Link to obesity and cancer studies
Weight-loss surgery may help obese women lower their risk of developing cancer, according to a study conducted by Swedish researchers. They found women who had weight-loss surgery were 42% 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 oestrogen, they said, or simply because fewer men get weight-loss surgery.
Obesity has long been known to raise the risk of cancer and the evidence continues to mount. Another study in the Journal of the American Medical Association found people who were obese as young adults had twice the risk of developing pancreatic cancer.
Weight-loss operations in which doctors change the digestive system’s anatomy to cut the volume of food a person can eat, have been shown to reverse diabetes and reduce the risks of dying from heart disease.
