When Chris Muraithi, turned 45, he started going for regular tests to check his prostate. One of the tests performed during his visits to a medical facility is one that measures the level of Prostate-specific antigen (PSA) in the blood.

PSA, is a protein produced by normal, as well as malignant, cells of the prostate gland. The blood level of PSA is often elevated in people with prostate cancer. The PSA level may also be elevated in other conditions that affect the prostate.
