Vasectomy Linked To Increased Risk Of Prostate Cancer
Vasectomy is a common form of contraception in the U.S., with about 15% of men having the procedure. Prostate cancer is the second-leading cause of cancer death among U.S. men, so identifying risk factors for lethal prostate cancer is important for public health. A new study by researchers from the Harvard School of Public Health found that vasectomy was associated with a small increased risk of prostate cancer but a stronger risk for advanced or lethal prostate cancer. The association remained even among men who received regular PSA screening, suggesting the increased risk of lethal cancer cannot be explained by diagnostic bias. This was the largest and most comprehensive study to date to look at the link between vasectomy and prostate cancer. read more
