The claim of the probability of worsening of squamous lung cancer is inaccurate due to the fact that squamous lung cancer itself is a malignant tumor. Lung squamous carcinoma is squamous epithelial cell carcinoma of the lung, which is a malignant cancer itself, and there is no such thing as worsening of squamous carcinoma of the lung. Lung squamous carcinoma mostly originates from the bronchial mucosa, and it usually occurs in older men and people who smoke more. This kind of cancer usually produces slowly, metastasizes later, has a high possibility of surgical resection, and the five-year survival rate is usually higher. Early stage of squamous lung cancer often causes bronchial stenosis, pulmonary atelectasis or obstructive pneumonia, which triggers a series of symptoms such as infections, and can be characterized by coughing, sputum, chest pain and other symptoms. The survival rate of patients with squamous lung cancer treated with early surgery is higher. If patients have symptoms such as unexplained cough, chest pain, hemoptysis, etc., they should consult a doctor as soon as possible to get a clear diagnosis and specific treatment.
