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.

What are the symptoms of lung cancer?

The most common symptoms of lung cancer include coughing, particularly irritating coughs, and symptoms of coughing up blood. The blood in the sputum may appear as spots, streaks, or intermittent small amounts. Other symptoms include difficulty breathing and chest pain, as well as potential tightness in the chest, shortness of breath, and fever. Secondly, if lung cancer grows within the thoracic cavity and spreads, invading nearby tissues and organs, it can produce secondary symptoms. For example, paralysis of the phrenic nerve on the same side may lead to difficulty breathing and belching. Compression of the recurrent laryngeal nerve may cause hoarseness; compression of the superior vena cava can lead to distended veins in the face, neck, and upper limbs; subcutaneous edema; and if the pleura is invaded, it can cause pleural effusion, among other symptoms. If lung cancer metastasizes through the bloodstream, it may spread to the brain and potentially lead to symptoms such as headaches, nausea, and vomiting. Metastasis to different regions of the brain might cause various symptoms, including seizures, mental confusion, and vision impairment. In a minority of cases, lung cancer may produce endocrine substances, possibly leading to symptoms like severe muscle weakness, bone and joint pain, and other such symptoms.

Is coughing up blood lung cancer?

Patients with lung cancer can experience hemoptysis, but the occurrence of hemoptysis does not necessarily mean that it is caused by lung cancer. Although hemoptysis is a symptom of lung cancer, there are many other diseases that can cause it as well, such as tuberculosis, bronchiectasis, lung abscess, various pneumonias, certain heart diseases, blood disorders, etc. Therefore, it can only be said that hemoptysis may be an indication of lung cancer, not that hemoptysis confirms the presence of lung cancer.

How long can one live with lung cancer?

The survival period of malignant tumors is a topic of great concern to everyone. The question of how long one can live with lung cancer is very difficult to answer. It should be based on the patient's physical condition and the pathological staging. However, these judgments are only based on a predictive basis and do not determine how long the patient can live. If the patient does not relapse after surgery, is sensitive to radiotherapy and chemotherapy, and shows no signs of recurrence or resistance, then their five-year survival rate is naturally higher. If the patient experiences recurrence and metastasis after surgery, then the five-year survival rate is naturally lower. Therefore, the question of how long a person can live with a malignant tumor cannot be answered generically.

What tests are conducted for lung cancer?

Diagnosis of Lung Cancer: The first method can be through chest X-ray and CT scan; The second is sputum cytology examination; The third involves using a bronchoscopy; The fourth is mediastinoscopy, which allows direct observation of the enlargement of lymph nodes on both sides of the mediastinum; The fifth is to perform PET-CT, which is Positron Emission Tomography-Computed Tomography; The sixth requires a biopsy; it can be done through a transthoracic needle biopsy, or via a bronchoscopic biopsy; The seventh is the biopsy of metastatic lesions, such as subclavian lymph nodes, and lymph node metastases in the neck or axillary areas can be examined; The eighth can involve drawing cancerous pleural effusion; if there is pleural effusion, pleural fluid cytology examination can be performed; The ninth method is thoracotomy exploration; if lung nodules or lung tumors cannot be definitively diagnosed through various other methods, thoracotomy exploration can be performed.

Do early-stage lung cancer patients experience vomiting?

If a patient develops lung cancer, some may experience symptoms of nausea and vomiting in the early stages, which is caused by the spread of cancer cells. Others may experience localized pain. It is suggested that lung cancer patients who experience nausea and vomiting adopt a fasting method for treatment, or treat it through localized massage. If patients discover that they have lung cancer, it is crucial to control it in the early stages to prevent the spread of cancer cells. If necessary, treatment can be administered through chemotherapy drugs or radiation therapy drugs.
