A Swedish study reports that weight loss surgery may cut the risks of cancer for obese women.

Weight-loss surgery cuts cancer risks in women | Health | Reuters reports:

“They found women who had weight-loss surgery were 42 percent less likely to develop cancer during a 10-year study published in the journal Lancet Oncology.

Men in the study did not benefit, possibly because many cancers are driven by female hormones such as estrogen, they said, or simply because fewer men get weight-loss surgery.”
