Leo Cancer Care is using ASTRO 2025 to launch Grace, the company’s upright photon therapy system. Grace is named after American computer scientist and U.S. Navy Rear Admiral Grace Hopper, who famously said, “The most dangerous phrase in language is ‘But we’ve always done it this way.'” The name reflects Leo Cancer Care’s mission to challenge the conventions of radiation therapy.

Grace will deliver conventional X-ray radiation therapy with patients positioned upright, a natural posture that growing global research indicates may support more consistent anatomical positioning and organ stability compared with conventional supine treatments. Patients who have experienced the technology report that the upright approach also creates a more connected and comfortable experience.
