Lipomas belong to superficial tumors and are categorized as benign. They are caused by the proliferation of subcutaneous adipose tissue. If treatment is desired, surgery is an option. Medication or other treatments are ineffective. If the lipoma is small, it can be surgically removed in an outpatient setting, typically under local anesthesia. For a larger lipoma, it is recommended that the patient be hospitalized for surgery, which involves intravenous anesthesia combined with local anesthesia to remove the lipoma.
