New research shows consuming higher doses of aspirin may reduce the risk of colon polyps, which can develop into cancer.
Researchers studied about 27,000 women between 34 and 77 years old. The participants underwent endoscopic colon exams between 1980 and 1998. During the 18 years, nearly 1,400 of the women were diagnosed with adenoma, a type of polyp known to be precancerous.
AdvertisementResults show participants who reported taking aspirin regularly were 25-percent less likely to have adenoma than those who did not take aspirin. Women who had the lowest risk of developing polyps reported taking more than two aspirins per day. Researchers say current guidelines suggest low doses (one small tablet) of aspirin are as effective as higher doses for heart disease prevention. High doses of aspirin are associated with a greater risk of side effects such as internal bleeding.
Despite the encouraging results, researchers say more studies are needed to confirm their findings and determine the safest dose. Researchers say until their findings are confirmed, people should follow the current guidelines for aspirin consumption.
