GALVESTON, Texas, Oct. 5 (UPI) -- Researchers found in a recent study that testosterone therapy for over a five-year period did not increase the risk for aggressive prostate cancer, nor did the number of injections increase the risk of developing the disease.
Prostate cancer generally is a slow-growing disease, however researchers mounted the study based on concerns by doctors and a lack of research in the area for patients who'd been on testosterone therapy for more than a year.
