A proud mother and passionate fitness enthusiast, Jill Stewart, 43, passed away last Friday (July 14) after a nearly 14-month battle with liposarcoma.

Confirmimg the tragic loss via social media over the weekend, Adam Stewart indicated that her transition was peaceful as she was surronded by her husband, three children and other members of the family.

But what is liposarcoma?

Our Today presents some facts on the disease:

Liposarcoma was first discovered in 1857 by German pathologist Rudolph Virchow, who described a tumor arising from fat tissue.

It is a rare, malignant cancer, presenting as tumors from fat tissue that occur in the “soft tissues” of the body.

According to the Massachusetts-based National Organization for Rare Disorders (NORD), liposarcoma is designated malignant due to its potential to recur and spread elsewhere in the body.

The cancer can manifest itself throughout the body; liposarcoma is commonly found within the thigh area or other anatomical extremities. Scientists suggest it is more common in middle-aged males from 50 – 65 years of age compared to women, and very rare in children.

While the specific genetic cause of liposarcoma has yet to be identified, some studies have proposed its genesis ties with fat cells that lose their ability to mature or have unregulated growth.

The mainstay of treatment, NORD continued, is surgery or chemotherapy/radiation, depending on what stage tumors would have reached at presentation.

There are five subtypes—well differentiated (adipocytic, sclerosing, and inflammatory), dedifferentiated, myxoid, round cell, pleomorphic—each of which pose varying levels of disease severity based on the presenting stage of the primary tumor.
