A small lump on the small intestine may be polyps or tumors. 1. Polyp: if there is a lump on the small intestine, it is generally considered to be a polyp, which can be left unprocessed for the time being and reviewed regularly; if there are intestinal symptoms, it can be considered to be resected under the colonoscopy, and after the operation, it is necessary to strictly control the bad dietary habits, and to avoid spicy and stimulating food. 2. Tumor: If it is benign tumor, it will be treated the same as polyp; if it is malignant tumor, no matter it has symptoms or not and its size, it should be resected and pathologically typed in order to guide the next treatment plan. Therefore, when there is a small lump on the small intestine, the doctor can often remove the lump and do a biopsy directly under the colonoscopy, and then decide the treatment plan according to the biopsy results.
