The surgical removal of abdominal fat resulted in 75-80 percent fewer UV-induced skin cancers among obese mice fed a high-fat diet. When it comes to humans, scientists can’t say if liposuction or other fat removal procedures are beneficial for treating obesity and reducing the risk of cancer. Although they know that obesity increases the risk of heart disease, diabetes, and cancer, there have not been clinical studies to determine if the surgical removal of fat tissue would decrease cancer risk in humans.
