A lipoma is a harmless lump of fat. There are several types, usually classified by where they appear. Lipomas may occur anywhere and are commonly found just beneath the skin.
Factors that may increase your chance of a lipoma include:
Lipomas are usually soft, painless, moveable lumps under the skin. They usually don't cause symptoms.
Your doctor will ask about your symptoms and medical history. A physical exam will be done. The diagnosis is usually based on smoothness, softness, and ease of movement under the skin. Your doctor may do a biopsy to rule out other skin conditions.
The lump does not need to be treated. Some may want it removed. Treatment options include:
