What are the symptoms of middle and late stage lung cancer? There are 3 common symptoms of middle and late stage lung cancer

Lung cancer is a disease with a very high incidence rate in my country. This disease causes great suffering to patients and their families. At the same time, many people have already reached the middle and late stages of the disease when they discover the disease, and treatment is very difficult. Let's take a look at the main symptoms of middle and late stages of lung cancer.

1. Hoarseness: Lung cancer develops to the late stage and can cause hoarseness in patients. This is mainly because the recurrent laryngeal nerve, which controls the left side of the human body’s voice, passes by the heart and then returns to the larynx due to large blood vessels. Therefore, if the tumor invades the left side of the mediastinum and compresses the recurrent laryngeal nerve, hoarseness will occur, but there will be no sore throat or other symptoms of upper respiratory tract infection.

2. Edema of the face and neck: Symptoms of advanced lung cancer can also be seen by observing the patient's face and neck, such as whether there is edema of the face and neck. In our human body, there is a superior vena cava located on the right side of the mediastinum, which transports venous blood from the upper limbs and head and neck back to the heart. If a malignant 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 edema of the face and neck, which needs to be diagnosed and treated in a timely manner.

3. Shortness of breath, pleural effusion: When lung cancer develops to the late stage, the condition is already very serious. It is common to have shortness of breath and pleural effusion. If there is regional spread, patients will also experience shortness of breath to varying degrees. The normal tissue fluid produced by the lungs and myocardium is returned by the lymph nodes in the middle of the chest. If these lymph nodes are blocked by tumors, these tissue fluids will accumulate in the pericardium to form pericardial effusions or accumulate in the chest cavity to form pleural effusions. Both of the above situations can cause shortness of breath.

This is all we have introduced about the symptoms of mid-to-late stage lung cancer. From this we can see that lung cancer is a serious disease. As long as we don’t pay attention to our bodies, we may get the disease. Therefore, for the sake of our health, we must do the most adequate preventive work.
