New ways to test for prostate cancer

PSA tends to increase as men get older, but levels that get too high may suggest prostate cancer. Many doctors consider a total PSA level higher than 10 ng/mL (nanograms per milliliter) as the threshold for getting a biopsy to check for cancer. But men with levels between 4 ng/mL and 10 ng/mL have to decide with their doctors whether to go forward with a biopsy or monitor their condition. Nowadays, men with mild to moderately elevated PSA levels can get additional noninvasive tests that can help with the decision process.
