Although every medical procedure carries inherent risks, colonoscopies are routinely performed with a well-established safety record. The benefits of undergoing a colonoscopy for the early detection of colon or colorectal cancer significantly outweigh the potential complications. Following a colonoscopy, some individuals may experience sensations of cramping or bloating. Additionally, there is a possibility of observing blood either in your rectum or in your stool post-procedure. Such occurrences typically occur when a tissue sample is obtained, or a polyp is removed during the colonoscopy. However, in the majority of cases, any side effects or risks associated with a colonoscopy are minimal.
