Lipomas are benign tumors formed by mature fat cells, and the only correct and effective way to remove them is by surgical excision. If the lipoma is small, observation can also be considered. 1. Surgical excision: all lipomas can only be removed by surgery. After surgery, it is necessary to do pathological examination routinely to exclude malignant changes, and apply pressure bandage to the local area, which can prevent postoperative bleeding and accumulation of fluid. After surgery, it is necessary to keep the incision dry and clean to prevent infection, and it is also necessary to follow the doctor’s instruction to change the medicine regularly. 2. Observation: not all lipomas need direct surgical resection. If the lipoma is small, less than 1cm in diameter, it usually does not need special treatment, close observation and regular review. It should be noted that if the size of the lipoma increases rapidly in a short period of time, or the incision after surgery shows symptoms such as pain, redness, swelling, bleeding, etc., it is recommended to go to the hospital in time for consultation.
