吸烟是引起男性肺癌的主要原因,这已被世界上多数流行病学及其它方面的研究所确认.近年来在欧美,男性吸烟量大幅度降低,但由于癌发病的潜伏期较长,吸烟量减少是否就反映了肺癌发病率的降低,引起了公共卫生学术上的兴趣。近年日本男性肺癌发病率显著增加,预计5年内超过胃癌,占癌死亡率的首位.目前对癌症尚无有效疗法,故预防措施极其重要.本文根据美国统计的吸烟率降低与肺癌患病率.死亡率的变化来研讨戒烟的重要性。据美国1987年国家卫生部门调查表明,部分家庭男性吸烟率为31.2%,与1965年的51%、1974年的43%相比明显降低,特别是18～24岁的青年组在所有年龄组中为最低(28.1%)。另外,由于摩门教徒中不吸烟者居多,Utah 州的肺癌发病率也明显偏低。另一方面,从死亡率的研讨来看,仍是青年组肺癌的
Smoking is the main cause of lung cancer in men, which has been confirmed by the majority of epidemiological and other studies in the world.In recent years, men and women in the United States and Europe have significantly reduced the amount of smoking, but because of the longer incubation period of cancers, smoking is reduced Does it reflect the reduced incidence of lung cancer, causing public health academic interest. In recent years, the incidence of lung cancer in Japanese men increased significantly, and it is estimated to exceed gastric cancer in 5 years, accounting for the first place in cancer death rate.Now there is no effective therapy for cancer, so precautionary measures are extremely important.This article based on the United States reduced smoking prevalence and lung cancer prevalence. Mortality changes to study the importance of quitting smoking. According to a survey conducted by the U.S. National Department of Health in 1987, the percentage of male smokers in some households was 31.2%, significantly lower than 51% in 1965 and 43% in 1974. Especially among young people aged 18-24, in all age groups The lowest (28.1%). In addition, due to the large number of non-smokers among Mormons, the incidence of lung cancer in Utah State is also significantly lower. On the other hand, from the study of mortality, it is still young group lung cancer
