Weight Loss Surgery Cuts Cancer Risk

For those who are morbidly obese bariatric surgery causes a large cut in cancer risk.

Montreal, 19 June 2008 Successful bariatric surgery allows morbidly obese patients to lose up to 70 percent of their excess weight and to maintain weight loss. The latest study by Dr. Nicolas Christou of the McGill University Health Centre (MUHC) and McGill University shows that this surgery also decreases the risk of developing cancer by up to 80 percent. Dr. Christou presented his preliminary results yesterday at the 25th Annual Meeting of the American Society for Metabolic & Bariatric Surgery.

The researchers compared 1,035 morbidly obese patients who underwent bariatric surgery at the MUHC between 1986 and 2002 with 5,746 patients with the same weight profile who did not undergo the operation. The number of cancer diagnoses in first group was 85 percent lower for breast cancer and 70 percent lower for colon and pancreatic cancers, and was also distinctly lower for several other types of cancer.

"The relationship between obesity and many forms of cancer is well established," said Dr. Christou. "This is one of the first studies to suggest that bariatric surgery might prevent the risk of cancer for a significant percentage of morbidly obese people."

Grrrr. It's not obesity and cancer that is the link. It's hyperinsulinemia via IGF and cancer. Bariatric surgery severs the neurolink to the pancreas which causes an instantaneous reversion of hyperinsulinemia/metabolic synd/diabetes and thus the cancer drop.
