What are the mid-term symptoms of lung cancer? 4 symptoms of lung cancer

Lung cancer is a common malignant tumor disease. The initial symptoms are not very obvious and are easily overlooked. Usually, most patients are already in the middle and late stages when diagnosed. If effective treatment is not carried out in time, the difficulty of treatment will be greatly increased and even life-threatening. The following is a detailed introduction to the mid-term symptoms of lung cancer. 1) Hemoptysis: The hemoptysis of patients in the middle stage of lung cancer worsens, and the duration varies. The mid-term symptoms of lung cancer are intermittent and repeated small amounts of bloody sputum, and occasionally large coughing up blood, the blood is mostly bright red. The duration of hemoptysis varies, generally only a few days, but there are also cases of several months. 2) Symptoms of lung cancer Hoarseness: The tumor invades the left side of the mediastinum, compressing the recurrent laryngeal nerve and causing hoarseness. Fever 21.2% of lung cancer has fever as the first symptom. Fever is caused by inflammatory fever caused by compression and obstruction of lung cancer, or cancer fever caused by degeneration and necrosis of cancerous tissue 3) Cough and shortness of breath: In the middle stage of lung cancer, when the tumor enlarges and causes bronchial stenosis, the cough worsens and the breath is short, mostly persistent, with a high-pitched metallic sound. If there is secondary infection at the distal end of bronchial stenosis, the amount of sputum increases and becomes mucopurulent. 4) Symptoms of lung cancer Chest pain: caused by tumor involvement of the pleura, dull or dull chest pain may occur; if the tumor invades the chest wall ribs or compresses the intercostal nerves, there will be sharp chest pain, fixed or local tenderness, which will be aggravated with breathing, coughing, and changing body positions. It is due to tumor compression, obstruction, tracheobronchial stenosis, and bronchial obstruction that causes shortness of breath. The above are all mid-term symptoms of lung cancer.
