Description: Aggressive treatment of early prostate cancer, and not watchful waiting, improves the survival of older men, a new study suggests. "There has been a belief that watchful waiting was the safest treatment for older men with moderate prostate cancer," said Dr. Yu-Ning Wong, an oncologist at Fox Chase Cancer Center who is lead author of the report in the Dec. 13 issue of the Journal of the American Medical Association. "Our study suggests there may be a survival benefit," Wong said.
