肺是人体重要器官,其起到呼吸氧气排出浊气的作用,当人长期处于砷化合物、二氯甲醚等致癌环境中,或因电离辐射、遗传等因素影响,会使得细胞出现异常增长、分化,形成新生物即为癌症~([1])。肺癌是临床恶性肿瘤中较为常见类型,此病临床早期症状不明显,当患者出现疼痛等症状时,疾病均已发展至中晚期,对于晚期肺癌患者多采用化疗、放疗等方式,控制疾病发展、缓解患者疼痛、延长患者生存时间~([2])。此时早发现、早诊断在疾病治疗中有重要意义,且对于周围型小肺癌
The lung is an important organ of the human body. It plays the role of breathing oxygen to remove muddy gas. When a person is in a long-term carcinogenic environment such as arsenide and dichloromethyl ether, or due to ionizing radiation, genetic or other factors, it will cause abnormal growth of cells. Differentiation, the formation of new creatures is cancer ~ ([1]). Lung cancer is a relatively common type of clinical malignancy. The symptoms of the disease are not obvious in the early clinical stage. When the patient develops pain and other symptoms, the disease has developed to the middle and late stages.

Early detection and early diagnosis are of great significance in the treatment of diseases, and for peripheral small lung cancer
