What are the examination methods for lung cancer

The most important examination method is chest CT. Another examination is percutaneous lung puncture biopsy, which can find tumor cells. The examination methods for lung cancer are as follows: First, consider non-invasive examinations. The simplest is chest X-ray. Second, chest CT, followed by MRI, and bone scan. If the diagnosis is unclear, PET-CT can be used. At the same time, after lung cancer is confirmed, other imaging examinations should be completed, such as head MRI, CT, superficial lymph node color Doppler ultrasound, abdominal color Doppler ultrasound, CT, etc., to assess whether the patient has distant metastasis, clarify the patient's clinical stage, and provide a good basis for the next step of treatment.

How long can you live with early symptoms of lung cancer?

If lung cancer is found in the late stage, these patients generally have a late survival, but if they choose the right treatment plan and respond well to it, they can also survive for a long time. Lung cancer in the late stage may not be cured by surgery, and only palliative radiotherapy, chemotherapy and targeted drug therapy can be performed. Lung cancer is generally divided into four stages: stage I, stage II, stage III, and stage IV.

What does it mean when lung cancer invades the pleura?

When lung cancer invades the pleura, it is proven to be in the late stage and there are many symptoms. Different people will have different symptoms, but the main symptoms are pleural effusion or pleural effusion. If blood metastasis and lymph node metastasis occur, there may be distant organ metastasis, which cannot be cured by surgery. Radiotherapy, chemotherapy, targeted therapy, immunotherapy, etc. are performed according to the patient's condition. If diagnosed with advanced lung cancer, it is recommended to see a doctor for radiotherapy and chemotherapy.
