What are the symptoms of lung cancer? There are 5 symptoms when lung cancer occurs

Everyone knows that the main cause of lung cancer is smoking, which is more common in men and causes great damage to the lungs. However, many people do not understand the specific symptoms of lung cancer. Many patients think that they have common colds when they are sick, which leads to lung cancer not receiving timely treatment and worsening the condition. The following will introduce the symptoms of lung cancer in detail.

1. Hemoptysis occurs intermittently, the amount can be more or less, the color can be bright red, or dark, or blood in the sputum is not mixed, and comes out with rotten flesh; damage to the large collaterals or the formation of cavities in the cancer nest can cause bleeding, or block the airway and suffocate, or the loss of qi and blood can all lead to sudden death. Hemoptysis caused by deficiency syndrome often cannot stop by itself, and the sputum and blood are mixed, and it does not stop for a long time. However, most of them are first real and then virtual, and the virtual and real are mixed. This is a symptom of lung cancer.

2. Most patients with chest pain have chest pain of varying degrees. In the early stage of lung cancer, chest pain is not specific, chest tightness and distension, pain is not fixed, and it is mostly caused by qi stagnation; in the late stage, evil toxins penetrate into the chest, blood stasis occurs, and the pain is worse at night, fixed, like a needle or a thorn, and even lasts all day, the pain is unbearable, and even the bones and flesh are broken, the pain cannot be pressed, and the patient cannot turn over.

3. Fever is a common symptom of lung cancer, which is generally caused by yin deficiency and internal heat. Therefore, fever may occur in the afternoon or at night, or hot hands and feet, accompanied by irritability, night sweats, dry mouth, and dry throat. Fever can also be caused by internal obstruction of phlegm and blood stasis, and internal accumulation of toxic heat. The fever is strong and lasts for a long time.

4. Cough is the most common symptom of lung cancer. Patients often have paroxysmal choking coughs or obstructive coughs with high-pitched metallic sounds, without sputum or with only a small amount of white mucus sputum. If sputum stagnation turns into heat, the cough will intensify, and the sputum will be yellow, thick and sticky. If it lasts for a long time, both the lung yin and the lung qi will be damaged. Lung yin damage can be seen in coughing and hemoptysis; lung qi damage can be seen in low and weak coughs and shortness of breath. In the late stage of the disease, there will be evidence of weak coughs, sitting up and panting, hoarseness, cyanosis of the lips, puffy face and swollen limbs, which are evidence of the decline of qi, blood, yin and yang.

5. In the early stage of shortness of breath, the vital energy is not greatly weakened, and the symptoms are high-pitched and rough breathing, chest tightness and shortness of breath, which are mostly positive symptoms. In the late stage, the evil toxins are entrenched day by day, and the qi and yin of the lungs are damaged, so there is shortness of breath and wheezing with low and timid voices, chest tightness but not very urgent, because there is not enough air to breathe, so it is more severe when moving, and the patient likes to lie down and cannot tolerate work when quiet, and the breath is weak. This is the evil is strong and the vital energy is weak.
