Cancer occurs when cells in the body begin changing and multiplying out of control. These cells can form lumps of tissue called tumors. Cancer that starts in the prostate is called prostate cancer. Cancer can grow and spread beyond the prostate, threatening health and life.

Important answers about prostate cancer and the fears that accompany it.

When problems occur in the prostate, the bladder and urethra are often affected as well. Urinary symptoms can result.

If your health care provider has told you that you have prostate cancer, you may soon face a difficult choice of treatment options.

PSA, an ingredient of semen, is made by the prostate. Some PSA naturally leaks from the prostate into the bloodstream. The PSA test measures the amount of PSA in the blood. As a man ages, more PSA leaks into the blood.

If a potential prostate problem is identified through a digital rectal exam or a PSA (prostate-specific antigen) blood test, your doctor may suggest that you have an ultrasound.

If the results of your exam and tests lead your doctor to suspect prostate cancer, a core needle biopsy will be done. A thin needle is used to remove small samples of prostate tissue. These samples are checked for cancer.

If you are a man, you are at risk for prostate cancer. The risk for prostate cancer increases with age. Your risk is also higher if you are African-American or have a family history of prostate cancer.
