Prostate cancer is a group of cancerous cells (a malignant tumor) that begins most often in the outer part of the prostate. It is the most common type of cancer (excluding skin cancer) diagnosed in American men. In 2003, an estimated 220,900 new cases of prostate cancer will be diagnosed in the U.S.

Early prostate cancer usually does not cause any symptoms. However, as the tumor grows, it may spread from the prostate to surrounding areas. Change in urination, including increased frequency, hesitancy or dribbling of urine may be experienced.

Prostate cancer can spread from the prostate to nearby lymph nodes, bones or other organs. This spread is called metastasis. For example, as a result of metastasis to the spine, some men experience back pain.
