Richard J. Ablin is an American research scientist and professor who is known for his discovery of prostate-specific antigen (PSA). He was born on July 19, 1935, in New York City, USA.

Key Contributions and Achievements:

1. Discovery of Prostate-Specific Antigen (PSA): Richard J. Ablin, along with his research team, discovered PSA in 1970. PSA is a protein produced by the prostate gland and is commonly used as a biomarker for prostate cancer detection and monitoring.
2. PSA as a Cancer Marker: Ablin’s discovery of PSA revolutionized prostate cancer diagnosis and management. PSA testing has become a standard screening tool for prostate cancer, aiding in early detection and guiding treatment decisions.
3. Prostate Cancer Awareness: Ablin has been an advocate for informed decision-making regarding PSA testing, cautioning against its overuse and the potential for false positives leading to unnecessary medical interventions.
4. Academic Career: Richard J. Ablin has had a distinguished academic career, serving as a professor in the Department of Pathology at the University of Arizona College of Medicine.
5. Research and Publications: Ablin has authored numerous research papers and publications, focusing on cancer biology, immunology, and the role of PSA in prostate cancer.
6. Advocacy and Education: Ablin has been involved in raising awareness about prostate cancer and promoting education about the limitations and controversies surrounding PSA testing.

Richard J. Ablin’s discovery of PSA has had a profound impact on prostate cancer diagnosis and treatment. While PSA testing has been valuable in identifying potential prostate cancer cases, its use has also generated debates about the risks of overdiagnosis and overtreatment. Ablin’s contributions have played a critical role in advancing our understanding of prostate cancer and have stimulated ongoing discussions in the medical community about the appropriate use of PSA testing.
