Oncology is rapidly gaining acceptance as a medical discipline throughout Asia. However, there is a need to increase awareness that the research, epidemiology, clinical spectrum and, of necessity, management strategies for cancer in this region are different from those in Western countries. It was therefore necessary that we, as scientists dedicated to the research and clinical activity of cancer, should join together to establish the Asian Oncology Society (AOS).

AOS has served as a unified organization of APFOCC(the Asian and Pacific Federation of Organizations for Cancer Research and Control) and ACOS(Asian Clinical Oncology Society) since 2018. APFOCC was founded on the purpose of cancer prevention and cancer control policies by Dr. Kunio Ohta and others (Tokyo Univ., Japan) in 1972 and ACOS was for clinical activities by Dr. Tetsuo Taguchi (Japan), the late Jin-Pok Kim (Korea) etc. in 1991. AOS will include every part of oncology as their mission ranging from basic, clinical research to cancer prevention, treatment, and education.
