Lipoma is a very common benign tumor in clinic. Because the pathogenesis or etiology of lipoma is not particularly clear, its prevention is limited. Clinically, losing weight or controlling weight and reducing the intake of high cholesterol and greasy food may reduce the formation of lipoma. At the same time, for some small diffuse lipomas, fitness, exercise and paper-cutting can be considered to reduce the occurrence and development of lipomas. For larger lipomas, surgical methods can also be considered. For example, if the clinical lipoma is larger than 5cm, which affects the appearance or has pain, traditional incision surgery can be performed to completely remove the lipoma with little postoperative recurrence.
