Liposarcoma is a rare cancer of connective tissues that resemble fat cells under a microscope. It accounts for up to 18% of all soft tissue sarcomas. Liposarcoma can occur in almost any part of the body, but more than half of liposarcoma cases involve the thigh, and up to a third involve the abdominal cavity.
Liposarcoma tends to affects adults between the ages of 40 and 60. When it does occur in children, it is usually during the teenage years.
There are four types of liposarcoma, each with its own unique characteristics and behaviors.
