M.D. Doctors order a blood test called PSA to screen men for prostate cancer.
Recent research shows that it is a more accurate screener for infection.
PSA is a chemical found in the prostate. Blood levels rise when a man is infected or has a cancer. When this happens, doctors often stick a needle into the prostate several times, extract tissue and analyze the tissue under a microscope to check for cancer. A study from Belgium shows that almost all biopsies that do not show cancer show infection. If future studies confirm this study, men who have negative biopsies for prostate cancer should then be placed on antibiotics for the many months that it takes to cure prostate infections.
