A lipoma is a growth of fatty tissue that slowly develops just under your skin. People of any age can develop a lipoma, but children rarely develop them. While a lipoma can form on any part of the body, they typically appear on the neck, shoulders, back, abdomen, arms, and thighs. They are classified as benign growths (tumors) of fatty tissue; this means a lipoma is not cancerous and is rarely harmful.
