Lipomas have no known cause. They may be related to a previous injury to the tissue.

Risk Factors

Factors that may increase your chance of a lipoma include:

  • Family history
  • Lipomatosis, a hereditary condition that results in lipomas all over the body
  • Adiposis dolorosa, a rare condition that results in painful lipomas


Lipomas are usually soft, painless, moveable lumps under the skin. They usually don't cause symptoms.


Your doctor will ask about your symptoms and medical history. A physical exam will be done. The diagnosis is usually based on smoothness, softness, and ease of movement under the skin. Your doctor may do a biopsy to rule out other skin conditions.


Talk with your doctor about the best treatment plan for you. You may want to leave the lump alone. Treatment options include:

  • Injections to reduce the size of the lipoma
  • Laser treatment (given under the skin) to remove the lipoma
  • Surgical excision—lipomas are cut out
  • Liposuction—removes excess fat from under the skin


There are no current guidelines to prevent lipoma.

The best chance of surviving a heart attack is to act quickly. Do not wait for symptoms to go away. Call 9-1-1 immediately, and chew an aspirin while waiting for the ambulance to arrive.
