The prognosis for liposarcoma, depending on its stage, is between 90 and 56 percent five years after diagnosis, according to the American Cancer Society. Liposarcoma is classified as a type of soft tissue sarcoma, cancer that affects fat cells, muscle, nerves, fibrous tissues, blood vessels or deep skin tissues.
Liposarcoma is a soft tissue sarcoma that develops in the body's fat cells, according to the American Cancer Society. It primarily affects individuals between the ages of 50 and 65. It is also represents 3 percent of childhood cancers, according to Dana-Farber Cancer Institute. A liposarcoma tumor can develop anywhere in the body, but it is primarily found behind the knee, at the back of the abdomen or in the thigh.
Most tumors do not spread outside of their original locations, Dana-Farber explains. Surgery to remove the tumor and the surrounding tissue around it is a common treatment, sometimes followed up with radiation. If the cancer is aggressive in a leg or arm, the limb may need to be amputated.
Although doctors don't know exactly what causes liposarcoma, studies have found genetic links, and some research points to other cancers causing soft tissue sarcomas such as liposarcoma, notes Dana-Farber Cancer Institute. Epstein-Barr patients also have a higher likelihood of developing the condition.
