Weight loss surgery reduces colon cancer risk Individuals who are obese are at a 34% greater risk of developing colon cancer compared to other people. According to a French study, though obesity increases the colon cancer risk, weight-loss surgery can help reduce the risk. Therefore, the people aged between 50 and 75 years need to undergo a regular screening test for colorectal cancer as they are at an increased risk.

The study analyzed data from over 1 million obese people aged between 50 and 75 years, collected between the years, 2009 and 2018. During the 5 years of the follow-up period, more than 13,000 people were diagnosed with colon or rectal cancer. The study findings revealed that the colorectal cancer rate was 0.6% among those who underwent weight-loss surgery and the rate of colorectal cancer was almost double or 1.3% among those who did not undergo surgery. It was also found that fewer cases of colorectal cancer were diagnosed after weight-loss surgical procedures such as gastric bypass and sleeve gastrectomy.

Weight-Loss Surgical Interventions May Be Chosen Based on Preference

Weight-loss surgery is performed to create a small stomach so that the patients feel full fast and eat less amount of food. Those who want to consider weight loss should do so after considering the options available and their personal preferences. In gastric banding surgical procedure, a band made of silicone will be placed at the top of the stomach to reduce its size. With the gastric bypass procedure, the stomach will be stapled smaller and then connected to the small intestine. In the sleeve gastrectomy procedure, nearly 80% of stomach removal will be done.

Early research also suggests that obese individuals should lose at least 20% of their weight to reduce the risk of cancer and get the best outcome. Weight-loss surgery is the best possible way to lose weight and accomplish this.

Losing Weight Through Surgery Is a Good Choice to Reduce Cancer Risks
