In early 1998, Prine was diagnosed with squamous cell cancer on the right side of his neck. He had major surgery to remove a substantial amount of diseased tissue, followed by six weeks of radiation therapy.[36] The surgery removed a piece of his neck and severed a few nerves in his tongue, while the radiation damaged some salivary glands. A year of recuperation and speech therapy was necessary before he could perform again.[37] The operation altered his vocals, and added a gravelly tone to his voice.[38]
In 2013, Prine underwent surgery to remove cancer in his left lung. After the surgery, a physical therapist put him through an unusual workout to build stamina: Prine was required to run up and down his house stairs, grab his guitar while still out of breath and sing two songs. Six months later, he was touring again.[37]
All this and Corona got him. So sad
