This digest was compiled by AI from multiple sources — links to the originals are below.
Researchers presented findings at the ESTRO 2026 congress showing that a digital AI avatar of a doctor helps cancer patients better understand their treatment and feel less anxious before their first consultation. The avatar, which looked and spoke like a real physician, was developed by Dr. Adam Raben, head of radiation oncology at Helen F. Graham Cancer Center & Research Institute.
The Study
The study was presented at the European Congress of Radiation Oncology (ESTRO 2026) in Europe. Dr. Adam Raben, lead author and director of radiation oncology at Helen F. Graham Cancer Center & Research Institute, reported that the AI avatar reduced patient anxiety before initial consultations. The avatar mimicked the appearance and speech patterns of a real physician, providing pre-consultation information.
Patient Impact
Cancer patients who interacted with the AI avatar showed improved understanding of their treatment plans and reported lower anxiety levels compared to those who did not use the tool. The findings suggest that AI-driven avatars could serve as a scalable intervention to improve patient preparedness. The study did not disclose the exact number of participants or the magnitude of anxiety reduction.
