Lipoma is a kind of benign tumor formed by fat accumulation, it may become malignant, but the chance of malignant change is very low, so don’t be too anxious. Most of the lipomas are caused by changes in the metabolic function of the body. Generally, a relatively mild lipoma does not have the possibility of cancer, and if there is no dysfunction and no painful symptoms, surgery is not necessary. If the tumor is painful, affects the function, or is significantly enlarged, it needs to be removed surgically, and then pathological examination will be done to determine the next treatment plan according to the pathological examination results. In addition, if the lipoma is caused by family history, there is a higher possibility of cancer in this case, so extra attention is needed. For patients who have lipoma surgically removed, smoking and alcohol should be banned after surgery, and more high-protein foods such as fish and shrimp should be eaten to help the wound heal, and patients should not eat spicy and stimulating foods.
