Lipoma is a common tumor of the body surface. The pathogenesis is partly due to disorders of fat metabolism in the liver. We often see a large proportion of patients who often drink a lot of alcohol, suffer from hepatitis, fatty liver and rapid weight gain, and some of the causes are not clear. Part of the cause is due to excess nutrition and little activity. Clinical manifestations: The clinical manifestations of benign lipoma in general are single or multiple, painless masses, slow development, no pressure pain, less clear boundaries, lobulated, less active, may adhere to and protrude from the skin. Treatment: We need to cultivate a healthy lifestyle, treat fatty liver and drink less alcohol. Eat a lighter diet and be more active. Climb mountains, exercise. It’s all about keeping your mouth shut and your legs open. Surgery is only considered when it affects working life, when the tumor is huge, and when there is a possibility of suspicion of malignancy. You need to know whether it is fibroid, fibrosarcoma, liposarcoma, etc. Pathological examination must be done after surgery.
