With lung cancer, the body will have 5 symptoms, accounting for more than two, and the disease may have reached the middle and late stage

In terms of morbidity and mortality, lung cancer is one of the largest malignant tumors that endanger human health and life. Because lung cancer develops rapidly and has a high degree of malignancy, once clinical symptoms such as chest tightness, bloody sputum, coughing, and chest pain appear, most of them are in the middle and late stages, and the treatment effect is not good. Therefore, early detection and early treatment are particularly important. Although the early symptoms of lung cancer are not obvious, it is easy to be confused with colds, bronchitis, pneumonia and other diseases. However, we still need to understand some subtle symptoms. Once discovered, we must go to the hospital for examination in time.

Although at this stage of canceration, although there are many ways to control the development of the disease, it is necessary to achieve clinical cure, especially in the late stage, the fatality rate is higher!

Therefore, early detection and early treatment of lung cancer are very important. For the high-risk group of lung cancer, you should always pay attention to the changes in your body. If you have the following five symptoms, be careful, this is the signal of lung cancer:

Cough: The most typical symptom of lung cancer is cough. Nearly 75% of patients will have cough symptoms at different stages of the disease, and the degree of coughing is also different. However, nearly 50% of lung cancer patients have paroxysmal irritating cough, and the patient has no sputum or only a small amount of foamy sputum when coughing. In addition, the situation of coughing sputum after secondary infection of lung cancer patients will also change. The tumor grows in the bronchi and stimulates the formation of the bronchial mucosa.

Blood in the sputum : The symptoms of blood in the sputum of patients with early lung cancer have certain particularities, such as central lung cancer, blood in the sputum, etc. Hemoptysis usually occurs in the middle stage, but the amount of bleeding is not much, and the blood is mostly bright red With foam. Because the surface of the cancer is rich in blood vessels, the texture of these blood vessels is very fragile, and it is easy to damage the surface of the blood vessels when coughing, resulting in blood vessel rupture and bleeding;

Feel chest pain: As mentioned earlier, the lungs are located in the chest cavity of the human body. Therefore, when lung cancer changes and pain occurs, chest pain is the main symptom. According to the data survey, it accounts for about 25% of all lung cancer patients' first onset, and the early pain is mainly irregular, paroxysmal dull pain or dull pain. And as the lung cancer continues to develop and invades the pleura, chest wall and other parts, the pain will gradually deepen;

Fever: According to clinical data, patients with fever as the first symptom account for about 20-30% of the total number of cases. There are usually two cases of fever caused by tuberculosis. One is obstructive pneumonia, which is more common in patients with lung cancer. The patient's body temperature is usually around 38°C, and rarely exceeds 39°C. Furthermore, it is cancerous fever, which is mostly related to the body’s absorption of tumor necrosis. Even if anti-inflammatory drugs are used for this type of fever, the symptoms are not easy to alleviate or disappear;

Hoarseness: After the recurrent laryngeal nerve is compressed, hoarseness can be caused, but there are no symptoms of sore throat or other respiratory infections. Squeezing the esophagus can cause difficulty in swallowing, and even a broncho-esophageal fistula can occur, causing lung infection. Those with severe airway compression can die of suffocation. This situation may be caused by lung cancer and lymphatic metastases compressing the recurrent laryngeal nerve, and compression of the recurrent laryngeal nerve will cause paralysis of the left vocal cord, resulting in hoarseness.

The manifestations of lung cancer vary with age, pathological type, and specific location, resulting in different early manifestations.

Everyone's physical condition is different, and the symptoms that may appear are also different. In short, when your body is abnormal, you should go to the hospital for examination in time, and continue to pay attention to it, so as not to make the condition worse.
