Adenocarcinoma refers to a special type of lung cancer in which the cancer cells grow along the alveolar wall. Clinical symptoms such as cough, chest pain and sputum with blood are common, and the main treatments include surgery, chemotherapy, radiotherapy, and targeted drugs, etc. Although adenocarcinoma grows along the alveolar wall, it usually does not cause damage to the alveolar wall and does not easily infiltrate the surrounding tissues. Although adherent lung adenocarcinoma grows along the alveolar wall, it usually does not damage the alveolar wall and is not prone to infiltrate the surrounding tissues, and hyperplasia is often found in the epithelium of the alveoli in pathological examination. Patients with this type of lung adenocarcinoma in early or middle stage are usually preferred to be treated by surgery, and some patients need to be given adjuvant chemotherapy or adjuvant radiotherapy after surgery. Adherent lung adenocarcinoma is usually treated with chemotherapy, targeted therapy, radiotherapy and other non-surgical treatments when it develops to the advanced stage, which should be chosen according to the doctor’s prescription.
