Don't ignore these abnormalities in your body recently, this may be the manifestation of lung cancer!

At present, the incidence of lung cancer in China is increasing year by year. It is the most common malignant tumor in China, with nearly 800,000 newly diagnosed patients every year .

　　However, because the initial symptoms of lung cancer are not obvious and atypical , more than 2/3 of the patients have already reached the middle and late stage , or even the terminal stage, when they first seek medical treatment .

　　So the question is, if there is a disease in the lungs, is there really no symptoms? wrong!

　　In fact, after the onset of lung cancer, it is not asymptomatic to check, which mainly depends on the patient's specific lung disease area, the pathological type, stage, age and other aspects of the lung cancer.

　　Judging from the current clinical data, in the development stage of lung cancer, the following three symptoms often find patients:

1. Repeated coughing

　　Cough can be said to be a common symptom of all respiratory diseases, and lung cancer is no exception. However, the cough caused by lung cancer is different from other acute and chronic respiratory diseases. The patient initially presents as a paroxysmal, irritating dry cough , which is like a cough that is irritated by a foreign body in the trachea, and the cough medicine is not easy to control.

　　If a patient who smokes for a long time and has chronic respiratory disease, the degree of cough has gradually increased and the frequency has become more and more frequent recently. This requires high vigilance against lung cancer;

2. Blood in sputum

　　This is a common symptom of chronic pharyngitis, but it can also be associated with lung cancer. Clinically, nearly 30% of lung cancer patients in China are accompanied by symptoms such as blood in sputum and hemoptysis when coughing.

　　The reason for this is because the lung cancer continues to grow, and the surface of the cancer is covered with many twisted and irregular blood vessels . The texture of these blood vessels is very fragile . Respiratory secretions are mixed together and excreted by coughing.

　　In addition, if the patient's tumor has local necrosis, or is associated with vascular inflammation, intermittent or continuous repeated small amounts of blood in sputum and hemoptysis will occur ;

3. Chest pain

　　The most typical feature of cancer is its ability to metastasize, invade, and spread. If a patient has peripheral lung cancer, the cancer cells continue to invade areas such as the parietal pleura, chest wall, etc. , which may cause sharp or intermittent pleural pain.

　　As the patient's condition progresses, it will evolve into constant drilling pain. In addition, chest pain may also occur when cancer cells invade the mediastinal nerve, involve blood vessels, and peribronchial nerves .

　　It can be seen from the above content that even if lung cancer has manifestations, it is difficult for people to think of lung diseases. Instead, it is considered in terms of acute and chronic respiratory diseases. Most patients purchase drugs and infusions on their own even without examination. treatment, and ultimately missed the best time for treatment of the disease.

　　Therefore, for people with high risk of lung cancer, such as family history of lung cancer, long-term smoking, chronic lung disease, etc., it is necessary to increase the vigilance of lung cancer, and it is necessary to seek medical attention regularly and seek medical treatment in time when symptoms appear.
