Mayo Clinic launches Proton Beam Therapy Program

The next chapter in cancer treatment

Mayo Clinic introduces its Proton Beam Therapy Program, with treatment for patients available in new facilities in Minnesota beginning in summer 2015 and Arizona in spring 2016.

Proton beam therapy expands Mayo Clinic's cancer care capabilities. In properly selected patients — especially children and young adults and those with cancers located close to critical organs and body structures — proton beam therapy is an advance over traditional radiotherapy.

Mayo Clinic's Proton Beam Therapy Program differs from most other programs in the United States — it exclusively features intensity-modulated proton beam therapy with pencil beam scanning. This, the latest form of proton beam therapy, uses spot scanning to deposit streams of protons back and forth through a tumor, closely targeting the tumor and sparing healthy tissue.

Every patient's tumor is unique. Mayo Clinic doctors and other specialists develop an individualized plan for each patient. Proton beam therapy will be the best option for certain patients and tumor types while others may benefit from a different approach — another type of radiation therapy or no radiation at all. Mayo Clinic patients have a full range of cancer treatment options.
