This question should be answered specifically. Some people may initially experience symptoms such as weight loss and fatigue when they start to develop lung cancer. Some people with better physical constitution may not lose weight so easily. However, if a malignant tumor persists in the body for a long time, it will consume the body's nutrients and lead to a state of cachexia, characterized by systemic toxicity symptoms including weight loss, fatigue, fever, and other similar symptoms.

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 detect early symptoms of lung cancer?

So, the early symptoms of lung cancer often include a cough, hemoptysis, difficulty breathing, and chest pain. However, these symptoms, particularly the irritating cough, typically appear after the tumor has grown in the larger bronchi; this is often mistaken for a cough following a cold, leading to misdiagnosis or delayed treatment. Therefore, if this type of irritating cough occurs, it is essential to seek medical attention promptly and to undergo chest X-ray or CT scan. Second, as the tumor continues to grow and affects the drainage of the bronchus, secondary lung infections may occur, often characterized by coughing up pus-like sputum, and an increase in the amount of sputum, which should also be noted. Third, a very common symptom is the presence of blood in the sputum, or streaks of blood, or intermittent minor hemoptysis, which must be taken seriously.

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 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.

Staging of Lung Cancer

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.
