A large study showed that for most patients, having both breasts removed after cancer was detected in one made no difference.<\/p>\n

For the more than 310,000 women<\/a> diagnosed with breast cancer every year, no matter how well the treatment goes, there is always a lingering fear. Could the disease come back, even years later? And what if it comes back in the other breast? Could they protect themselves today by having a double mastectomy?<\/p>\n

A study has concluded that there is no survival advantage to having the other breast removed. Women who had a lumpectomy or a mastectomy and kept their other breast did just as well as women who had a double mastectomy, Dr. Steven Narod of Women\u2019s College Hospital in Toronto and his colleagues reported, using U.S. data from more than 661,000 women with breast cancer on one side.<\/p>\n

In the study, published in JAMA Oncology on Thursday<\/a>, the researchers added that most women did very well \u2014 the chance of cancer in the other breast was about 7 percent over 20 years.<\/p>\n

But the study\u2019s results may not apply to women who have a gene variant, BRCA1 or BRCA2, which greatly increases their cancer risk. For the 1 in 500 American women<\/a> with this variant, cancer researchers agree that it\u2019s worth considering<\/a> a double mastectomy.<\/p>\n<\/div>\n<\/div>\n

The finding that a double mastectomy is not protective against death for many breast cancers seems counterintuitive, Dr. Narod admitted. An accompanying editorial, by Dr. Seema Ahsan Khan, a breast cancer surgeon at Northwestern University, and Masha Kocherginsky, a biostatistician also at Northwestern, called it a conundrum.<\/p>\n

Previous smaller studies have come to the same conclusion. But, Dr. Narod said, some doctors have questioned the methods in earlier research. <\/p>\n
