Objective: To evaluate the current cancer burden and the dominant risk factors of cancer in Eastern Asia, and to provide the preventive strategies for cancer control. Methods: The measures such as incidence, mortality and prevalence of cancer were selected to examine the cancer burden by using global cancer databases and the data of cancer incidence in the five continents, and the future preventive strategies were developed on the basis of the results. Results: The new cancer cases, cancer deaths and the cases living with cancer in Eastern Asia were more than 2.8 million, 2 million and 4.9 million per year, respectively. The five most-frequently-diagnosed cancers were gastric cancer (18.7%), lung cancer (16.9%), liver cancer (14.2%), esophageal cancer (9.4%) and colon/rectal cancer (9.1%), accounting for 68% of the total new cancer cases per year. We predicted that the numbers of the new cancer cases and the cancer deaths in Eastern Asia by the year 2050 were estimated to be 6 million and 4.5 million, respectively. Conclusion: Cancer is a current serious public health problem in Eastern Asia, and will be a continuosly substantial problem in the future. The guidelines of cancer control should be focused on the preventive strategies in Eastei Asia.
