1, rectal cancer can also cause bleeding, but generally older, early defecation habits change, you can do colonoscopy and CEA detection to identify.
2. Fistula can also cause bleeding, but there will be pain around the buttocks, so pay attention to it in the early stage.
So according to the information you provided and my years of clinical experience, it is hemorrhoids. I went to an intestinal hospital with good conditions for examination and diagnosis, preferably surgery. I hope it helps you.
