1.On whether lung cancer metastasizes and spreads throughout the body: Nowadays, more and more studies prove that tumor is the local manifestation of systemic diseases, in this sense. Lung cancer is only a local manifestation of tumor, and the spread and metastasis may also be a new tumor, which is the fundamental point of the current tumor treatment that is difficult and incurable. In other words, all current treatments cannot cure it. 2.How long can I live after lung cancer surgery? This is a question that varies from person to person and cannot be answered. From the current research and treatment status, the 5-year survival rate can be increased by about 20% through treatment, and the reports vary from center to center. Without treatment, most patients will die within 1 year. 3.Value of lung cancer treatment: The value of lung cancer treatment mainly lies in relieving symptoms and prolonging life. As for the amount of prolongation, it is not specific to a patient, but only a statistical probability. It is not possible to say clearly for a particular patient. 4. Risks of lung cancer surgery: Patients with lung cancer are older, which is a risky surgery in itself. In addition, the combination of heart, liver, kidney, diabetic or respiratory conditions can increase the risk of postoperative complications. Nowadays, only the improvement of medical treatment has reduced the risk, but not completely eliminated it. In addition, it is the surgery itself that brings pain to the patient, such as: postoperative breathing difficulties, tiredness after activity, wound pain, etc. 5.Surgery method This can only be used according to the specific situation of each patient, the choice of suitable for their own way. There is no best, only according to the doctor, the hospital, a reasonable choice, it is best to communicate with the doctor, jointly agreed. 6.Some people say that surgery will accelerate the spread of tumor and promote death? For some people, this is true. But most people benefit from the surgery. This does not negate the value of surgery. As for who benefits from surgery, there is no accurate determination yet, and it is difficult to make an accurate determination because it can only be made based on evidence-based medical opinion. 7. How to decide whether to operate or not? Personally, I would say: First, the disease itself requires surgery, and the surgery can be relatively complete. Second, the patient is able to tolerate surgery through examination. Thirdly, the patient may benefit from surgery through examination and according to the current treatment status. 8. What about post-operative radiotherapy and chemotherapy? It is not easy to say. Surgery is still only a local treatment for tumors, and the existing examination can only detect relatively large tumors, and it is impossible to detect scattered or small lesions and solve them all through surgery. Now there is no better method, the side effects are big, but it has irreplaceable advantages. 9.How about no treatment? There are indeed such cases in the clinic, and they have lived for years without treatment. Whether to treat or not depends entirely on the patient himself, according to his specific situation, because lung cancer is a tumor with high incidence and mortality rate, in other words, the treatment effect is not good, and the most important thing is one’s own mentality. Maintaining an optimistic state of mind may be the best means of treatment.
