A Revolutionary Treatment That Attacks The Cancer, Not The Patient.
Proton therapy is a next-generation radiation treatment that precisely targets tumors, minimizing radiation to healthy tissue and improving the lives of patients with cancer. Proton therapy deposits the greatest amount of radiation right into the tumor and then stops, allowing patients to receive high doses with less risk of damage to nearby healthy tissue. This more targeted form of radiation is especially useful for pediatric cancers, where the impact of excess, harmful radiation causes long-term damage. Research shows proton therapy can minimize short- and long-term side effects, reduce the occurrence of secondary tumors and improve patients’ quality of life.
