肺癌是各国近数十年来发病率急剧增加的癌症之一,工业发达的国家尤为突出。上海市1980年流行病学调查男子肺癌病死率达52.9/10万,占恶性肿瘤第一位。女子24.1/10万,在全世界仅次于香港地区。本文以自然辩证法原则为指导,以临床实践为基础,回顾分析和讨论提高肺癌诊治水平的各种方法。一、Ⅱ级预防的现实意义由于发生肺癌的病因非常复杂,不同的病因因子可诱发或协同加速其发生发展,而不同机体对致癌因子的敏感性也有很大差异,因而影响病因和疾病之间的因果关系,给预防工作带来不少困难。吸烟(特别是女性吸烟)、职业性因子(无机砷、石棉、铬、镍、煤焦和煤的其他燃烧产
Lung cancer is one of the most rapidly increasing incidence of cancer in various countries in recent decades, especially in industrially developed countries.

The number of women is 24.1/100,000, which is second only to Hong Kong in the world. Based on the principles of natural dialectics and based on clinical practice, this article reviews and discusses various methods for improving the diagnosis and treatment of lung cancer. First, the practical significance of class II prevention Because the cause of lung cancer is very complex, different etiological factors can induce or synergistically accelerate its occurrence and development, and different organisms have great differences in sensitivity to carcinogenic factors, thus affecting the etiology and disease The causal relationship has brought a lot of difficulties to prevention work. Smoking (especially female smoking), occupational factors (inorganic arsenic, asbestos, chromium, nickel, coal char, and other combustion products of coal
