Lung adenocarcinoma can be categorized into 5 types pathologically: adnexal, alveolar, papillary, micropapillary and solid. Alveolar adenocarcinoma is one of the pathological subtypes of lung adenocarcinoma, which often has no specific symptoms in early stage, and can be accompanied by respiratory symptoms such as cough, sputum and blood, low-grade fever, chest pain and tightness of breath. Lung adenocarcinoma of alveolar type often has no obvious discomfort in early stage, and may be accompanied by general respiratory symptoms such as cough, sputum blood, low fever, chest pain, stuffiness and other respiratory symptoms. However, with the development of the disease, other symptoms such as hoarseness, neck and face edema may appear. If the patient is diagnosed with alveolar adenocarcinoma, please go to the hospital for consultation and treatment in time.
