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].
Medical guidelines call for a repeat test 10 years after the first negative colonoscopy, but their study found that nearly half of patients with negative colonoscopies had another in less than seven years, often within three or five.About a quarter took place without any clear medical indication.ut you may not hear much about when colon cancer screening should stop. Even the Fight Colorectal Cancer Web site, from the major advocacy group working to make Americans aware of the disease and its prevention, says that all adults over age 50 should be screened. âDonât wait. Talk to your doctor,â it urges.
