Under the theme of “Integration for Modernity”, on AOS2024 and 2024CCHIO, we will explore the latest advancements in oncology and exchange knowledge that will shape the future of cancer care. We assure you that we have spared no effort in creating an exceptional conference experience. We looking forward to engaging discussions, insightful presentations, and fruitful collaborations among esteemed oncologists, researchers, and healthcare professionals from home and abroad. We convince that this congress would be a catalyst for innovation, unity, and progress in the field of oncology.
Xi'an, with its rich history and vibrant culture, is the ideal setting for this event. As one of the oldest cities in China, Xi'an served as the capital for over 1,000 years and spanned 13 different dynasties. Foreign friends often say, "One has not been to China until he/she has been to Xi'an." We are delighted to invite you to experience the enchanting blend of tradition and innovation that Xi'an has to offer. Immerse yourself in the city's unique atmosphere, explore its bustling markets, savor its renowned cuisine, and discover the hospitality of its people.
We believe that the program will be fascinating for all AOS and CACA members. We encourage you to participate in the conference in person, and look forward to seeing you in Xi‘an, where tradition meets modernity.
