Lipoma

What it is:

A non-cancerous growth of fatty tissue cells that can develop in almost any organ of the body, although they are most commonly found just below the skin. Lipomas are very common, grow slowly and are not painful. Generally, lipomas do not require treatment; however, they can be removed with a small skin incision under local anesthesia.

Excision:
The doctor may cut out the lipoma in rare situations.
