CauseThe 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. SymptomsProstate cancer may not cause noticeable symptoms. Possible symptoms of locally advanced prostate cancer are:
These symptoms also may be caused by:
Symptoms that may indicate the cancer has spread to other parts of the body, or metastasized, include:
What HappensProstate cancer is so common that some experts believe every man would get it if he lived long enough. Studies of autopsies show that most men older than 85 who die of other causes have tumors in their prostates. 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. 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. While most men live 1 to 3 years after this diagnosis, some men may live many years longer. What Increases Your RiskA 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. 2 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 increases even more if those relatives were diagnosed before they were 55. 1 Most men who get prostate cancer have no family history of the disease. Most men will die with prostate cancer but not from prostate cancer. 3 Your chances of dying from the disease depend on:
If you have prostate cancer, your chances of dying from it are influenced by:
Race and prostate cancer survivalAfrican-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. 5 Ethnicity and 5-year survival (percentage of men who survive for 5 years or more after prostate cancer is diagnosed) 4
The 5-year survival rate shows the percentage of men who are still alive 5 years or longer after they are diagnosed. It is important to remember that these are only averages. Everyone’s case is different, and these numbers may not show what will happen in your case. When To Call a DoctorCall your doctor immediately if you:
Call your doctor to schedule an appointment if you have unexplained:
Watchful WaitingWatchful waiting means that you are not receiving treatment but you and your doctor will watch your cancer to see if your symptoms go away on their own or get worse. Watchful waiting may not be a choice when prostate cancer has spread. But some men who have metastatic prostate cancer may choose watchful waiting if their PSA levels are rising slowly. If you choose watchful waiting, you will still need to see your doctor regularly for digital rectal exams and PSA tests. Who To SeeDoctors 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 TestsLocally advanced and metastatic prostate cancer are diagnosed through physical exams and tests, including:
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:
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 may show the need for further tests, such as a prostate biopsy, bone scan, CT scan, or MRI. Treatment OverviewChoosing 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 decision depends on:
Treatment for locally advanced or metastatic prostate cancer may include hormone therapy, surgery, radiation therapy, chemotherapy, and pain medicine. You may want to talk with your doctor about entering a clinical trial of new cancer treatment options. You may experience a wide variety of emotions after being diagnosed. Most men feel some denial, anger, and grief. Others may have fewer emotions. There is no "normal" way to react. 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, it is important to talk with your doctor. Your cancer treatment center may offer psychological or financial services. You may also contact 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 be very helpful. 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 does not have to be an accepted part of treatment for prostate cancer. For tips on handling pain, see: For more information, see the topic Cancer Pain. Localized prostate cancer is cancer that is small and 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 cancerProstate cancer that has spread to tissue around the prostate may be treated with:
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 side effects of ADT. Treatment for metastatic prostate cancerTreatment 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:
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:
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 side effects of ADT. 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. 12 For more information about specific treatments, see the following topics:
What to think aboutVaccines to keep prostate cancer from coming back after it has been treated are being tested. This type of treatment encourages the body's immune system to destroy cancer cells that remain after prostate cancer surgery. Early results suggest that vaccines may be able to help slow the growth of prostate cancer. 13 A study suggests that advanced prostate cancer can sometimes be cured if the cancer has spread to only a few lymph nodes and great care is used to completely remove the lymph nodes during prostatectomy. 14 Radiation and hormone treatment may be used afterwards to destroy any remaining cancer cells. 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. Having a healthy weight may help you survive this disease. Studies have shown that men who have prostate cancer are more likely to die from the disease if they are obese, as defined by a body mass index of 30 or higher. 7, 8 Palliative careIf 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. Studies show that men with advanced prostate cancer who took bisphosphonates had better pain relief and fewer bone problems, although they had some nausea. 15 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 issuesLocally advanced or metastatic prostate cancer often cannot be cured. 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. For more information, see the topic Care at the End of Life. A time may come when your goals or the goals of your loved ones change from treating or curing your illness to maintaining your comfort and dignity. Your doctor will be able to address questions or concerns about maintaining comfort when cure is no longer an option. 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. PreventionProstate 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 TreatmentDuring 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:
During medical treatment for prostate cancer, you may experience emotional problems. See the following tips for managing:
You should not have to accept pain as part of receiving cancer treatment or having cancer. For tips on pain management, see: For more information, see the topic Cancer Pain. MedicationsMedicines may be used to slow the growth of prostate cancer and to relieve your symptoms. Prostate cancer often 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 ChoicesHormone therapy
Hormone therapy for prostate cancer also includes orchiectomy, which is the surgical removal of the testicles. Hormone therapy is rarely used alone. More commonly, it is used with radiation therapy. Chemotherapy
Having chemotherapy with docetaxel and other medicine helps men with metastatic hormone-resistant prostate cancer live longer. A study with 1,006 men found that chemotherapy with docetaxel taken along with prednisone showed longer survival and a better quality of life. 11 Pain-relief and appetite-stimulant drugsPain-relief and appetite-stimulant drugs may be used when prostate cancer has spread to other parts of the body.
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: For more information, see the topic Cancer Pain. Medicines for treating side effectsHormone therapy can cause loss of sexual desire, hot flashes , enlarged and painful breasts, and erection problems.
What To Think AboutAntiandrogen 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. 18 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. SurgerySurgery 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
What To Think AboutA study suggests that advanced prostate cancer can sometimes be cured if the cancer has spread to only a few lymph nodes and great care is used to completely remove the lymph nodes during prostatectomy. 14 Radiation and hormone treatment may be used afterwards to destroy any remaining cancer cells. 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 TreatmentRadiation 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. 6
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:
Complementary therapy Complementary therapies, such as acupuncture , herbs, biofeedback , meditation , yoga, and vitamins , are sometimes used along with medical treatment. Some people feel that they benefit from some of these therapies. 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 Clinical trials are ongoing to find ways to prevent, detect, diagnose, and treat prostate cancer. For example, scientists are testing vaccines that use the immune system to keep cancer from getting worse. Other studies are testing on-and-off hormone therapy for men who have advanced prostate cancer. Hormone therapy lasts until cancer growth stops, then begins again when the cancer progresses. These trials hope to prove that men can avoid some of the side effects of continuous hormone therapy and still receive treatment that will block cancer growth. 19 If you are interested in taking part in this type of trial, contact the U.S. National Cancer Institute Clinical Trials Support Unit (www.ctsu.org).
