As the number of cancer deaths has increased, the number of cancer researchers including cancer epidemiologists has increased. Compared to the approaching methods of epidemiologic studies on cardiovascular diseases, those of cancer epidemiology are different. In cancer epidemiology a case-control study has been used most frequently, while in cardiovascular disease epidemiology a cross-sectional study with health examinations in a defined population has been used most frequently. In the latter study a cross-sectional study has been repeated periodically forming a cohort study in a model area. Only few large scale cohort studies on cancer had been conducted previously, but in recent years several large scale cohort studies on cancer have been conducted by several research groups. In recent years there is a trend that epidemiologists in cancer, cardiovascular diseases and other related areas collaborate in conducting a large scale cohort study. Chemoprevention studies on cancer have been initiated by cancer epidemiologists in recent years.
随着癌症死亡人数的增加，包括癌症流行病学家在内的癌症研究人员数量也在增加。与心血管疾病流行病学研究采用的方法相比，癌症流行病学的方法有所不同。在癌症流行病学中，病例对照研究使用最为频繁，而在心血管疾病流行病学中，在特定人群中进行健康检查的横断面研究使用最为频繁。在后一种研究中，横断面研究定期重复进行，在一个示范地区形成了队列研究。此前仅有少数关于癌症的大规模队列研究，但近年来，几个研究小组开展了几项关于癌症的大规模队列研究。近年来，癌症、心血管疾病及其他相关领域的流行病学家合作开展大规模队列研究呈一种趋势。近年来，癌症流行病学家已经启动了癌症化学预防研究。
