But if it does, that could be bad news for a world where obesity is on the rise. According to the World Health Organization, about 500 million people worldwide are obese; colon cancer killed more than half a million people worldwide in 2008, the most recent figures from the WHO show. For the new research, Ashrafian and his colleagues analyzed data from 23 studies involving more than 100,000 people across the U.S., Asia and Europe, looking at the relationship between polyps and body mass index, or BMI, a measure of weight relative to height. All the studies followed World Health Organization guidelines that define people with a BMI over 25 as overweight and above 30 as obese. In most studies, polyps were identified during colonoscopy procedures in which a flexible tube tipped with a camera is guided though the rectum and into the colon. Self-reported questionnaires were used in two large studies. Overall, researchers found that 22 percent of overweight and obese people had colon polyps, compared to 19 percent in people of normal weight, and the polyp risk grew with increasing BMI. “The findings suggest that obesity may be having an effect (on cancer development) much earlier than we thought,” said Ashrafian. Most polyps don’t cause any symptoms so they are usually not picked up before routine colonoscopy. During the procedure, the doctor cuts out polyps if there are any to make sure they don’t turn into cancer. In their report, published in the American Journal of Gastroenterology, the authors recommend timely colon cancer screening among overweight and obese people. The U.S. Preventative Services Task Force, a government-funded expert panel, recommends colon cancer screening for people ages 50 to 75 (there are a number of different tests, including a cheap stool test, to choose from). In the UK, screening for colon cancer is offered by the National Health Service from age 60 to 69. The new study points to a need for screening that specifically targets obese people, said Dr. Joseph Anderson from Dartmouth in Hanover, New Hampshire, who was not involved in the study.
