Early detection of small cell lung cancer may be curable, but it still needs to be determined in combination with treatment and physical condition. Small cell lung cancer is a type of lung cancer with higher malignancy and lower overall cure rate. However, in early stage when the lesions are still confined and no metastasis of lymph nodes and distal organs occurs, some patients may still be cured if they can undergo radical surgical resection in a timely manner, and adopt radiotherapy and chemotherapy according to the situation after the surgery. Small cell lung cancer must be detected and treated early, otherwise the disease will develop rapidly in a short period of time, which will increase the difficulty of treatment and develop into the advanced stage, thus posing a threat to the patient’s life.
