1981年癌症死亡占日本国民死因的第一位,目前4个死亡者中有一人死于癌,因此要求采取有效的综合性措施。本文就癌的现状,以年次比较分析,对今后的抗癌措施等问题试从流行病学角度进行探讨。一、日本的癌动向关于癌的死亡数、死亡率、年龄修正死亡率,按每隔15年(如1955、1970、1985年)并按不同部位、性别进行统计。1.死亡数和死亡率死亡数指一年里因患癌死亡的人数,它作为社会现象是医疗措施上的重要指标。所有部位的癌与30年前相比,男性增加了2.7倍,女性增加2.1倍,显示了因癌死亡人数多少。从不同部位上来看,除子宫无变化,女性胃和食管形成平衡状态外,所有的
Cancer deaths accounted for the first cause of death among Japanese nationals in 1981, and one of the four deaths currently dying of cancer requires effective comprehensive measures. This article examines the status quo of cancer, compares and analyzes every year, and tries to explore the issues of anti-cancer measures in the future from the perspective of epidemiology. First, the trend of cancer in Japan The number of cancer deaths, mortality, and age-adjusted death rates were calculated at different sites and genders every 15 years (eg, 1955, 1970, and 1985). 1. Number of deaths and deaths Deaths refer to the number of deaths due to cancer in a year. As a social phenomenon, it is an important indicator of medical measures. Compared with 30 years ago, men in all sites had a 2.7-fold increase in men and a 2.1-fold increase in women, indicating how many cancer deaths occurred. From different points of view, except for no change in the uterus, the female stomach and esophagus form a balanced state, all
