Sweden: For Women With Obesity, Risk for Breast Cancer Drops After Bariatric Surgery

For women with obesity, the risk for breast cancer is reduced after bariatric surgery, according to a study published online May 15 in JAMA Surgery.

Felipe M. Kristensson, M.D., from the Sahlgrenska Academy at the University of Gothenburg in Sweden, and colleagues examined whether bariatric surgery is associated with breast cancer incidence in women and whether the benefit is modified by baseline insulin level in the Swedish Obese Subjects study. The study included 2,867 women aged 37 to 60 years with a body mass index of 38 kg/m2 or greater. A total of 1,420 women underwent surgery and 1,447 contemporaneous matched controls received usual obesity care.
