Proton Therapy


Proton therapy is an advanced form of radiation therapy that is currently in use at the Roberts Proton Therapy Center at Penn. Protons are different from conventional radiation because the beam can deposit the bulk of the radiation in the target and significantly reduce normal tissue exposure to excess radiation. There is significant potential to reduce side effects and improve overall outcomes. For some tumors, higher doses of radiation may be delivered with protons and there is also the potential to improve combination treatment with other therapies, such as chemotherapy, which can be difficulty with conventional radiation therapy. As with all cancer therapies, protons should not be used for everything. They are a tool that may be of benefit for particular tumors and particular situations. The following sections will help explain both the promise and limitations of this technology.
