Precise Cancer Treatment

What is Proton Therapy?

Proton therapy is an advanced form of external-beam radiation therapy used to treat cancer. Proton beams are directed at tumors, delivering targeted radiation that destroys cancer cells while minimizing exposure to surrounding healthy tissue and organs. This treatment may be an appropriate option for certain patients.
