What are the early symptoms of lung cancer? There are four types

Everyone knows that when a disease is diagnosed, it will cause some symptoms in advance. Only through these symptoms can the patient go to the hospital for examination and diagnosis. The same is true for lung cancer. When suffering from lung cancer, the patient will experience symptoms such as coughing, blood in sputum, chest tightness, and shortness of breath in the early stage.

Lung cancer is one of the most common cancers and a malignant tumor disease. In recent years, the incidence of lung cancer has gradually increased. Early treatment is the best treatment period for this disease. Therefore, for a disease like lung cancer, early detection and early treatment are still necessary to achieve a cure. However, if you want to detect cancer early, you still need to understand its symptoms so that you can make a judgment. So what are the early symptoms of lung cancer?
Cough <br/>Lungs are important respiratory organs in the human body. When lung cancer occurs, it affects breathing, causing patients to have some respiratory symptoms. Cough is one of the most common symptoms of early lung cancer, characterized by unexplained irritating dry coughs. Some may also carry a small amount of white sputum. If you cough when you get up in the morning, you can find that there are even inconspicuous small blood clots or thin blood threads in the sputum. As the tumor grows, it may even block the trachea, causing tracheal stenosis. At this time, the cough will become more severe and persistent.
Blood in sputum <br/>The symptom of blood in sputum is mainly because the tumor tissue has a rich blood supply, so lung cancer patients will have persistent or intermittent coughing up blood when they have a cough. Most of the manifestations are blood in the sputum, which is bright red in color. When it is not serious, the amount of blood in the sputum is not large, and the cough sound is sharp and piercing. When the disease develops seriously, the cough sound will become sharper. As the disease progresses, there will be a lot of coughing up blood. At this time, you should go to the hospital for examination and diagnosis in time, so as to take treatment.
Chest tightness <br/>Chest tightness and shortness of breath are also common symptoms in the early stages of lung cancer. This is mainly because the lung cancer has developed seriously, causing the tumor to block the patient's trachea, or has already harmed the patient's pleura, so the patient has symptoms of chest tightness and shortness of breath. This symptom will be more obvious when lying down to rest, and the slightest movement will cause coughing. Although the chest tightness in the early stages of lung cancer is not obvious, there is also a feeling of chest tightness.
Shortness of breath <br/>If the patient has suffered from tracheitis or emphysema before, the feeling of chest tightness and shortness of breath will be more obvious. Therefore, if the patient has suffered from these two diseases before, when chest tightness, shortness of breath or worsening of breath occur, it is necessary to consider the possibility of cancer. Do not increase drug treatment as a result of the worsening of the condition. You must go to the hospital for examination and diagnosis in time to avoid delaying the disease.
