Lipomas are very common. They appear as smooth, soft lumps under the skin. Lipomas range in firmness, and some feel rather hard. The skin over the lipoma has a normal appearance. They can develop anywhere on the body but are particularly common on the forearms, torso, and neck. Lipomas are more common among women. Some people have only one, but other people develop many lipomas. Multiple lipomas may run in families and be part of a genetic condition (for example, familiar multiple lipomatosis). Lipomas rarely cause problems, although they may occasionally be tender or painful.

Usually, a doctor can easily recognize lipomas, and no tests are required for diagnosis. Lipomas are not a form of cancer and they rarely become cancerous. If a lipoma begins to change in any way or is large, a doctor may do a biopsy (removal of a tissue sample for examination under a microscope).
Treatment of lipomas usually is not required, but bothersome lipomas may be removed by surgery or by liposuction (removal of fat with a suction device).
