Adenocarcinoma of the prostate is the clinical term for a cancerous tumor on the prostate gland. As prostate cancer grows, it may spread to the interior of the gland, to tissues near the prostate, to sac-like structures attached to the prostate (seminal vesicles), and to distant parts of the body (e.g., bones, liver, lungs). Prostate cancer confined to the gland often is treated successfully.

Anatomy
The prostate gland is located in the pelvis, below the bladder, above the urethral sphincter and the penis, and in front of the rectum in men. It is made up of glandular tissue and muscle fibers that surround a portion of the urethra. The gland is covered by a membrane (called the prostate capsule) that produces prostate-specific antigen.

Incidence and Prevalence
According to the American Cancer Society (ACS), prostate cancer is the most common type of cancer in men in the United States, other than skin cancer. The ACS estimates that about 218,890 new cases will be diagnosed in 2007 and about 27,050 men will die of the disease. Prostate cancer is the second leading cause of cancer death in men, exceeded only by lung cancer.
