Abstract:
Colorectal cancer and precancerous adenomas disproportionately affect the elderly, necessitating the need for screening and surveillance in this group. However, screening and surveillance decisions in the elderly can be challenging. Special considerations such as comorbid medical conditions, functional status, and cognitive ability play a role in one's decisions regarding the utility of screening and surveillance as well as the success and safety of various screening modalities. This article explores the evidence for screening and surveillance in the elderly, and addresses key challenges unique to this population.
