What are the high-risk factors for lung cancer

What are the high-risk factors for lung cancer? Lung cancer is one of the malignant tumors with the fastest growing incidence and mortality rate, and it poses the greatest threat to people's health and life. In the past 50 years, many countries have reported that the incidence and mortality of lung cancer have increased significantly. Automobile exhaust, interior decoration, kitchen fumes, etc. are all high-risk factors for lung cancer. The trend of younger age of lung cancer is becoming more and more obvious, and the younger age of lung cancer is closely related to smoking.

How does PM2.5 cause lung cancer?

PM2.5 is a type of air pollution that can easily cause cancer in humans and is considered a common and major environmental carcinogen. The lungs are the organ most seriously affected by PM2.5. As the concentration of PM2.5 increases, the mortality rate of lung cancer will also increase relatively in the next seven or eight years.

It can break through the barriers of human nasal villi and sputum and smoothly enter the bronchi and alveoli. After entering the alveoli, the dust will be quickly absorbed and quickly enter the blood circulation without being detoxified by the liver, thus spreading throughout the body. The dust absorbed by the human body can damage the oxygen transport capacity of hemoglobin, causing the body to lose blood and cause diseases in various systems throughout the body. In addition to causing respiratory diseases including asthma, bronchitis, and more seriously lung cancer, it may also cause congestive heart failure and coronary artery diseases or lead to human poisoning, infant developmental defects, etc.

2Why do many women who don’t smoke get lung cancer?

It should be emphasized that people who inhale secondhand smoke or even thirdhand smoke (clothes with smoky smell, etc.) may also get lung cancer, or even worse. Women are one of the victims of secondhand smoke and even thirdhand smoke. For example, if the wife does not smoke but the husband smokes heavily, it is very likely that the wife will get lung cancer. In addition, the fumes produced by cooking, including various large and small particulate matter such as PM2.5, can all cause lung cancer.

Smokers are advised to quit smoking and smoke outdoors when necessary. Women are also advised to keep the range hood on for a few minutes after cooking to allow the range hood to fully absorb pollutants, and to clean the house and clothes regularly, especially when there is a strong smell of smoke.

Smoking is the primary factor for lung cancer. 85% to 90% of lung cancer is caused by smoking, and the mortality rate of lung cancer in male smokers is 8-20 times that of non-smokers. People who have smoked for more than 20 years, started smoking before 20 years old, smoke more than 20 cigarettes a day, or any of the three "20s" are very likely to get lung cancer.
