What are the clinical symptoms of lung cancer? Two clinical symptoms of lung cancer

Everyone knows the dangers of lung cancer, but many people think that this disease is unlikely to happen to them, so they don't pay much attention to changes in their physical condition in their daily lives. This is a very serious problem. So what are the clinical symptoms of lung cancer? Here is a brief introduction:

1. Lung cancer is a malignant disease that is easily overlooked. Many patients are diagnosed in the middle or late stages. Early lung cancer generally has no symptoms and is mostly discovered through chest X-rays or CT scans during physical examinations. Once symptoms occur, it is often in the middle or late stages. Therefore, it is important to emphasize regular physical examinations, especially for people with high risk factors for lung cancer (such as smoking, family history, working in a dusty environment, etc.).

2. Usually, lung cancer does not have particularly serious symptoms in the early stages, and the most common symptoms are very common. Common symptoms include cough (non-irritating cough), blood in sputum (blood streaks or blood clots), hemoptysis (small mouthfuls of fresh blood or mixed with blood clots), chest pain (in a more specific location and more persistent), etc. Especially for people with bad smoking habits, they must pay attention to the two symptoms of cough and blood in sputum. If the above symptoms occur, you should see a doctor in time, and don't just take some "cold medicine" or "anti-inflammatory medicine" to get rid of it. On the other hand, the symptoms mentioned above are not specific, that is, if you have these symptoms, it may not be lung cancer, but may also be lung inflammation, tuberculosis, bronchiectasis and other diseases, so if you have these symptoms, the best way is to see a doctor in time.
