LANCASTER – Construction of the future Proton Center at the Penn Medicine Lancaster General Health Ann B. Barshinger Cancer Institute has seen the arrival and installation of a 220-ton cyclotron and related components used to deliver advanced radiation therapy. The cyclotron is the centerpiece of the technology used to treat patients with this most precise form of radiation. The new, state-of-the-art Proton Center in Lancaster marks a new chapter in Penn Medicine’s global leadership in proton therapy, clinical care and research, becoming the health system’s second center to offer the treatment. Proton therapy is perhaps the most advanced treatment for cancer tumors located close to critical organs and highly sensitive areas, such as the spinal cord, heart, and brain. It also provides new options for patients whose cancers can’t be complete removed by surgery, or who have previously received conventional radiation in the same area. Expected to be completed by Summer 2022, it will be the first and only proton therapy center in central PA.
