Prostate The Oklahoma Blood Institute is the first donor center in the United States to offer Prostate-Specific Antigen testing to male donors over age 30. A PSA test measures PSA levels in blood. An elevated PSA level may be a warning sign in men for prostate cancer, or other urinary tract diseases.
Prostate cancer is the second leading cause of cancer death in men.
African-American men, men over 55 years old, and men with a family history of prostate cancer are more likely to get prostate cancer during their lifetime. If either result is suspicious, more extensive tests may be needed. Cancer of the prostate usually involves enlargement of the gland. The prostate is a walnut-size male sex gland, located below the bladder and in front of the rectum. Any enlargement should be investigated.
