What are the specific symptoms of early lung cancer? There are six specific symptoms of early lung cancer

Clinically, most patients diagnosed with lung cancer are in the middle or late stages. At this point, the patient's survival is seriously threatened, which is really terrifying. This is mainly because the early symptoms of lung cancer are relatively hidden and are also very easy to be ignored by patients. So what are the specific symptoms of early lung cancer?

1. Superior vena cava syndrome: If the cancerous tumor compresses the superior vena cava, it will block the venous blood in the upper body from returning to the heart, causing swelling of the patient's face and neck. In severe cases, it can also lead to difficulty breathing, increased intracranial pressure, and unconsciousness.

2. Cough: Cough is the most common symptom of lung cancer. It is usually caused by tumors growing in the bronchi, blocking the flow of air or irritating the bronchial walls. It is one of the early symptoms of lung cancer.

3. Difficulty breathing: Early symptoms of lung cancer include lung collapse when the tumor blocks the bronchus, reducing lung capacity, causing chest tightness and difficulty breathing.

4. Bone pain: If the tumor metastasizes to the bones, it will cause bone pain or pathological fractures, which are also early symptoms of lung cancer.

5. Pleural effusion: If the tumor extends to the pleura, it will not only cause chest pain, but also malignant pleural effusion, leading to difficulty breathing.

6. Headache, vomiting, and visual impairment: If the tumor metastasizes to the brain, it will cause increased intracranial pressure, which may cause early symptoms of lung cancer such as headache, vomiting, and visual impairment.

Understanding the symptoms of lung cancer can help us achieve early detection and early treatment, which is very critical and should be given enough attention. Another point that needs to be noted is that the incidence of lung cancer is closely related to common factors in life, such as smoking, or inhaling secondhand smoke, which are the most critical causes.
