When the results came in, it was confirmed that Ross had sarcoma, a type of cancer that develops from certain tissues, like bone or muscle. The first sarcoma specialist Ross met with in Metro Detroit came up with a treatment plan that caught Ross off guard. Though Mott said the surgery could leave Ross leg permanently stiff and unable to bend, she had gained 75% mobility less than a year later. But five years after her initial diagnosis, Ross sarcoma returned in her hip. The surgery was a success, but at a follow-up appointment, Ross told Mott she was experiencing pain on the right side of her spine.
