Dallas Cowboys owner Jerry Jones and head coach Brian Schottenheimer have both revealed their battles with cancer. Jones, diagnosed with stage 4 melanoma in 2010, credits an experimental drug, PD-1, for saving his life after a decade of treatment that included surgeries on his lungs and lymph nodes. Schottenheimer battled thyroid cancer in 2002. Both have since become cancer-free and are using their experiences to inspire others.
