Lipoma is a kind of benign tumor, which is mainly divided into superficial lipoma and multiple lipoma. Superficial lipoma is relatively less harmful to human body, but if not treated in time, it may affect the mood and appearance; while multiple lipoma has the risk of cancer, which should be taken seriously. 1. Superficial lipoma: it is a kind of lipoma that occurs on the surface of skin, which is relatively less harmful to human body and generally does not affect health, but some patients may feel inferior because the lipoma grows in a more conspicuous place, which will affect the aesthetics and the patient’s emotion. 2. Multiple lipomas: Multiple lipomas usually develop in deeper areas, and may become cancerous if not treated in time, which will pose great threat to patients’ health. Moreover, this type of lipoma is usually large in size and often accompanied by pain, which greatly affects the quality of life of patients. If lipoma is found, it is recommended to consult a doctor in time to understand the severity and type of the disease, and then treat the symptoms. For patients who need surgery, the tumor should be removed as soon as possible, and a pathologic biopsy should be performed after surgery to rule out malignant lesions.
