PSA or Prostate-Specific-Antigen is a type of protein produced in the prostate. According to the American Cancer Society PSA is found in semen, but small amounts can also be found in the male bloodstream 1. Generally the higher your PSA level, the greater your risk of prostate cancer.

Levels

According to the American Cancer Society healthy males have levels under 4 ng/ml (nanograms per milliliter) of blood 1. A level of seven would put you between 4 and 10, giving you a 1 in 4 chance of having prostate cancer. Any level above 10, gives you a 50 percent chance.
