Prostate Cancer

Prostate cancer is cancer of the prostate, a gland in the male reproductive system that surrounds the urethra just below the bladder. Most prostate cancers are slow-growing. Cancerous cells may spread to other areas of the body, particularly the bones and

lymph nodes

. It may initially cause no symptoms. In later stages, symptoms include pain or difficulty urinating, blood in the urine, or pain in the pelvis or back. Other late symptoms include fatigue, due to low levels of red blood cells.
