A lipoma is slow-growing, benign growth of fat cells. It is contained in a thin, fibrous capsule and found right under the skin. A lipoma is typically not tender and moves around easily with slight pressure.
A lipoma is not cancerous and treatment generally is not necessary. There is also a condition called familial lipomatosus, where people develop multiple lipomas, especially on the arms and legs, and other family members have these growths as well.
If the lipoma is on a pressure-bearing area, it may create discomfort and this is when people seek removal. People also request removal because they don’t like the appearance of these bumps. Often a small incision can be made over the lipoma and they can be “popped” out easily. This is a simple in-office surgical procedure under local anesthesia.
