Dear Colleagues and Friends,

It is with great delight that we invite you to join us on the momentous occasion of the 5^th International Congress of the Asian Oncology Society (AOS 2025), held in conjunction with the 51^st Annual Meeting of the Korean Cancer Association, in Seoul, Korea on July 3-4, 2025.

AOS 2025 promises to be an extraordinary gathering under the theme, "Connect and Collaborate to Conquer Cancer." This theme reflects the core of our mission - build meaningful connections, foster multidisciplinary collaborations, and empower each other as we advance cancer research and treatment.

Following the success of AOS 2022 in Seoul, AOS 2025 will once again serve as an unparalleled platform for sharing knowledge, exploring the latest innovations, and collaborating with colleagues from diverse backgrounds to drive impactful change. We are confident that the congress will not only offer valuable insights but also inspire and empower participants to drive meaningful change together.

Be sure to mark your calendar for this must-attend congress and join us at AOS 2025.
We look forward to welcoming you to Seoul, Korea.

Sincerely yours,

Sun Young Rha, MD, PhD
President
AOS 2025 Organizing Committee
