Lipoma overview

Overview
A lipoma is a common, benign tumor composed of fatty tissue. Lipomas are soft to the touch, usually moveable, and are generally painless. They grow very slowly, and in rare cases can become cancerous (Malignant liposarcoma also arises from fatty tissue.) Many lipomas are small but can enlarge to sizes greater than six centimeters. Lipoma is commonly found in adults from 40 to 60 years of age but can also be found in children. Approximately one percent of the general population has a lipoma.
