What harm does lung cancer bring? 4 serious harms of lung cancer that you should know

Lung cancer is a tumor disease. Now many people are depressed because of lung cancer. Because the harm caused by lung cancer is so great, we have to feel a sense of fear about lung cancer. When patients suffer from this disease, many people will suffer a lot of harm. Let's take a detailed look at some of the harms of lung cancer!

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.

In the above introduction, everyone should understand the harm of lung cancer, so everyone should know that lung cancer cannot be ignored, so we should actively prevent it in our daily life, so as to avoid lung cancer. However, some people miss the treatment of lung cancer because they do not find the symptoms of lung cancer, so I hope everyone can learn more about it.
