Lung adenocarcinoma belongs to non-small cell carcinoma, which is generally caused by epithelial cell lesions of bronchial mucosa. Its clinical manifestations include cough, sputum, hemoptysis, chest pain and chest tightness, pestle-shaped finger and so on.
1. Cough, sputum, hemoptysis: the lesions are located in the lungs, and the clinical manifestations are mostly cough and sputum. However, as the tumor cells invade the mucosa of bronchial tubes, hemoptysis will occur in some patients, and the degree of hemoptysis varies due to the different physique of patients. If the tumor cells infiltrate into blood vessels, it will cause hemoptysis, which can endanger the patient’s life.
2. Chest pain and chest tightness: with the continuous development of the disease, the tumor cells gradually erode the pleura and involve the ribs and chest wall tissues, thus causing chest pain.
3. Pestle-like finger: as lung cancer cells invade lung tissues, it will cause respiratory difficulty and lack of oxygen, and at the same time, it produces some special endocrine hormones (xenogenic hormones), antigens and enzymes, which will result in swelling and pain in bone and joints, and often involves distal joints, and the ends of fingers and toes are often enlarged in the form of pestle-like finger.
To summarize, clinical manifestations of stage II lung adenocarcinoma are cough with sputum and blood, chest pain and chest tightness, pestle-shaped finger, etc. Patients with lung adenocarcinoma should go to regular hospitals as soon as possible. Lung cancer patients should go to regular tumor hospitals for treatment as early as possible to improve the survival rate.
