What are the symptoms of lung cancer?

Lung cancer is a common disease in people's daily life. Many people suffer from lung cancer because they do not treat some respiratory diseases in time. So, when you really get lung cancer, what are the symptoms of lung cancer?

First, lung cancer patients have edema in the face and neck. There is a superior vena cava on the right side of the mediastinum, 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, the jugular vein will initially become swollen due to poor blood return, and finally this type of lung cancer symptoms will appear.

Secondly, shortness of breath and pleural effusion are also symptoms of lung cancer. Almost all patients with advanced lung cancer that has spread regionally have shortness of breath to varying degrees. Normal tissue fluid produced by the lungs and myocardium is returned by the lymph nodes in the middle of the chest.

Finally, another symptom of lung cancer is chest pain. The chest cavity is a very complex space. Three-quarters of the lung surface is surrounded by the chest wall, which is composed of a thin layer of lining (parietal pleura), fat, muscle, ribs and skin in different proportions. Therefore, most patients with lung cancer that have regionally spread into the chest have symptoms of chest pain.

The above are the common symptoms of lung cancer. If you have similar symptoms to those of lung cancer, you must go to the hospital for examination and treatment in time and do not delay the disease.
