What are the early symptoms of lung cancer? These early symptoms of lung cancer should be taken seriously

There are a lot of people smoking nowadays. When people smoke, many carcinogens in tobacco will gradually erode their lungs. Generally, many people will develop lung cancer after smoking for more than ten years. When people suffer from lung cancer in the early stages, they will experience coughing, chest tightness and shortness of breath.

In recent years, the incidence and mortality of lung cancer have been increasing. This is inseparable from people's smoking. This does not mean that non-smokers will not get lung cancer, but the chance of getting lung cancer is relatively small. When people suspect that they have lung cancer, they usually do a CT scan. So, what are the early symptoms of lung cancer?

First of all, early lung cancer will show many lumps on the film when it is examined by CT. These are mainly round or irregular masses close to the hilum of the lung, which may have burrs or lobes. In addition, many people's CT films will show emphysema.

Secondly, when people have early lung cancer, they often experience chest tightness and shortness of breath. If people have a better physique, this phenomenon is not very serious. If the patient's physique is not good, this situation is very obvious. The reason for this phenomenon is that the mediastinal lymph nodes are widely metastatic, compressing the trachea, carina or main bronchus, which may cause shortness of breath or even suffocation. Or it may be caused by pleural effusion in lung cancer.

In the early stages of lung cancer, cancerous tissue often invades the lymph nodes. If the lymph nodes are swollen, the patient will experience hoarseness. This generally indicates direct mediastinal invasion or enlarged lymph nodes involving the ipsilateral recurrent laryngeal nerve, resulting in paralysis of the left vocal cord. In more serious cases, chest tightness, shortness of breath, and even suffocation may occur.

The main symptoms of early lung cancer are chest tightness, shortness of breath and hoarseness. This is quite common. The CT scans of patients with early lung cancer also show the same symptoms. If you have coughing, coughing up blood, chest tightness, shortness of breath and hoarseness in your daily life, you should pay attention to it.
