<s>[INST] Hi I have three tumors one behind my stomach and one beside my bowel and one in my grion my heath care team say it s better to watch things they are not benign and not malignant why do they not want to remove them why would theyleave them to see what happens over time [/INST] Hi, Thanks for writing in. It is possible that the benign tumors you have mentioned are probably lipomas or neurofibromas. Both these tumors are soft tissue origin and not likely to become malignant if left untreated. A lipoma is a benign fat containing tumor which slips over the skin. A neurofibroma has nerve tissues and also does not change over time. Such tumors are to be removed only if there is pain or sudden enlargement in size. Should you have apprehension then you might get FNAC or biopsy to be done from one of the swelling to confirm the pathological diagnosis of the swelling? Please closely watch for similar tumors and discuss with your doctor if there is sudden pain or increase in size. Please do not worry. </s>
