ABSTRACT
PURPOSE: We estimated the incidence of cancer in Korea. MATERIALS AND METHODS: The indicence of cancer was estimated using national mortality data, and the incidence data from four frontier regional cancer registries, including Kangwha, Seoul, Busan and Deagu. These four registries served a population about seventeen million, which is almost 38% of entire population in Korea. RESULTS: The overall age-standardized incidence rates (ASR) were 287.0 and 163.1 per 100,000 for males and females, respectively. Among males, stomach cancer was the most frequent (ASR 69.6), followed by lung cancers, including bronchus cancer (ASR 54.5), liver cancer (ASR 47.0) and colo-rectal cancer (ASR 25.2). The most frequent sites of cancer in females, by rank order, were stomach (ASR 26.8), breast (ASR 20.1), uterine cervix (ASR 18.0), colo-rectum (ASR 15.9), lung (ASR 13.0) and liver (ASR 12.0). CONCLUSION: It is hoped that these results will provide valuable leads for cancer research and cancer control in Korea.
