A new blood test called lsoPSA is more accurate than the PSA test, which measures levels of a blood protein called prostate specific antigen, at finding prostate cancer and detecting more advanced cancer, according to preliminary research.

While PSA levels are elevated in men with prostate center, PSA also can climb if a man has a benign condition, such as an inflamed or enlarge prostate., leading to unnecessary procedures including a biopsy.  By contrast,  the IsoPSA test detects structural changes in PSA protein that are associated with cancer. Though more research is needed, IsoPSA has the potential to slash  the rate of unnecessary biopsies by almost half, says the researchers.
