Previous studies have made the connection between obesity and colon cancer, a link recognized by the US National Cancer Institute. But the current study, which appeared in the American Journal of Gastroenterology, is the first to point to a higher risk of colon polyps – also known as adenomas – in heavy people. “Because there is a known association between obesity and cancer, there is a logical extension to expect a connection between obesity and the step before cancer, which is adenoma,”said Hutan Ashrafian from Imperial College, London, who co-authored the study. Ashrafian and his colleagues analyzed data from 23 studies involving more than 100,000 people across the United States, 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 (WHO) 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 while two large studies used self-reported questionnaires. Overall, researchers found that 22 per cent of overweight and obese people had colon polyps, compared to 19 per cent in people of normal weight. 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, who with his fellow authors recommended timely colon cancer screening for overweight and obese people. The findings couldn’t say whether obesity causes polyps by itself, but if it does, that may 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, WHO figures show. Publication:
Aramis Ramirez has polyp removed from colon
Jones threw a bullpen session at 80 percent effort on Sunday and stepped up his intensity in another mound workout on Wednesday. He should be 100 percent for the start of the 2014 regular season and is the favorite right now to take over as the White Sox closer. Carl Pavano retires from baseball at age 38 Carl Pavano has retired from professional baseball. Pavano’s agent shared that news Wednesday with Jeff Todd of MLB Trade Rumors. “Despite my strong desire to compete and hard work in preparing for the upcoming season,” the 38-year-old right-hander said in a statement, “I feel that the amount of time lost from my spleen injury, coupled with the recovery from my complications from that injury, preclude me from continuing to compete at my highest level, which is necessary to perform in the major leagues.” He registered a 4.39 career ERA in 14 big league seasons. Red Sox not actively engaged with SS Drew According to WEEI’s Alex Speier, the Red Sox are not engaged in active discussions with Stephen Drew. Both the Cactus League and Grapefruit League got underway on Wednesday, and yet Drew remains unsigned. He’s struggling to attract offers because his free agency is tied to draft pick compensation and there’s been talk of him waiting until the early part of the summer to settle on a landing spot. Nelson Cruz, who was also tied to draft pick compensation, recently agreed to a one-year, $8 million deal with the Orioles.
