The probability of colon cancer is slightly higher after gallbladder removal because there is no place to store bile after gallbladder removal, and bile will enter into the intestine continuously. It may also be manifested as frequent bowel movements, thinning of stools, etc. Therefore, patients who have had their gallbladder removed should go to the hospital regularly after the age of 40 to avoid the occurrence of tumors in the colon, usually through anal finger diagnosis and colonoscopy, and if cancer in the colon can be detected early, early surgery is very effective.
