5th International Congress of the Asian Oncology Society (AOS 2025)

It is with great delight that we invite you to join us for the momentous occasion of the 5th International Congress of the Asian Oncology Society (AOS 2025) to be held at COEX, Seoul, Korea on July 3-4, 2025.

Since its successful launch as a unified organization of the APFOCC and ACOS in 2019, the AOS has become the most authoritative and representative organization of oncology societies in Asia. Building on this foundation, AOS 2025 promises to be an extraordinary gathering under the theme, “Connect and Collaborate to Conquer Cancer.” This theme encapsulates our ongoing mission: to build meaningful connections, foster multidisciplinary collaborations, and empower one another as we advance cancer research and treatment.

Building on our growing success, we truly believe AOS 2025 will serve as an exceptional platform for all participants—from world-renowned speakers to young investigators and clinical and basic researchers in the field of oncology—to collaborate and forge meaningful relationships for the future.

We aim to bring together all AOS member societies at AOS 2025 and warmly encourage your society members to participate.
