What are the symptoms of lung cancer in the late stage? 3 symptoms of lung cancer in the late stage that you should know

Lung cancer is a relatively serious malignant tumor in our lives. Once it develops to the late stage, it will be life-threatening and is not conducive to the treatment of lung cancer. Therefore, patients also need to understand some symptoms of lung cancer in the late stage. Please allow relevant experts to introduce them to us below.

1. Lung cancer will cause hoarseness in patients in the late stage, 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.

Lung cancer is a relatively common type of cancer, and the number of lung cancer patients is increasing. Clinically, lung cancer can be divided into many stages. If it develops to the late stage, lung cancer is not easy to treat. Above are some symptoms of lung cancer in the late stage introduced by experts. I hope patients can pay more attention to them in their daily lives.
