Web Desk(October 18, 2017): Weight-loss surgery could help some severely obese people reduce their risk for cancer by at least 33 percent, a new study suggests.
The analysis included data on nearly 22,200 people who had weight-loss surgery between 2005 and 2012, and over 66,400 people who didn’t have the surgery. More than 80 percent of the study participants were women.
The study found that patients who’d had weight-loss surgery, compared with those who had not had the surgery, were one-third less likely to have developed cancer, particularly the types of cancer related to obesity.
However, the study found no significant association between cancer risk and weight-loss surgery among the men in the study.
The researchers pointed out that at least two of the cancers found to be affected by weight-loss surgery only affect women; breast cancer and endometrial cancer.
“What’s surprising is how great the risk of cancer was reduced,” he said. But the study did not prove that weight-loss surgery caused the chances of certain cancers to drop.
While other findings included a 41 percent reduced risk for colon cancer and a 54 percent reduced risk for pancreatic cancer for those who had weight-loss surgery.
The surgery helps prevent diabetes and lower insulin levels, which could lead to a lower risk for pancreatic cancer, according to the researchers.
