Actress Angelina Jolie recently announced that she underwent a preventive double mastectomy after learning that she was genetically predisposed to cancer. Her disclosure was a powerful show of solidarity with the more than 100,000 American women who undergo breast removal surgery each year.
But Jolie’s story, while inspirational, is different from most women’s. She benefited from a relatively uncommon nipple-sparing mastectomy (NSM), a procedure that removes the breast tissue while preserving the breast skin and nipple. With NSM, after reconstructive surgery, breasts are left looking mostly unchanged.
