I am seeking treatment options for my 44 year-old sister. Who was diagnosed with a high grade leiomyosarcoma of the lower extremity a year and a half ago.It was removed using a wide excision and followed with radiation. It has now traveled to both sides of her lungs. The largest tumor is close to her aorta. We are still waiting for the path results on the lung biopsy but assume it is probably the leiomyosarcoma again. Please help she has two small children.
