What is a Prostate-specific Antigen (PSA) test?
A PSA test measures the amount of Prostate-specific Antigen, a protein present in both healthy and cancerous cells of the prostate gland. Prostate gland is part of the male reproductive system that produces the fluid which carries sperms during ejaculation.
A PSA test is generally performed along with a digital rectal exam (DRE) to check for prostate cancer and determine the nature of the problem in men who may or may not experience any apparent symptoms of the condition.
