The treatment of asymptomatic invasive lung adenocarcinoma needs to take into account the patient’s pathological type, clinical stage and other factors, and choose the appropriate surgery, chemotherapy, radiotherapy and other treatment means. Lung adenocarcinoma is a type of lung cancer and belongs to non-small cell carcinoma. Invasive lung adenocarcinoma indicates that the cancer has invaded the basement membrane and invaded the surrounding tissues, and metastasis to other parts of the body may also occur. The treatment of asymptomatic invasive lung adenocarcinoma needs to take into account the patient’s specific condition and choose an appropriate treatment plan. If invasive lung adenocarcinoma is in the early stage at the time of diagnosis, patients can undergo surgical treatment, and the survival period can be prolonged with adjuvant chemotherapy and other treatments after surgery. Some middle and late stage lung adenocarcinoma patients are no longer eligible for surgery, and radiotherapy, chemotherapy, targeted therapy and other means are mostly used to prolong the survival time. It is suggested that patients should go to regular hospitals in time and receive standardized treatment under the guidance of doctors and in combination with their own conditions, so as to avoid delays in their condition.
