Introduction
For early-stage lung cancer, if the condition is relatively stable and there are no high-risk factors present after surgery, timely early intervention does not require chemotherapy. Although chemotherapy is generally unnecessary for early-stage lung cancer in most cases, some patients may have an unstable condition or high-risk factors after surgery, such as large tumor size, close relationship with surrounding tissues, or vascular or lymphatic invasion; chemotherapy is recommended in these situations.
Whether chemotherapy is needed in the early stages of lung cancer mainly depends on whether the condition is stable and whether there are high-risk factors after surgery. Detailed explanations are as follows:
Lung cancer is a malignant tumor originating from the bronchial mucosa or glands. When the tumor in early-stage lung cancer has a clear boundary with the surrounding tissues, and there is no metastasis or spread of cancer cells, and the condition is relatively stable without high-risk factors after surgery, timely early interventions such as surgical treatment can usually completely remove the tumor, and chemotherapy may not be necessary.
Although chemotherapy is generally not required in most cases of early-stage lung cancer, some patients may have unstable conditions and high-risk factors after surgery, such as large tumor size, close relationship with surrounding tissues, or invasion of blood vessels or lymphatic vessels. In such cases, specialists may recommend further adjuvant chemotherapy and radiotherapy based on postoperative pathological findings to reduce the risk of recurrence.
In daily life, it is recommended to quit smoking, avoid passive smoking, reduce occupational exposure to carcinogens, maintain indoor air quality, eat a balanced diet rich in vegetables and fruits, exercise moderately, reduce indoor and outdoor air pollution, and undergo regular medical check-ups.
