Testosterone Treatment Linked With Prostate Cancer
Prostate cancer developed in 20 men within months to a few years after they began testosterone supplementation to correct a deficiency of the hormone, investigators report. "There are several anecdotal case reports, small studies, and observational studies like ours which raise concern but do not provide conclusive evidence yet," Dr. Franklin D. Gaylis told Reuters Health. The issue is a concern because prostate cancer is usually driven by testosterone. Gaylis, from the University of California at San Diego Medical Center, and colleagues report this series of patients "in whom clinically significant prostate cancer developed and was presumed to be related to exogenous testosterone use," in the Journal of Urology.
