New research indicates that sigmoidoscopy, an alternative to colonoscopy may be more effective for men than women. Flexible sigmoidoscopy does not usually involve sedation and involves only about 1/3 of the colon, compared to colonoscopy. According to a study conducted on almost 99,000 Norwegians aged 50-64, man undergoing sigmoidoscopy rad a 34% lower risk of colon cancer and 37% lower risk of death after 17 years, "however women saw little reduction in their colon cancer risk or death rates compared to women who weren't screened."
