Comorbidity must be considered when making recommendations about CRC screening with older patients. In a retrospective study of 404 VA patients over age 75 who underwent colonoscopy and were followed for 5 years, only 8 (2 percent) were diagnosed with colorectal cancer. The majority of patients passed away from other causes. Only age and severity of comorbidity were risk factors for death within 5 years of colonoscopy [3].
General colon cancer screening guidelines for people without Crohn's disease call for a colonoscopy every 10 years beginning at age 50. However, depending on how long you've had Crohn's disease and how much of your colon is involved, you may need a colonoscopy as often as every one to two years. Talk to your doctor about the best colon cancer screening schedule for your particular situation. Dec. 27, 2014 See more In-depth.
