What are the early symptoms of lung cancer? 1, dry cough

Cough is a very common disease in our daily life. There are many reasons for cough, such as tracheal diseases, lung diseases, systemic diseases and so on.

Among them, lung cancer can also cause patients to have dry cough in the early stage, often causing dry cough, which is related to malignant tumor squeezing into trachea or tumor cells invading pleura. Dry cough is mainly manifested as paroxysmal dry cough without phlegm or less phlegm.

2, coughing up blood or sputum with blood.

Everyone should pay attention to the situation of blood in sputum or coughing up blood, and go to the hospital immediately, because this situation is most likely caused by lung cancer.

Tumor cells are likely to invade the capillaries around the lungs, leading to the destruction and bleeding of capillaries, which in turn leads to blood in sputum or hemoptysis.

3, chest pain

The first symptom of some lung cancer patients is chest pain, which is mainly manifested by sudden dull or dull pain of unknown reasons in the breast. If there is a cough, it will continue to feel more intense pain. The basic cause of chest pain is that tumor cells invade the chest wall and gradually spread around.

4, difficulty breathing

Once we have difficulty breathing, we should pay attention to the probability of lung cancer. Because the lung is the main respiratory system of our body, if there is something wrong with the lung, it will affect people's breathing.

Lung cancer often leads to dyspnea. This is because the malignant tumor of the lung narrows the indoor space of the lung, which leads to the obstruction of lung ventilation, and then causes patients to have symptoms of dyspnea such as chest tightness, shortness of breath, wheezing and asthma.
