If I had a colonoscopy 10 months ago and everything was fine, it would definitely not be cancer now. Don't worry. From what you said, I think it's intestinal dysfunction. You can take this medicine and check it out: Trimebutin Maleate Tablets: 1 tablet 3 times a day, take Beficon half an hour before meals, 3 tablets 3 times a day, take after meals (note that this medicine should be kept in the refrigerator It will be invalid if it is not kept fresh). Eat it for a few days and see.
