A large scale cohort Study, 1966-88 in Japan, for 265, 118 adults revealed daily cigarette smoking as the most important risk factor for cancer of all sites and major sites. The risk was observed to go up further when daily alcohol drinking and daily meat consumption are added to daily smoking, while addition of daily consumption of green-yellow vegetables was found to lower down the risk. Smoking cessation and nutrition improvement as represented by daily consumption of green-yellow vegetables, therefore, must be the most practical and promising strategies for cancer prevention.
一项针对日本265,118名成年人开展的大规模队列研究（1966年至1988年）表明，每日吸烟是所有部位及主要部位癌症的最重要风险因素。当每日饮酒和每日肉类消费与每日吸烟并存时，风险进一步上升，而每日食用黄绿色蔬菜则可降低风险。因此，戒烟以及以每日食用黄绿色蔬菜为代表的营养改善，必定是最切实可行且前景广阔的癌症预防策略。
