Biomarker Signatures of Prostate Cancer

Prostate cancer is the second most common cancer in men in the United States. This buildup of abnormal cells in a man's prostate -- a gland below the bladder and in front of the rectum -- often has no early symptoms and usually grows very slowly. Treatment choices depend on many factors. More than half of prostate cancers stay within the gland and don't become life-threatening. But doctors don't have a way to reliably predict which tumors will progress and which are unlikely to cause problems.
