH agonists and GnRH agonists. These drugs, such as
goserelin (Zoladex), leuprolide (Lupron), and triptorelin (Trelstar),
stop the body from making testosterone.
- GnRH antagonists. These drugs stop the body from making testosterone. They work right away and avoid the flare caused by GnRH agonists that can make symptoms worse for several weeks. One GnRH antagonist is degarelix (Firmagon).
- Antiandrogens. These drugs, such as bicalutamide
(Casodex), often are used along with LH-RH agonists. Antiandrogens help block
the body's supply of testosterone.
- Orchiectomy. This is surgery to remove
the testicles, which produce more than 90% of the body's male hormones (androgens), including testosterone.
In some cases, men will have radiation therapy after a
prostatectomy, especially if the tumor could not be completely removed by
surgery.
Some men choose to start hormone therapy only after they
have symptoms. But many doctors recommend starting hormone therapy right away
if cancer is found in the
lymph nodes during surgery to remove the prostate. Early treatment may allow
men to live a little longer. Other doctors say to wait, because waiting delays
the bothersome and serious side effects of hormone therapy.
Treatment for metastatic prostate cancer
Treatment for
prostate cancer that has spread to the bones and/or
other organs in the body is aimed at relieving symptoms and slowing the
cancer's growth. Treatment may include:
Hormone therapy works by decreasing the amount of testosterone in your body. This can be done with medicine or with surgery to remove the testicles (orchiectomy). Hormone therapy can also relieve pain by shrinking tumors and easing urinary
problems.
Sometimes
androgen deprivation (orchiectomy or an LH-RH agonist) and an antiandrogen are
used together. This is called a combined androgen blockade (CAB). But the slight benefit of CAB may be offset by side effects.
Both orchiectomy and hormone therapy medicine make
testosterone levels drop, causing some of the same side effects. These include
larger breasts,
hot flashes, loss of sexual desire, and the inability
to have an erection. Treatment options for these problems include:
- Taking a temporary break from hormone therapy. This can make
some side effects go away. (Side effects after orchiectomy are
permanent.)
- Radiation treatment of the breasts to prevent breast growth.
This is done before starting hormone therapy.
- Radiation treatment or the anti-estrogen breast cancer medicine
called tamoxifen to relieve breast pain. Tamoxifen can also help reverse breast
growth. It also causes hot flashes.
- Taking medicines to control hot flashes, such as venlafaxine or
paroxetine. If these don't work, sometimes estrogen or
megestrol may help reduce hot flashes. But all of these medicines have
different side effects, so if you are having a problem with hot flashes, talk
with your doctor.
Other serious side effects of hormone therapy may include thin or brittle bones (osteoporosis), reduced muscle mass, increased body mass (BMI), low red blood cell counts (anemia), fatigue, cognitive impairment (trouble thinking clearly), depression, and an increased risk for diabetes and heart disease.
Hormone therapy usually works well at first to stop
cancer growth. But in most cases the cancer returns in a few years. At this
point, the cancer is described as hormone-resistant,
meaning it is not responding to standard hormone therapy. When this happens,
other kinds of hormone treatment may be tried. If the cancer continues to grow,
chemotherapy may be recommended.
Other hormone therapies may
include the use of medicines such as megestrol acetate, estrogen, ketoconazole,
aminoglutethimide combined with hydrocortisone, and corticosteroids
(prednisone, dexamethasone, and hydrocortisone).
Some men choose
to start hormone therapy only after they have symptoms. But many doctors
recommend starting hormone therapy right away if cancer is found in the
lymph nodes during surgery to remove the prostate. Early treatment may allow
men to live a little longer. Other doctors say to wait, because waiting delays
the bothersome and serious side effects of hormone therapy.
Alternatives to conventional
hormone therapy include intermittent ADT, known as IAD,
where men take cycles of hormone therapy medicines. Taking breaks between
hormone therapy cycles gives men the chance to recover their ability to
function sexually. It also gives relief from the other side effects of hormone
therapy, including the loss of energy, loss of bone and muscle mass, and hot
flashes. The long-term survival outcome of IAD compared to conventional ADT is
not yet known, but from early studies, it looks like they both work about the
same.5
For more information about
specific treatments, see the following topics:
What to think about
You may experience a wide variety of emotions after being diagnosed. Most men feel some denial, anger, and grief. Others feel nothing at all. It is normal to have a wide range of feelings. And it is normal for your feelings to change quickly. There are many things you can do to help with your
emotional reaction to prostate cancer. You may find
that talking with family and friends helps you with your emotions. Some men
find that spending time alone is what they need.
If your reaction
is interfering with your ability to make decisions about your health, be sure to talk with your doctor. Your cancer treatment center may offer
psychological or financial services. You may also ask your local chapter of
the American Cancer Society to help you find a support group. Talking with
other men who have had similar feelings can help a lot.
Long-term hormone therapy can also lead to
osteoporosis, which causes bones to become brittle and
more likely to break. Drugs are available to help prevent this side effect. For
more information, see the topic
Osteoporosis.
There are many studies
(clinical trials) focusing on finding ways to prevent, detect, diagnose, and
treat prostate cancer in all stages. Talk to your doctor about whether entering
a clinical trial is a good option for you to explore.
Palliative care
If your cancer gets worse, look
into your options for
palliative care. Palliative care is a kind of care for
people who have illnesses that do not go away and often get worse over time. It
is different from trying to cure your illness. Palliative care focuses on
improving your quality of life—not just in your body but also in your mind and
spirit. Some people combine palliative care with curative care.
With prostate cancer, palliative care may involve treatments to reduce
tumors or bone pain, such as
chemotherapy,
radiation therapy, radionuclides (medicine used in
external radiation) for bone metastasis, and
bisphosphonates, which slow the breakdown of bone and
help relieve bone pain. Surgery to relieve bladder problems (transurethral resection of the prostate, or TURP) is
also an option.
Palliative care may help you manage symptoms or side effects from
treatment. It could also help you cope with your feelings about living with a
long-term illness, make future plans around your medical care, or help your
family better understand your illness and how to support you.
If
you are interested in palliative care, talk to your doctor. He or she may be
able to manage your care or refer you to a doctor who specializes in this type
of care.
For more information, see the topic
Palliative Care.
End-of-life issues
You may wish to
discuss health care and other legal issues that arise near the end of life with
your family and your doctor. You may find it helpful and comforting to state
your health care choices in writing—with an
advance directive or living will—while you are still
able to make and communicate these decisions.
Think about your treatment
options and which kind of treatment will be best for you. You may want to
choose a
health care agent to make and carry out decisions
about your care if you should become unable to speak for yourself. Be sure to share your wishes with your family or close friends.
You can get forms from Caring Connections (www.caringinfo.org or 1-800-658-8898) or Aging With Dignity (www.agingwithdignity.org or 1-888-594-7437).
For more
information, see the topic
Care at the End of Life.
Hospice care provides medical services,
emotional support, and spiritual resources for people who are at the end of
life. Hospice care also helps family members manage the practical details and
emotional challenges of caring for a dying loved one. For more information, see
the topic
Hospice Care.
Prevention
Prostate cancer
can't be prevented. But there are steps you can take to reduce your risk of
developing this disease. For more information, see the topic
Prostate Cancer.
Home Treatment
During medical care for any stage of
prostate cancer, there are things you can do at home
to help manage symptoms of prostate cancer or side effects of treatment:
-
Nausea or vomiting. After vomiting has stopped for 1
hour, sip a
rehydration drink to restore lost fluids and
nutrients. Watch for and treat early signs of
dehydration. Older adults can quickly become
dehydrated from vomiting. Your doctor may also prescribe
medicines to control nausea and vomiting. For more
information on how to deal with these side effects, see:
- Cancer: Controlling Nausea and Vomiting From Chemotherapy.
-
Pain. For pain, talk to your doctor about using
aspirin, acetaminophen (such as Tylenol), or another type of
nonsteroidal anti-inflammatory drug (NSAID). Or ask
about a
narcotic medicine. You can also try an alternative
therapy such as
biofeedback. Be sure to discuss with your doctor any
home treatment you use for pain.
-
Diarrhea. Don't eat until you are feeling better. Take
frequent, small sips of water or a rehydration drink and small bites of salty
crackers. Begin eating mild foods (such as rice, dry toast or crackers,
bananas, broth, and applesauce) the next day or sooner, depending on how you
feel.
-
Constipation. Make sure you drink enough fluids. Most
adults should drink between 8 and 10 glasses of water or noncaffeinated
beverages each day. Include fruits, vegetables, and fiber in your diet each
day.
-
Sleep problems. Often, simple measures such as having
a regular bedtime, getting some exercise during the day, and avoiding caffeine
late in the day can relieve sleep problems.
-
Urinary problems. Home treatment for urinary
incontinence includes eliminating caffeinated drinks from your diet and
establishing a schedule of urinating every 3 to 4 hours, regardless of whether
you feel the need. You may also try doing
pelvic floor (Kegel) exercises to strengthen your
pelvic muscles.
During medical treatment for prostate cancer, you may
experience emotional problems. See the following tips for managing:
-
Stress. Expressing your feelings to others may help
you understand and cope with them. Learning relaxation techniques may also be
helpful.
-
Poor body image. Your feelings about your body may
change after treatment for cancer. Talk openly about your concerns with your
partner. And discuss your feelings with your doctor, who may also be able to
refer you to groups that can offer support and information.
Pain from cancer or its treatments can almost always be managed. If pain becomes a problem, talk to your doctor about seeing a pain management specialist. For tips on pain management, see:
-
Cancer: Controlling Cancer Pain.
For more information, see the topic
Cancer Pain.
Medications
Medicines may be used to slow the growth of
prostate cancer and to relieve your symptoms.
Prostate cancer needs the male hormone
testosterone to grow. Hormone therapy uses special
drugs to block the production or action of testosterone and may cause the
cancer to shrink. This can improve your symptoms. Hormone therapy may be given
before or after
radiation or
surgery to remove the prostate.
Chemotherapy
is the use of drugs to control cancer's
growth or relieve pain. Often the drugs are given through a needle in your
vein, and your blood vessels carry the drugs through your body. Sometimes the
drugs are available as pills you can swallow. Sometimes they are given through
a shot, or injection.
Chemotherapy usually involves two or more
drugs given together. This is done to lower the chances that the cancer cells
will become resistant to the drugs. It is most often used when prostate cancer
is hormone-resistant.
Hormone therapy usually works well at
first to stop cancer growth. But in most cases the cancer returns in a few
years. At this point, the cancer is called hormone-resistant. This means it will no longer get better
with hormone therapy. When this happens, other kinds of hormone treatment may
work. If the cancer continues to grow, chemotherapy may be the next choice.
Medication Choices
Hormone therapy
-
LH-RH agonists/GnRH agonists, such as leuprolide
(Lupron) and goserelin (Zoladex)
- GnRH antagonists, such as degarelix (Firmagon).
-
Antiandrogens, such as flutamide, nilutamide
(Nilandron), and bicalutamide (Casodex)
Hormone therapy for prostate cancer also includes
orchiectomy, which is the surgical removal of the
testicles. Hormone therapy is commonly used with radiation therapy. It may be used alone with metastatic cancer.
Chemotherapy
Chemotherapy may be helpful when prostate cancer no longer responds to hormone therapy.
Pain-relief and appetite-stimulant drugs
Pain-relief and appetite-stimulant drugs may be used when prostate cancer
has spread to other parts of the body.
-
Steroids, such as hydrocortisone or prednisone,
control pain and improve appetite.
- Radioactive drugs such as strontium-89 and samarium-153 are
called radionuclides. They are absorbed near the area of bone pain. Then the
radiation that is released helps relieve the pain caused by tumors that have
spread to the bone.
-
Bisphosphonate drugs such as zoledronic acid (Zometa) and pamidronate disodium (Aredia) may help relieve
bone pain and prevent
osteoporosis, which is sometimes caused by long-term
hormone therapy.
Pain medicines are made that specifically treat mild,
moderate, and severe pain, as well as different types of pain such as burning
and tingling. To learn more, see:
-
Cancer: Controlling Cancer Pain.
For more information, see the topic
Cancer Pain.
Medicines for treating side effects
Hormone
therapy can cause loss of sexual desire,
hot flashes, enlarged and painful breasts, and
erection problems.
- For men who have erectile problems after surgery, medicines
such as sildenafil (Viagra), vardenafil (Levitra), or tadalafil (Cialis) may be
helpful. Using medicines soon after surgery may help men regain sexual function. Talk with your doctor about your situation.
- Taking a temporary break from hormone therapy can make some
side effects go away.
- To relieve breast pain, the anti-estrogen breast cancer
medicine called
tamoxifen or radiation treatment is commonly used.
Tamoxifen can also help reverse breast growth. It also causes hot
flashes.
- For hot flashes, taking a certain kind of
antidepressant may help.
Venlafaxine or paroxetine may help with hot flashes. But they have different side effects. So if you are having a problem with hot flashes, talk
with your doctor.
What to Think About
Antiandrogen hormone therapy also
may cause diarrhea, breast tenderness, and nausea. Cases of liver problems,
some serious, have been reported.
When surgery or hormone therapy
reduces the body's hormones, the bones may begin to lose their mineral density.
Bone mineral density refers to how many minerals—which make your bones
stronger—are in your bones. Bones that become thin and brittle are more likely
to break, and studies show that hormone therapy increases the likelihood of
broken bones.6 Pills or shots of a medicine called
bisphosphonate can help prevent bone loss during long-term hormone therapy.
These medicines may also help men whose prostate cancer has spread to the
bones. Regular exercise also helps. For more information, see the topic
Osteoporosis.
Surgery
Surgery to treat
prostate cancer is usually reserved for men in good
health who are younger than 70 and who choose to have surgery. Surgery may be
done to relieve symptoms and to slow the growth of cancer.
Surgery Choices
-
Radical prostatectomy, the removal of the prostate and
its cancer. It is not usually done if the cancer has spread to other parts of
the body.
-
Orchiectomy, the removal of the testicles. This may
cause the cancer to shrink and may improve symptoms because prostate cancer
often needs the testosterone made by the testicles to grow.
-
TURP, or transurethral resection of the prostate. This
operation can help to relieve bladder problems because it removes part of the
tumor that may be blocking the urethra, the tube that carries urine from your
bladder through your penis. This can keep the tumor from growing for a while.
But TURP does not take out the whole tumor.
What to Think About
Surgical
removal of the testicles (orchiectomy) and hormone therapy medicines have some
of the same side effects, including hot flashes, larger breasts, loss of sexual
desire, and the inability to have an erection.
Other Treatment
Radiation therapy
Radiation therapy for
prostate cancer may be used alone or combined with
hormone treatment. In rare cases, it is used with surgery. It is most effective
in treating cancers that have not spread beyond the prostate, but it can also
be effective in treating cancer that is only in the tissue near the prostate
(locally advanced prostate cancer). Radiation therapy also is used to relieve
pain from metastatic cancer or cancer that comes back after surgery.
Radiation therapy for locally advanced prostate cancer is often combined
with hormone treatment. Using both together improves your chances of being
disease-free for longer and living longer.2
External-beam radiation therapy uses a large machine
to aim a beam of radiation at your tumor to destroy cancer cells. The radiation
damages the genetic material of the cells so that they can't grow. Although
radiation damages normal cells as well as cancer cells, the normal cells can
repair themselves and function, while the cancer cells cannot. If cancer has
spread to your bones, radiation treatment may be given to specific areas to
relieve pain.
Side effects
Radiation treatment commonly has
side effects, including
urinary incontinence, inflammation of the bladder and
colon (colitis), diarrhea, and erection problems.
Side effects
are common. Some men develop long-term problems that may have a significant
impact on the quality of their lives. Long-term problems that can be caused by
radiation treatment include:
- An irritated rectum and an urgent need to pass a stool. This is
called proctitis.
- An inflamed bladder and urination problems. This is called
cystitis.
- An inflamed intestine and diarrhea. This is called
enteritis.
- Being unable to have an erection. This is called
impotence.
- Being unable to control urination. This is called
incontinence.
- Painful urination. This is called dysuria.
Immunotherapy
Researchers also are testing many new ways to treat prostate cancer using
the body's
immune system to destroy the cancer cells. This type
of treatment is called immunotherapy. Much has been
learned in the past 20 years about the body's ability to attack prostate cancer
cells with help from the outside. And research is still being done in this
area. This type of treatment either stimulates your immune system or adds to
it, for example, by giving you immune cells from another person.
Vaccines such as Provenge use cells from a man's own body to stimulate his immune system. This can slow the growth of prostate cancer.
Complementary therapy
People sometimes use complementary therapies along with medical treatment to help relieve symptoms and side effects of cancer treatments. Some of the complementary therapies that may be helpful include:
Mind-body treatments like those mentioned above may help you feel better and cope better with treatment. These treatments also may reduce chronic low back pain, joint pain, headaches, and pain from cancer treatments.
Before you try a complementary therapy, talk to your doctor about
the possible value and potential side effects. Let your doctor know if you are
already using any such therapies. Complementary therapies are not meant to take
the place of standard medical treatment, but they may improve your quality of
life and help you deal with the stress and side effects of cancer treatment.
Clinical trials
You
may be interested in taking part in research studies called clinical trials. Clinical trials are designed to
find better ways to treat prostate cancer patients and are based on the most up-to-date information. People who do not want standard treatments or are not cured by standard treatments may want to take part in
clinical trials.
Check with your doctor to see whether clinical trials are in your area and whether you might be eligible.
