Lipomas consist of fatty tissue and feel like a soft, somewhat rubbery lump.
They can be located in most regions of the body, and are often seen in the neck, back, chest and thighs. Lipomas rarely cause pain or other discomfort.
The cause of lipomas is unknown. Genetics may play a role.
Lipomas do not need treatment, but they can be surgically removed if desired and indicated. It is usually sufficient to make a single incision through the skin, in order to "peel out" the lipoma (it is not stuck in the surrounding tissue). The operation is performed under local anesthetic and leaves a line-shaped scar.
