WELCOME TO AACR 2026

With more than 22,100 registrants from 85 countries and territories, the American Association for Cancer Research® (AACR) Annual Meeting 2025 held an Opening Ceremony April 27 that was highlighted by a powerful "Call to Action." Thousands of attendees held up signs reading "Cancer Research Saves Lives" in support of robust and sustained funding for the National Institutes of Health (NIH).

"As the world's first and largest cancer organization, AACR is globally recognized as the driving force behind scientific advances and practice-changing treatments for cancer," said Margaret Foti, PhD, MD (hc), CEO of the AACR. "However, while we recognize the incredible strides that are being made in the fight against cancer, we must acknowledge that our work is not finished."
