When 12-year-old Ryan Mackey felt a sharp cramp in his left leg in early March, he had no idea he was about to embark upon an unpredictable journey, becoming one of approximately 200 children and teens in the United States each year diagnosed with Ewing’s Sarcoma — a type of tumor that forms in bone or soft tissue.

Ryan’s mother, Uniformed Public Health Service Capt. Megan Mackey, who coincidentally works as a nurse practitioner specializing in radiation oncology at the National Institutes of Health, recognized her son’s symptoms as problematic and scheduled a medical visit at Walter Reed National Military Medical Center. Following a series of x-rays and an MRI , the Mackeys met with U.S. Army Lt. Col. (Dr.) Benjamin K. Potter, who completed his residency training in orthopedic surgery in 2007 at Walter Reed.
