Prostate Cancer Screening test measures the amount of prostate-specific antigen in the blood. Prostate-specific antigen (PSA) is a substance released into a man's blood by his prostate gland. Low amounts of PSA may be found in the blood of healthy men. The amount of PSA in the blood normally increases as a man's prostate enlarges with age. It is also increased by inflammation of the prostate gland (prostatitis) and by prostate cancer.
Prostate cancer often grows very slowly, without causing major problems. Prostate cancer screening test helps in detecting prostate cancer at an early stage which can be aid in treating it and may also help in preventing other cancer-related health problems and reduce the risk of dying from the cancer.
In men who have total PSA values between 4.0 and 10.0, it is important to differentiate between free and total PSA. A percent free PSA may be used to determine the relative risk of prostate cancer.
