Four high-risk factors for lung cancer

Nowadays, the incidence and mortality of cancer in urban areas across the country have surpassed cardiovascular and cerebrovascular diseases and ranked first. In the ranking of malignant tumor deaths, lung cancer ranks first. When it comes to the causes of lung cancer, we have to mention the word "qi". In summary, there are four types of "qi" that can be attributed to high-risk factors for lung cancer.

There are hundreds of harmful substances in tobacco smoke. These substances, after being stimulated for more than 20 years, are the primary cause of lung cancer. More than 85% of lung cancer deaths are related to smoking.

Atmospheric air pollution and environmental pollution are important reasons for the high incidence of lung cancer in my country. Areas where PM2.5 seriously exceeds the standard are even more serious than tobacco, because PM2.5 can be directly inhaled into the alveoli, stay in the alveoli, and even enter the blood through the alveoli.

Indoor air Indoor air includes second-hand smoke, decoration pollution, kitchen fume pollution and gas. Gas itself is harmful, especially in the northern region, where it is used for heating, boiling water and cooking.
