Lipoma: Causes, Symptoms, Diagnosis & Treatment A lipoma is a non-cancerous (benign) fatty lump that develops just beneath the skin. It is usually soft, slow-growing, and painless. Lipomas are common and mostly harmless.

What Is a Lipoma?

A lipoma consists of fat cells enclosed in a thin capsule. It can occur anywhere on the body, but is most commonly found on the neck, shoulders, back, arms, and thighs. If you are interested in learning about other benign tumors, you may find our related article helpful.
