What are the early symptoms of lung cancer? These 4 symptoms are common in early lung cancer

According to relevant reports, lung cancer has become the number one killer of life and health. If the disease develops to the late stage, many lung cancer patients can only face death. Therefore, lung cancer patients should find early symptoms in time, which is very helpful for the treatment of lung cancer. So what are the early symptoms of lung cancer?

What are the early symptoms of lung cancer?

1. Cough. The early symptoms and signals of lung cancer must be remembered, such as abnormal cough. There are many reasons for coughing, so it is necessary to identify them. If there is no external environmental stimulation, no clear upper respiratory tract infection, and repeated coughing for unknown reasons, you should be vigilant. At this time, you need to take a chest X-ray. If conditions permit, it is recommended to do a chest CT. Of course, not all lung lesions are lung cancer, but it is necessary to clarify whether it is lung cancer.

2. Blood in sputum or hemoptysis. Lung cancer may cause blood in the early stage and hemoptysis. If you have this kind of symptom, you should be highly alert to lung cancer. Once a malignant tumor invades the blood vessels, it may cause blood vessels to rupture, resulting in blood in the sputum or hemoptysis. Therefore, if this symptom occurs, you should seek medical attention in time, and at the same time, you need to differentiate it from pneumonia, tuberculosis, bronchiectasis and other diseases to avoid misdiagnosis and mistreatment.

3. Swallowing difficulties. In the early stages of lung cancer, swallowing difficulties may also occur. This symptom is not common in lung cancer and is easily overlooked. A patient had swallowing difficulties, but multiple hospitals did not diagnose him. He was unable to eat until he came to Beijing with a chest CT scan. He was diagnosed with small cell lung cancer and mediastinal lymph node metastasis. This case reminds the public that if the cause of swallowing difficulties cannot be found in digestion, lung cancer should be suspected.

4. Chest pain. Lung cancer may also cause chest pain in the early stages. Chest pain is the first symptom of many lung cancer patients. If chest pain occurs without obvious trauma, it should be taken seriously. Lung cancer invading the chest wall can cause chest pain. As long as you pay attention, a chest CT scan can help with diagnosis.

Through the above text, I believe everyone knows and understands the early symptoms of lung cancer, so that they can pay attention to it in daily life and go to a regular hospital for treatment to avoid the late stage of development that becomes untreatable. I wish you a speedy recovery.
