What harm does lung cancer bring to patients? Four serious harms of lung cancer should be taken seriously

Everyone needs to do one thing, that is breathing, and everyone needs to rely on a part of the body to breathe, that is the lungs. Now there is a very serious disease that can seriously harm people's lungs, that is lung cancer. There are many lung cancer patients in the world, so what harm does lung cancer do to people?

1. If lung cancer develops and occupies most of the lung, it will seriously affect the respiratory function of the lung. Lung cancer extending to the pleura can cause chest pain and pleural effusion. Excessive pleural effusion compresses the lungs and can aggravate breathing difficulties, making it more difficult to treat than ordinary pneumonia.

Second, the abundant nerves in the bronchus are extremely sensitive. The cancerous masses that grow can stimulate the nerves in the bronchus and cause coughing. Everyone has this experience in life: a grain of rice falls into the bronchus, and after a few coughs, the grain is coughed out and the cough stops. However, the cancerous masses that grow in the bronchus cannot be coughed out, so there will be bursts of violent dry coughs that are difficult to stop. Sometimes the blood vessels in the bronchus are broken by coughing, and hemoptysis may occur.

3. Because the bronchi are blocked or semi-blocked by cancer, the original normal alveolar cysts no longer exist, affecting the exchange of oxygen and carbon dioxide. The patient will feel chest tightness and shortness of breath. The bronchial secretions, namely sputum, are not easy to be discharged, which can promote bacterial reproduction and cause pneumonia and fever. This type of pneumonia is called obstructive pneumonia.

4. If lung cancer spreads throughout the body and spreads to important organs such as the brain or liver, it can cause brain or liver dysfunction. If important organs of the human body are damaged too much, it is difficult to maintain a normal life, and even life is endangered. In addition, the metabolic products of cancer are different from those of normal tissues and have certain toxicity. Therefore, if the cancer is too large, it can endanger life even if it has not invaded other major organs of the human body.
