My friend was just diagnosed with lsmft to the hip bone? can this be triggered by a car accident? what are typical treatment options for this?

LSMFT not traumatic: Liposclerosing myxofibrous tumours (LSMFT), also known as polymorphic fibro-osseous lesions of bone, are rare benign fibro-osseous lesions that have a predilection for the intertrochanteric region of the femur. Trauma is not the cause. Regular follow up is warranted and tumor resection with interval imaging changes or increased symptoms.
