Meanwhile in the U.S., the Mayo Clinic broke ground on its second proton beam facility in Arizona on Tuesday. Only nine other proton centers in the nation are currently operational, though seven more are in development. “Right now we’re just trying to get our heads around the protons,” said Chair of Radiation Oncology at the Mayo Clinic in Arizona Steven E. Schild about the Arizona facility. No carbon ion treatment centers exist yet in the U.S., though Schild said they’ve been thinking of adding that technology at the Mayo Clinic.
