A powerful reminder of why innovation in proton therapy matters.

We’re honored that the world’s first patient treated in Stanford Medicine’s new compact proton therapy suite was a 7-year-old boy facing a rare brain tumor. For pediatric patients, proton therapy’s precision can help reduce radiation exposure to healthy, developing tissue—potentially lowering the risk of long-term side effects while delivering effective treatment.

This milestone represents more than a technological achievement. It reflects a shared commitment to making advanced cancer care more accessible for patients and families who need it most.

Through our collaboration with Stanford Medicine, Leo Cancer Care, and RaySearch Laboratories, we’re helping bring proton therapy closer to home for more communities.

A tech breakthrough fits a specialized type of radiation treatment into standard treatment rooms, including at Stanford Medicine.

This week, the Mevion team gathered at our headquarters in Littleton, MA to recognize an important milestone: the first patient treatment using the MEVION S250-FIT Proton Therapy System™.

While this achievement reflects years of innovation, collaboration, and dedication, our focus remains where it belongs: on the patients and families we serve.

As part of the event, employees wrote messages of encouragement for the young patient receiving treatment. The cards were sent to Stanford Medicine Cancer Center to be shared with the patient at the conclusion of their treatment journey.

We're honored to play a role in expanding access to advanced proton therapy and grateful to the clinicians, caregivers, and families who place their trust in this technology every day.

🎉 A major milestone for proton therapy.

Mevion is proud to announce the first clinical treatment delivered on the MEVION S250-FIT Proton Therapy System™ at Stanford Medicine Cancer Center.

This marks the world’s first patient treatment using an ultra-compact proton therapy system installed within an existing conventional radiation therapy vault—demonstrating a new approach to expanding access to advanced proton therapy without the infrastructure requirements of traditional proton centers.

This achievement was made possible through collaboration with Stanford Medicine, Leo Cancer Care, RaySearch Laboratories, Stantec, and NELCO.
