Johnson & Johnson is urging surgeons not to use a surgical tool that has been found to spread certain forms of uterine cancer in women, the company said Wednesday. Sales of the company's laparoscopic power morcellators, used during hysterectomies and fibroid-removal surgery, were halted in April because of a warning issued by the Food and Drug Administration. The FDA told members of the medical community that the device could spread a form of uterine cancer called sarcoma in patients, lowering chances of survival.
