Prostate cancer is the
abnormal growth of cells in a man's
prostate gland . The prostate sits just below the bladder. It makes part of the

cancer is common in men older than 65. It usually grows slowly and can take
years to grow large enough to cause any problems. As with other cancers, treatment for prostate cancer works best when the cancer is found early. Often, prostate cancer that has spread responds to treatment. Older men who have prostate cancer usually die from other causes.

that you have an enlargement or infection of the prostate.
PSA is high,
you may need a
prostate biopsy to figure out the cause. A biopsy means that your
doctor takes tissue samples from your prostate gland and sends them to a lab
