However, as of 2005, only 59 percent of people aged 50 or older had been screened according to these recommendations, and only 50 percent had had a colorectal endoscopy procedure (either sigmoidoscopy or colonoscopy, screening techniques that can both visualize cancer in the colon and rectum and remove precancerous polyps) within the past 10 years.
