What causes lung cancer?

There are many factors that cause lung cancer, including environmental pollution, occupational exposure, and chronic lung infection. After the onset of the disease, patients will have irritating coughs, blood in sputum, wheezing, chest tightness, shortness of breath, etc. Symptomatic treatment should be strictly carried out according to the severity of the disease, and daily care should be done to avoid the continuous aggravation of lung cancer.

1. Environmental pollution: Living in an environment with severe air pollution for a long time, or being exposed to passive smoking or inhaling highly irritating gases may lead to lung cancer.

2. Occupational exposure: Frequent exposure to harmful substances such as asbestos, nickel, coal tar, trichloromethyl ether, arsenic, and frequent exposure to ionizing radiation and microwave radiation can cause repeated damage to lung tissue and cause lung cancer.

3. Chronic lung infection: If chronic diseases such as tuberculosis or bronchiectasis are not treated in time, the lungs will be repeatedly infected by inflammatory substances, and the chance of cancer will increase.

In addition to the above common causes, factors such as family heredity also play a role in promoting the onset of lung cancer. Patients can choose radiotherapy, drug therapy or surgical treatment according to the severity of the disease. During this period, they should pay attention to quitting smoking and drinking, and maintain a healthy and light diet, which is very helpful for the treatment and control of lung cancer.
