Dr. Fen Xia, UAMS Department of Radiation Oncology, and members of Radiation Oncology sign the final beam for the new $65 million Proton Therapy Center scheduled to be complete in 2023, the state’s first and one of only 40 nationwide. Proton therapy uses high-energy beams to target tumors in hard-to-reach areas without damaging surrounding tissue. The center is being built in partnership with Arkansas Children’s Hospital, Baptist Health, and Proton International.
