What is a Lipoma?

Hi,
A lipoma is a benign fatty growth. In certain areas, they can cause cosmetic concerns or pain, but if you don't have symptoms, you don't need surgery to remove the lipoma.

A lipoma is a collection of fat (adipose) cells that form into a mass or lump under the skin. These can at times be tender or painful, and often tend to enlarge or grow over time. In almost all cases, they are a benign growth, with a malignant lipoma, known as a liposarcoma, being an extremely rare entity.

Lipomas are benign fatty tumors composed of a collection of fat cells that only know how to grow, generally very slowly, independent of your weight. Multiple lipomas can be familial. Rarely, a malignant tumor, called a liposarcoma, may mimic one of these- but tend to grow fast and relatively large. If concerned see your physician or surgeon
