Prostate cancer is cancer that occurs in a man's prostate — a small walnut-shaped gland that produces the seminal fluid that nourishes and transports sperm.
Prostate cancer is one of the most common types of cancer in men. Prostate cancer usually grows slowly and initially remains confined to the prostate gland, where it may not cause serious harm. While some types of prostate cancer grow slowly and may need minimal or no treatment, other types are aggressive and can spread quickly.
Prostate cancer that is detected early — when it's still confined to the prostate gland — has a better chance of successful treatment.

Prostate cancer may not cause signs or symptoms in its early stages. Prostate cancer that is more advanced may cause signs and symptoms such as:
When to see a doctor
Make an appointment with your doctor if you have any signs or symptoms that worry you.
Ask your doctor about the benefits and risks of regular prostate cancer screening. Medical organizations differ on their recommendations for prostate cancer screening, but many advise men in their 50s to discuss the issue with their doctors.

It's not clear what causes prostate cancer. Doctors know that prostate cancer begins when some cells in your prostate become abnormal. Mutations in the abnormal cells' DNA cause the cells to grow and divide more rapidly than normal cells do. The abnormal cells continue living, when other cells would die. The accumulating abnormal cells form a tumor that can grow to invade nearby tissue. Some abnormal cells can break off and spread (metastasize) to other parts of the body.

If you have signs or symptoms that worry you, start by seeing your family doctor or a general practitioner. If your doctor suspects you may have a problem with your prostate, you may be referred to a urinary tract specialist (urologist). If you're diagnosed with prostate cancer, you may be referred to a cancer specialist (oncologist) or a specialist who uses radiation therapy to treat cancer (radiation oncologist).
Because appointments can be brief, and because there's often a lot of ground to cover, it's a good idea to be prepared. Here's some information to help you get ready, and what to expect from your doctor.
What you can do
Your time with your doctor is limited, so preparing a list of questions will help you make the most of your time together. List your questions from most important to least important in case time runs out. For prostate cancer, some basic questions to ask your doctor include:
In addition to the questions that you've prepared to ask your doctor, don't hesitate to ask other questions during your appointment.
What to expect from your doctor
Your doctor is likely to ask you a number of questions. Being ready to answer them may allow more time later to cover other points you want to address. Your doctor may ask:

Screening for prostate cancer
Whether to test healthy men with no prostate symptoms for prostate cancer is controversial. Medical organizations don't agree on the issue of screening and whether it has benefits. Some medical organizations recommend men consider prostate cancer screening in their 40s, or sooner for men who have risk factors for prostate cancer. Other organizations advise against screening. Discuss your particular situation and the benefits and risks of screening with your doctor. Together you can decide whether prostate cancer screening is appropriate for you.
Prostate screening tests might include:
PSA testing combined with DRE helps identify prostate cancers at their earliest stages, but studies haven't proved that these tests save lives. For that reason, there is much debate surrounding prostate cancer screening.
Diagnosing prostate cancer
If an abnormality is detected on a DRE or PSA test, your doctor may recommend tests to determine whether you have prostate cancer, such as:
Determining whether prostate cancer is aggressive
When a biopsy confirms the presence of cancer, the next step, called grading, is to determine how aggressive the cancer is. The tissue samples are studied, and the cancer cells are compared with healthy prostate cells. The more the cancer cells differ from the healthy cells, the more aggressive the cancer and the more likely it is to spread quickly. More-aggressive cancer cells have a higher grade.
The most common scale used to evaluate the grade of prostate cancer cells is called a Gleason score. Scoring combines two numbers and can range from 2 (nonaggressive cancer) to 10 (very aggressive cancer).
Determining how far the cancer has spread
Once a cancer diagnosis has been made, your doctor works to determine the extent (stage) of the cancer. Many men won't require these additional tests. But if your doctor suspects your cancer may have spread beyond your prostate, imaging tests such as these may be recommended:
Once testing is complete, your doctor assigns your cancer a stage. This helps determine your treatment options. The prostate cancer stages are:

Your prostate cancer treatment options depend on several factors, such as how fast your cancer is growing, how much it has spread, your overall health, as well as the benefits and the potential side effects of the treatment.
Immediate treatment may not be necessary
For men diagnosed with a very early stage of prostate cancer, treatment may not be necessary right away. Some men may never need treatment. Instead, doctors sometimes recommend watchful waiting, which is sometimes called active surveillance. In watchful waiting, regular follow-up blood tests, rectal exams and possibly biopsies may be performed to monitor progression of your cancer.
If tests show your cancer is progressing, you may opt for a prostate cancer treatment such as surgery or radiation. Watchful waiting may be an option for cancer that isn't causing symptoms, is expected to grow very slowly and is confined to a small area of the prostate. Watchful waiting may also be considered for a man who has another serious health condition or an advanced age that makes cancer treatment more difficult. Watchful waiting carries a risk that the cancer may grow and spread between checkups, making it less likely to be cured.
Radiation therapy
Radiation therapy uses high-powered energy to kill cancer cells. Prostate cancer radiation therapy can be delivered in two ways:
Side effects of radiation therapy can include painful urination, frequent urination and urgent urination, as well as rectal symptoms, such as loose stools or pain when passing stools. Erectile dysfunction can also occur. There is a small risk of radiation causing another form of cancer, such as bladder cancer or rectal cancer, in the future.
Hormone therapy
Hormone therapy is treatment to stop your body from producing the male hormone testosterone. Prostate cancer cells rely on testosterone to help them grow. Cutting off the supply of hormones may cause cancer cells to die or to grow more slowly. Hormone therapy options include:
Hormone therapy is used in men with advanced prostate cancer to shrink the cancer and slow the growth of tumors. In men with early-stage prostate cancer, hormone therapy may be used to shrink tumors before radiation therapy. This can make it more likely that radiation therapy will be successful. Hormone therapy is sometimes used after surgery or radiation therapy to slow the growth of any cancer cells left behind.
Side effects of hormone therapy may include erectile dysfunction, hot flashes, loss of bone mass, reduced sex drive and weight gain. Hormone therapy also increases the risk of heart disease and heart attack.
Surgery to remove the prostate
Surgery for prostate cancer involves removing the prostate gland (radical prostatectomy), some surrounding tissue and a few lymph nodes. Ways the radical prostatectomy procedure can be performed include:
Discuss with your doctor which type of surgery is best for your specific situation.
Radical prostatectomy carries a risk of urinary incontinence and erectile dysfunction. Ask your doctor to explain the risks you may face based on your situation, the type of procedure you select, your age, your body type and your overall health.
Freezing prostate tissue
Cryosurgery or cryoablation involves freezing tissue to kill cancer cells. During cryosurgery for prostate cancer, small needles are inserted in the prostate using ultrasound images as guidance. A very cold gas is placed in the needles, which causes the surrounding tissue to freeze. A second gas is then placed in the needles to reheat the tissue. The cycles of freezing and thawing kill the cancer cells and some surrounding healthy tissue. Initial attempts to use cryosurgery for prostate cancer resulted in high complication rates and unacceptable side effects. However, newer technologies have lowered complication rates, improved cancer control and made the procedure easier to tolerate. Cryosurgery may be an option for men who haven't been helped by radiation therapy.
Heating prostate tissue using ultrasound
High-intensity focused ultrasound treatment uses powerful sound waves to heat prostate tissue, causing cancer cells to die. High-intensity focused ultrasound is done by inserting a small probe in your rectum. The probe focuses ultrasound energy at precise points in your prostate. High-intensity focused ultrasound treatments are being studied in clinical trials. More study is needed to understand the benefits and risks of this treatment.
Chemotherapy
Chemotherapy uses drugs to kill rapidly growing cells, including cancer cells. Chemotherapy can be administered through a vein in your arm, in pill form or both. Chemotherapy may be a treatment option for men with prostate cancer that has spread to distant areas of their bodies. Chemotherapy may also be an option for cancers that don't respond to hormone therapy.

No complementary or alternative treatments will cure prostate cancer. However, complementary and alternative prostate cancer treatments may help you cope with the side effects of cancer and its treatment.
Alternative prostate cancer treatments that may help you cope with the stress and anxiety you may experience after your diagnosis include:
Ask your doctor to refer you to a professional who can help you learn to do these activities. Some require instruction, while others can be done on your own.
