What is Proton Therapy?

Proton Therapy

Proton therapy is an advanced form of radiation therapy that uses a beam of protons, rather than X-rays or electrons, delivered directly to the tumor, destroying cancer cells while minimizing damage to healthy tissues. Clinicians can calculate the precise depth of your tumor while sculpting the doses to confirm the tumor’s complex shape using pencil beam scanning. That results in the ability to precisely target tumors located adjacent to critical structures in the body.

Depending on your particular situation and type of cancer, proton therapy may be combined with chemotherapy, immunotherapy, or surgery. You and your doctor will discuss the options to determine if combination therapy is right for you.

Proton therapy has been used to treat cancer for more than 50 years. It is an established form of treatment for specific indications widely accepted by physicians, government agencies, and many insurers. In addition, 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.
