PSA (Prostate Specific - Antigen Test)

PSA test is an effective screening test for prostrate cancer. It involves testing a sample of blood to measure the level of prostate-specific antigen in your blood. Prostate-specific antigen (PSA) is a substance released into a man's blood by his prostate gland. Higher levels of PSA than the normal level shows there is a problem.

Screening is usually done for men older than age 50 or for those who have a family history of prostate cancer. Other medical conditions like enlargement or inflammation of prostate gland can also cause high PSA levels, therefore, further tests such as a prostate biopsy are needed to confirm a diagnosis of prostate cancer.

The normal PSA level of each individual depends on your age and other factors.
