How long a patient with squamous lung cancer can live depends on the actual condition of the patient and is related to the clinical stage, molecular characteristics, treatment response and the patient’s physical condition. Squamous lung cancer is also known as squamous cell carcinoma of the lung, of which central lung cancer is the most typical type of squamous lung cancer. Squamous lung cancer grows more slowly and metastasis occurs relatively late. Patients with early-stage squamous lung cancer prefer surgery, which has a relatively high five-year survival rate, and some patients can be cured. In the case of mid-stage squamous cell lung cancer, patients can also achieve better treatment effect through surgery combined with chemotherapy, which can prolong the survival period appropriately. If it is advanced lung squamous cell carcinoma, the treatment is more difficult and the treatment effect is poorer, and radiotherapy and chemotherapy are usually available. Without treatment, the survival period of advanced squamous lung cancer usually does not exceed 1 year. During treatment, patients need to pay attention to maintain an optimistic state of mind and it is recommended to have a light diet and avoid spicy and stimulating foods.
