What are the symptoms of advanced lung cancer? You should know the two major signs of death before lung cancer

When it comes to lung cancer, everyone will definitely associate it with death. The mortality rate of lung cancer is very high, which is also an important reason why everyone is more worried about lung cancer. Before dying, lung cancer patients will have edema of the face and neck, shortness of breath and hoarseness. In the late stage of lung cancer, patients will have extrathoracic metastasis and lung metastasis.

Lung cancer is a disease with a very high incidence and mortality rate. Everyone should have some understanding of it. Once lung cancer patients develop symptoms, their bodies will show some abnormalities, which have a great impact on their health and life. In addition, the mortality rate of lung cancer is very high. If it is not treated promptly and effectively in the early stage, the condition can easily worsen or even lead to death. Today, experts will introduce the advanced symptoms of lung cancer and signs of death.

The symptoms of advanced lung cancer are divided into symptoms of extrathoracic metastasis and non-extrathoracic metastasis. The following is a detailed introduction:

1. Symptoms of extrathoracic metastasis of lung cancer: Lung cancer will metastasize along the patient's lymphatic vessels and blood vessels, usually to the lymph nodes in the neck, adrenal glands, brain, liver, and kidneys. Nearly 15% of lung cancer patients will experience symptoms of metastasis.

2. Non-metastatic symptoms outside the chest of lung cancer: Only 2% of lung cancer patients will experience non-metastatic symptoms outside the chest. The symptoms of non-metastatic symptoms outside the chest are relatively complex, and more systems are involved. The pathogenesis is unclear, so it poses a greater threat to patients.

The signs of death from lung cancer are as follows:

1. Edema of the face and neck: There is a superior vena cava on the right side of the human mediastinum, which returns venous blood from the upper limbs and the head and neck to the heart. If the lung cancer tumor invades the right side of the mediastinum and compresses the superior vena cava, the jugular vein will become distended due to poor blood return, and the patient will experience edema of the face and neck.

2. Shortness of breath: If lung cancer spreads regionally, patients will experience shortness of breath to varying degrees. 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 lung cancer tumors, they will accumulate in the pericardium, forming pericardial effusions, or accumulate in the chest cavity, forming pleural effusions, which will cause patients to experience shortness of breath.
