Is pulmonary nodule really a precursor of lung cancer? What symptoms do pulmonary nodules need to be alert for when they are malignant?

1. Is lung nodule really a harbinger of liver cancer? Clinically, 95% of pulmonary nodules are unlikely to worsen, most of them are benign nodules, and some pulmonary nodules can worsen under the stimulation of bad causes. If nodules are found in the lungs, it is best to observe the pulmonary nodules according to breast ct, and to distinguish the characteristics of small nodules according to tumor markers and patients' actual symptoms.

Second, what are the symptoms that need to be vigilant? Lung nodules are malignant 1. Irritating cough.

Malignant pulmonary nodules will grow, develop and multiply rapidly in human body. When its volume increases, it will cause obvious compression symptoms to the surrounding organs and reduce lung function. Patients will continue to have irritating cough after being stimulated by cancer cells. The actual situation of dry cough also needs to be expressed mainly according to the growth position, growth speed and condition of cancer cells. For example, when cancer cells appear in the airway, patients will suddenly cough, have no sputum or have less sputum, and after suffering from the flu, sputum will increase.

2. Cough with phlegm or hemoptysis

Patients with central lung cancer often cough with phlegm, somatic cells in the lungs are often stimulated, and capillaries are likely to rupture and bleed. When a patient has a dry cough, he will find blood in the sputum. If we don't attach great importance to it, there will be obvious symptoms such as purulent sputum and hemoptysis in the future.

3. Chest pain, chest tightness and shortness of breath

Because the lung is located in the human chest area, when cancer cells occur in the lung area, they will stimulate the pleura or chest wall, thus causing dull pain and dull pain in the chest area. With the aggravation of the disease, the pain is severe and lasts longer and longer. Cancer cells invade the airway, causing some hydrops and bronchial stenosis, which will continue to cause chest tightness and shortness of breath.

4. Hot, thin and sleepy

Most patients with lung cancer will have a burning sensation, which is due to cancer cells squeezing lung organs, leading to COVID-19 and lung consolidation. At the same time, the shrinking of the tumor will lead to stimulation to the human body and increase the body temperature. Moreover, cancer cells will digest and absorb the nutrients of the human body, making people thinner and thinner in a short time. If they don't make up their physical fitness immediately, they will easily feel weak.
