I often encounter some lung cancer patients in the course of clinical diagnosis and treatment who, for one reason or another, delayed the formal treatment, so that the early stage lung cancer that could be cured has become incurable, and the lung cancer patients who could be controlled for a long time are dying and helpless. As a patient who does not know about lung cancer, what should he do? Where should they go for treatment? First of all, it is emphasized that the treatment of lung cancer must be multidisciplinary, including thoracic surgery, radiotherapy and chemotherapy, and Chinese medicine has the role of adjuvant treatment. If it is non-small cell carcinoma, relatively limited and has not spread, you should first go to a thoracic surgeon. If you can operate, you should operate first, and after surgery, you should decide whether to adjuvant radiotherapy or chemotherapy according to the situation, and radiotherapy and chemotherapy must go to radiotherapy department. If surgery is not possible, radiotherapy and chemotherapy should be used by doctors in the radiotherapy department. We often encounter some lung cancer patients who go to chemotherapy when they cannot have surgery and have more than ten courses of chemotherapy in the non-oncology ward. Due to the toxic effect of chemotherapy, the patient can’t even walk and is still playing chemotherapy, and metastasis is found while playing chemotherapy. In addition, because many doctors’ knowledge is not updated timely, there is a misconception that small cell lung cancer can only be treated with chemotherapy, in fact, radiotherapy for small cell lung cancer occupies a very important position. The main chemotherapy and local radiotherapy.
