Jones told the Dallas Morning News the initial diagnosis came in 2010. Over the next 10 years he had four surgeries, two on his lungs and two on his lymph nodes. He credited the experimental drug PD-1 — short for Programmed Cell Death Protein 1 — for his recovery.

“I was saved by a fabulous treatment and great doctors and a real miracle [drug] called PD-1 [therapy],” Jones said, via the Morning News. “I went into trials for that PD-1 and it has been one of the great medicines."
