The staging of lung cancer is of great clinical significance for the selection of clinical treatment plans and the prediction of prognosis. According to the International Association for the Study of Lung Cancer and the World Health Organization, lung cancer is staged based on the size of the primary tumor (T stage), the condition of tumor lymph node metastasis (N stage), and the presence of distant metastases (M stage). Lung cancer is classified according to these criteria, which are used internationally. Currently, there are UICC staging and AJCC staging, which are two different systems.

Is coughing up blood lung cancer?

Everyone knows that lung cancer can cause coughing up blood, but does coughing up blood necessarily mean one has lung cancer? It should not be interpreted this way. Although lung cancer can cause coughing up blood, there are many reasons for coughing up blood, and it is not only caused by lung cancer. Reasons for coughing up blood can also include bronchitis, pneumonia, bronchiectasis, tuberculosis, lung abscess, and many others. Therefore, if coughing up blood occurs, it doesn't necessarily mean one has lung cancer, and there is no need for excessive worry. If coughing up blood occurs, it is important to visit a hospital in a timely manner, where a doctor can conduct checks like chest X-rays to further investigate the cause.

How to treat dry cough caused by lung cancer?

Dry cough is a very common symptom in clinical practice, caused by many factors which are also very complex. Some patients might clearly have lung cancer. Due to the presence of lung cancer lesions, patients can experience irritating dry cough as well as symptoms like hemoptysis, chest pain, and chest tightness. It is possible that some patients do not exhibit symptoms of dry cough, perhaps due to other causes. Therefore, for dry cough, we need to identify if it is caused by lung cancer, as it often requires surgical treatment to control the symptoms. Some patients with minor lung cancer who experience dry cough might be able to control it with appropriate medications. However, to effectively control symptoms of dry cough caused by lung cancer, surgical removal is generally necessary and is the ultimate treatment plan.

Does lung cancer cause coughing?

The most common symptoms of lung cancer patients include coughing, followed by coughing up blood, difficulty breathing, and chest pain. When the tumor grows in larger bronchi, it often causes an irritable cough, which can easily be mistaken for a cold. As the tumor continues to grow and affects the drainage of the bronchi, secondary lung infections can occur, possibly producing purulent sputum and an increased amount of coughed-up sputum. At this time, coughing becomes quite severe. Another symptom that may appear is blood in the sputum, which could be blood-streaked sputum, or sporadic, small amounts of coughed-up blood.

How to check for lung cancer?

How to check for lung cancer, firstly, for lung cancer screening, particularly in people over forty years old, especially smokers, it is recommended to regularly undergo low-dose spiral CT scans of the chest. Secondly, if a tumor is detected, it is suggested to proceed with enhanced CT scans, sputum cytology tests, or PET-CT. If it is confirmed that there is a tumor in the lungs, then a biopsy is needed. The biopsy can be performed under bronchoscopy, or transthoracic lung puncture and biopsy of living tissue can also be done, as well as biopsy of metastatic lesions or cytological examination of pleural effusion to diagnose whether it is lung cancer, the type of lung cancer, and certain immunohistochemical situations.
