6 major health hazards of lung cancer

Lung cancer is one of the most common malignant tumors, and its mortality rate ranks first among cancer deaths in cities in my country. The causes of lung cancer are complex and may be related to smoking, air pollution, long-term exposure to certain chemical carcinogens and radioactive substances in daily life. As a malignant tumor, lung cancer is extremely harmful to human health:

1. The growing cancerous mass stimulates the nerves in the bronchus, causing severe dry cough and sometimes coughing up blood.

2. The bronchi are blocked by tumors and the original normal alveolar cysts no longer exist.

3. If lung cancer spreads to the pleura, it can cause chest pain and pleural effusion, which can compress the lungs and aggravate breathing difficulties.

4. If lung cancer develops and occupies most of the lungs, it will seriously affect the respiratory function of the lungs.

5. The metabolites of cancer are different from those of normal tissues and have certain toxicity. Therefore, if the cancer is too large, it can still endanger life even if it has not invaded other organs of the human body.

6. If lung cancer spreads throughout the body, to important organs such as the brain or liver, it can cause brain and liver dysfunction. If important organs are damaged too much, it will be difficult to maintain a normal life, and even endanger life. If it spreads to bones, it can cause severe bone pain and pathological fractures.
