or tumor,
tissue composed of cells that grow in an abnormal way. Normal tissue is growth-limited, i.e., cell reproduction is equal to cell death. Feedback controls limit cell division after a certain number of cells have developed, allowing for tissue repair

a limited benign tumor (sometimes multiple) consisting of fatty tissue.

Lipomas generally develop on the back, neck, and anterior abdominal wall. They vary in density and in size, from that of a hazelnut to that of the head of a grown man. Lipomas usually do not impair any function; generally, they are removed for cosmetic reasons.


A benign tumor composed of fat cells.
