    Precision

    Capable of delivering a high dose of proton therapy directly to the tumor, precisely sculpted to its complex shape and size.

    Safety

    Ability to spare more healthy tissues: reduces complications, side-effects, and risk of secondary cancer.

    Effectiveness

    A growing body of clinical evidence shows proton therapy to be effective while reducing side-effects for many cancers.

Conventional radiotherapy deposits most of the dose at the entrance and travels past the tumor

Proton therapy deposits most of the dose in the tumor with minimal entrance and no exit dose

Protons deliver most of their energy at a prescribed, programmable distance inside the body, known as the Bragg peak, so a high dose is delivered to the tumor and less to healthy tissue. That means patients may experience fewer side effects, improved long-term outcomes, and enhanced quality of life.

According to the American Society of Clinical Oncology (ASCO), compared with conventional radiotherapy, proton therapy is usually able to deliver 60 percent less radiation to healthy tissue around the target site, while delivering a high dose to the tumor itself.

Effectiveness

Proton therapy is an established form of treatment for many specific indications and is widely accepted by physicians, government agencies, and many insurers. There is a wealth of published data on the efficacy of proton therapy and large numbers of ongoing trials continue to examine its clinical advantages.

Proton therapy is especially well suited for pediatric patients due to the reduced possibility of long-term side effects and secondary cancers. For additional information on the rationale for treating specific disease types with proton therapy, refer to the ACR–ASTRO Practice Parameter for the Performance of Proton Beam Radiation Therapy.
