Description

A prostate-specific antigen (PSA) test measures the level of PSA in a blood sample to help screen for prostate cancer: 

What is PSA?

• PSA is a protein produced by the prostate gland, which is part of the male reproductive system. PSA is also found in semen. 

What does a PSA test show?

• A higher PSA level in the blood can indicate a prostate problem, such as prostate cancer, an enlarged prostate, or a prostate infection. However, many other factors can affect PSA levels including age, race, certain medications, and medical procedures. 

When should I get a PSA test?

• Most healthcare providers recommend getting a PSA test every two to three years, starting around age 50. If you have a high risk of prostate cancer, you may want to get regular PSA tests starting around age 40.
