Sigmoidoscopy Fails To Detect Polyps In Colon Of Two-Thirds Women
Sigmoidoscopy, a technique commonly used to check for colon cancer, fails to show precancerous polyps in two-thirds of women tested, according to a study. Earlier research had already showed a failure rate in men of 30 percent using the technique, which examines the lowest one-fourth of the colon, according to the study financed by the National Cancer Institute.
