1.What are the common symptoms of lung cancer? The main symptoms of lung cancer include paroxysmal irritating dry cough, no sputum or a small amount of white foamy sputum, hemoptysis, chest pain, chest tightness, shortness of breath and difficulty in breathing. There may also be fever, weight loss and other manifestations (e.g. lung cancer may cause associated tumor syndrome, such as neuromyopathy (myopathy syndrome, etc.), acanthosis nigricans, hypertrophic osteoarthropathy, endocrine changes (Cushing’s syndrome, carcinoid syndrome, etc.). 2. How to diagnose lung cancer? Direct pathological or cytological evidence can be further obtained through imaging examinations including chest X-ray, CT or pet-ct, combined with bronchoscopy, sputum examination for cancer cells, and CT localization aspiration examination. To further determine the extent of the disease, bone scan, brain MRI, abdominal ultrasound, pet-ct and other examinations are also performed. 3.How to treat lung cancer? Surgery is currently the most effective treatment for lung cancer. For lung cancer with no distant metastasis and completely resectable lesions, surgery-based comprehensive treatment is preferred as long as the patient’s physical condition permits. However, unfortunately, most patients are already in advanced stage when they are diagnosed and lose the opportunity of surgery. 4.What are the surgical methods for lung cancer? Generally speaking, lung cancer surgery can be divided into minimally invasive surgery and open surgery. There should be no difference between the two surgical methods in terms of efficacy for experienced surgeons, but minimally invasive surgery allows patients to recover faster and with less pain. Minimally invasive surgery for lung cancer has developed from small incisions to four-hole thoracoscopy, three-hole thoracoscopy, and the current single-hole and single-operated-hole thoracoscopy stage. The damage to patients has been greatly reduced. 5.Do I need other treatment after lung cancer surgery? Generally, the need for post-surgical treatment is further considered based on what is seen in lung cancer surgery and post-operative pathology report. If the disease is advanced, chemotherapy may be added, and in less cases, radiotherapy. 6.How to further follow up after lung cancer surgery? Regular follow-up is required after lung cancer surgery. In the first three years after surgery, our hospital generally takes follow-up every four months. In the first three years after surgery, we usually follow up every four months, and every six months for four to five years after surgery. If there is any discomfort during the period, you should consult the original surgeon as soon as possible. For regular follow-up, the doctor will selectively perform chest CT, abdominal ultrasound or CT, tracheoscopy, bone scan, brain MRI or pet-ct according to specific conditions. 7.What will be the impact on life after lung cancer surgery? Lung cancer surgery will have certain impact on patients’ life. First of all, the lung function of patients will be affected to some extent, the lung is removed on the basis of the original one, and some patients will have difficulty in physical activities or daily life is breathing. Three parts of treatment and seven parts of care, if gradually strengthen respiratory function exercise, lung function will be further improved and the remaining lung can be compensated. Secondly, some patients will feel pain in the incision for several months after surgery, especially in open surgery patients. Minimally invasive surgery is less severe. This is mainly due to the disruption of the intercostal nerves during surgery. In addition, lung cancer surgery will have a great impact on patients psychologically, so doctors and family members should pay attention not to put too much pressure on patients and communicate with them more. 8. How to prevent and detect lung cancer at an early stage? The occurrence of lung cancer is the result of a combination of many factors. It is clear that smoking is closely related to the occurrence of lung cancer, and quitting smoking can significantly reduce the chance of occurrence of lung cancer. For people who are older, are smoking or have a history of smoking, low-dose spiral CT examination can detect lung cancer at an early stage.
