Study fails to link vasectomy to cancer
By Nathan Seppa
A medical riddle that arose more than a decade ago is now closer to resolution. Three studies in the early 1990s suggested that men who had undergone vasectomy seemed more apt to get prostate cancer than were men who hadn’t had the procedure. Other studies found no connection, but uncertainty has lingered.
Researchers in New Zealand report in the June 19 Journal of the American Medical Association that men with prostate cancer are no more likely to have had a vasectomy than healthy men are.
