What is liposarcoma? 

Liposarcoma is a malignant soft tissue tumor that develops in fat tissue. It’s most often found in the abdominal cavity or extremities, usually the thigh or upper arm, but it can be found anywhere in the body. Liposarcoma tumors can exist for a long time before they are discovered and does not usually spread beyond its local location. The cause of this tumor is unknown but has been linked to genetics and inherited diseases. Liposarcoma is very rare in children, and is much more likely to occur in an adult. 

The three primary subtypes of liposarcoma include well-differentiated (low-grade tumors that may recur locally but don’t spread), myxoid and pleomorphic, which are aggressive and highly-malignant.
