Lung microinvasive adenocarcinoma generally cannot be cured by itself, and timely treatment is recommended. Microinvasive adenocarcinoma of lung usually belongs to early stage lung cancer, in which the invasion depth of cancer cells has exceeded the basement membrane, and there is the possibility of invasion of blood vessels and lymphatic vessels, as well as distant metastasis, but it has not reached the degree of complete invasion. It is a type between lung carcinoma in situ and lung invasive adenocarcinoma. Although it is less serious, it has the risk of metastasis and cannot be cured by itself, but its cure rate is higher. For micro-invasive carcinoma with practiced components or close to the pleura, it is usually resected at an early stage by radical surgery such as segmental resection and wedge resection, which can achieve the purpose of cure, and the recurrence rate of 5 years is very low, and it does not even affect the life expectancy. However, if no measures are taken, its cancer cells will gradually spread, making the condition worse and treatment difficult, thus affecting the prognosis. Therefore, it is suggested that patients must be detected early, diagnosed early and treated early.
