What Are the Differences between Lipoma and Liposarcoma?

Q:
What are the differences between lipoma and liposarcoma?

A:
Nature

Lipoma is a benign tumor that occurs in adipose tissue.

Liposarcoma is a cancer that arises in fat cells in deep soft tissue.

Size

Lipomas are usually small with diameters of about 1–3 cm, but in rare cases they can grow over several years into “giant Lipomas” which are 10–20 cm across and weigh as much as 4–5 kilograms.

Liposarcomas are usually big and grow rapidly

Locations

Lipomas usually occur under the skin, sometimes they may be deeper. Common locations include the upper back, shoulders and abdomen.

Liposarcomas can occur in fat cells in any part of the body, but most occur in the muscles of the limbs or in the abdomen.

Frequently affected groups

Around 2% of the ordinary people have a lipoma. Lipomas are most common in middle age (age from 40 to 60), though they can occur at any age. They are rare in children and males are more often affected than females.

Liposarcomas are most common in people aged 40 and above. Liposarcoma is the second-most common of all soft-tissue sarcomas.

Treatment

Lipoma usually does not require treatment. When the Lipoma bothers you, is painful or is growing, you might take some treatments including:

  • surgical removal
  • liposuction

Treatment of liposarcoma often include:

  • surgical removal
  • radiation
  • chemotherapy

Please remember to consult your doctor about the treatments for your case.
