Richard J. Ablin

Richard J. Ablin is an American scientist and physician known for discovering the prostate-specific antigen (PSA) in 1970. PSA is a protein produced by the prostate gland, and its presence in the blood can help detect prostate cancer. Ablin’s work significantly contributed to prostate cancer screening and diagnosis, although he has expressed concerns about the overuse of PSA testing, which can lead to unnecessary treatments. His research has been influential in urology and cancer detection, balancing the benefits of early diagnosis with awareness of potential limitations and risks associated with PSA testing.
