Hello and welcome to HCM. One of the most common causes of Bright red blood in the stool are hemorrhoids. This is a benign condition meaning not cancer. If hemorrhoids are external, you would feel lumps around your anus - where you clean yourself after a bowel movement and likely there would be some discomfort associated with the bleeding. If hemorrhoids are internal they do not hurt when you bleed. (internal hemorrhoids are in your distal rectum, which ends with anus. Rectum is the last part of the colon) Another frequent cause of rectal bleeding is hard stool/constipation - sharp edges of dried lumps of stool can damage the rectal mucosa and cause bleeding. There are many other conditions of the colon which can cause bleeding per rectum - which means bleeding from your rectum - these would include inflammatory diseases of the colon called colitis , diverticulosis of the colon or even cancer of the colon. With colitis you would likely have other abdominal symptoms. Diverticulosis may have no other symptoms except bleeding until there is diverticulitis which is and acute illness with infection/inflammation of the diverticuli. Cancer is not likely. A general doctor is able to do initial history taking and work up to determine the most likely cause of your rectal bleeding. Based on the answers you will provide him/her and on the findings of physical exam (including rectal exam) he/she will either decide on the treatment or will have you take more tests like colonoscopy. Hope I answered your question. Regards and best of health.
