What are the early symptoms of lung cancer? There are three early symptoms of lung cancer

Lung cancer is a serious malignant tumor that threatens the life and health of patients at any time. We all know that if lung cancer is not treated in time, it will soon take the patient's life. So how can we find out that we have this disease as early as possible? We need to understand the symptoms of lung cancer.

Symptoms of advanced lung cancer:

1. Lung cancer in the late stage can cause hoarseness in patients, which is a common clinical manifestation. The recurrent laryngeal nerve that controls the left side of the voice function goes down from the neck to the chest, bypasses the large blood vessels of the heart and goes up to the larynx, thus controlling the left side of the voice organ. Therefore, if the tumor invades the left side of the mediastinum, the recurrent laryngeal nerve will be compressed, and hoarseness will occur, but there will be no sore throat and other symptoms of upper respiratory tract infection.

2. Patients with advanced lung cancer that has spread regionally will experience symptoms of shortness of breath and pleural effusion. Normal tissue fluid produced by the lungs and myocardium flows back through the lymph nodes in the middle of the chest. If these lymph nodes are blocked by tumors, the tissue fluid will accumulate in the pericardium to form pericardial effusion or accumulate in the chest cavity to form pleural effusion. Both of the above situations can cause shortness of breath.

3. Patients with advanced lung cancer may also experience facial and neck edema, so everyone should be vigilant. On the right side of the mediastinum is the superior vena cava, which transports venous blood from the upper limbs and head and neck back to the heart. If the tumor invades the right side of the mediastinum and compresses the superior vena cava, it will initially cause the jugular vein to swell due to poor reflux, and eventually lead to facial and neck edema, which needs to be diagnosed and treated in a timely manner.

Warm reminder: The symptoms of lung cancer during the onset of the disease are mainly the above points, you can take a serious look. Although the cure rate of lung cancer is almost zero at the current medical level. However, patients and their families should not give up the opportunity for treatment. Early detection of the disease is also very helpful for prolonging life. I wish you good health!
