Cancer - prostate
Definition:
A malignant tumor growth within the prostate gland.
Causes and Risks The cause of prostate cancer is unknown, although some studies have shown a relationship between high dietary fat intake and increased testosterone levels. When testosterone levels are lowered either by surgical removal of the testicles (orchiectomy) or by medication, prostate cancer can regress. There is no known association with benign prostatic hyperplasia (BPH). Men at higher risk include black men over 60 years old, farmers, tire workers, painters, and men exposed to cadmium. The lowest incidence occurs in Japanese men and vegetarians. This system also contains several substages.
Prostate cancer is the third most common cause of death from cancer in men of all ages and is the most common cause of death from cancer in men over 75 years old. Prostate cancer is rarely found in men younger that 40 years of age.
Prostate cancers are classified or staged based on their aggressiveness and how different they are from the surrounding prostate tissue. There are several different ways to stage tumors; one of the more common is the A-B-C-D staging system (also known as the Whitmore-Jewett system).
