Lipoma

Also called Fatty lump

A lipoma is a soft, fatty lump that grows under the skin. It is harmless, usually painless and moves slightly when pressed. Lipomas can appear anywhere but are common on the shoulders, chest, back, arms and neck. They grow slowly and are more common in middle age.

What it is

Most lipomas do not need treatment.

A lipoma can be removed with a small operation if it is painful, getting bigger or in an awkward place.

Common signs

  • A soft, smooth lump under the skin
  • A lump that moves slightly when pressed
  • Usually painless
  • Slow growth

How it is usually diagnosed

  • Examination of the lump
  • Ultrasound or biopsy, if there is any doubt

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Ultrasound reports
  • Notes on removal, if done

Questions to ask your doctor

  • Is it definitely a lipoma?
  • Should it be removed?
  • What changes should I watch for?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • A lump that grows quickly, is hard, painful or bigger than 5cm, or comes back after removal: get it checked soon
