On June 4, a 7-year-old boy who had a rare, malignant brain tumor removed became the first person treated at Stanford Medicine’s new, ultracompact proton therapy facility.
The milestone arrived near the end of patient Stephen De La Torre’s planned radiotherapy treatments; his doctors expect to send him home next week to resume life as a normal, active kid.

We are incredibly proud of our team, whose vision made this possible!
