summary

Lung cancer is one of the most common malignant tumor diseases. The mortality of this disease is daunting. It has gradually occupied the top of cancer mortality. When it comes to lung cancer, everyone will think of smoking. "Smoking is harmful to health" is a warning sign that must be noted on the cigarette case. The harm of smoking to health is multifaceted, of course, the most direct one is to lung tissue. Passive smoking is as dangerous as smoking. Because the real damage to lung tissue, canceration is not nicotine in tar, but other carcinogens in tobacco, such as benzopyrene, nicotine just make smokers addicted, smokers exhaled smoke contains a lot of carcinogens. Therefore, people who work and live in the smoke around smokers for a long time are also at high risk of lung cancer. Besides smoking, urban industrialization and environmental pollution are also closely related to lung cancer. What are the symptoms of lung cancer infection? Let's talk about it

What are the symptoms of lung cancer infection?

Invasion of pleura can cause pleural effusion, often bloody. A large amount of fluid can cause shortness of breath. In addition, cancer invasion of the pleura and chest wall, can cause persistent severe chest pain.

The lung on the top of the upper lobe can invade and compress the organs and tissues at the upper thoracic orifice. For example, the first rib, subclavian artery and vein, brachial plexus, cervical sympathetic nerve, etc., produce severe chest pain, upper limb vein tension, edema, arm pain and upper limb movement disorders, ipsilateral upper eye and face ptosis, pupil narrowing, enophthalmos, facial anhidrosis and other cervical sympathetic nerve symptoms. After blood metastasis of lung cancer, different symptoms are produced according to the invasion of organs.

Finally, almost all lung cancer patients with regional spread have different degrees of shortness of breath. The normal tissue fluid produced by the lungs and myocardium is returned from the lymph nodes in the middle of the chest. If these lymph nodes are blocked by the tumor, the tissue fluid will accumulate in the pericardium to form pericardial effusion or in the chest to form pleural effusion. Both can cause shortness of breath. However, it is difficult to identify shortness of breath because many smokers have different degrees of chronic lung disease. In addition, due to the loss of respiratory function due to the growth of tumor in some lung tissues, the respiratory function of the lung is impaired, resulting in respiratory discomfort. At first, this kind of discomfort only occurs during exercise, and finally, it is felt even at rest.
