Welcome Letter

3-6 JUNE 2026 CANCUN, MEXICO

Dear colleagues,

It is with great pleasure that I invite you to the Paediatric Radiation Oncology Society (PROS) Congress 2026, taking place in Cancun, Mexico, from June 3 to 6, 2026.

This biennial meeting is the premier international forum for all professionals dedicated to using radiation to treat childhood cancers. Whether you are a radiation or clinical oncologist, therapeutic radiographer or radiation therapist, medical physicist or clinical scientist, or part of the wider multidisciplinary team, this Congress offers a unique opportunity to come together, share knowledge, and advance care for children and young people with cancer.

PROS is proud to represent a truly global and multi-professional community focused on improving outcomes through all forms of radiation therapy – including photons, protons, brachytherapy, and molecular radiotherapy. The 2026 Congress will continue this mission by fostering exchange on clinical research, technical advances, multi-modality approaches, and survivorship care.

The programme will feature updates from international clinical trials, proffered papers, invited presentations, and poster sessions, all within a friendly and collegial atmosphere. And of course, you’ll have time to connect with colleagues from around the world and enjoy the beautiful setting of Cancun.

We look forward to welcoming you to Mexico for what promises to be an inspiring and engaging PROS Congress.

With warmest regards,
Mark Gaze
President, PROS
