Smoking plus the "four trends" are the main reasons for the surge in lung cancer

What is the cause of lung cancer? Lung cancer has almost become a killer of humans, with countless people dying from it every year. Do you know why? Smoking can make people mentally excited, and people love it, but they don’t know that smoking will push themselves onto a path of no return.

Over the past half century, the incidence and mortality of lung cancer have continued to increase, and there has been a trend of younger and more female patients. What is the reason for this? Relevant experts say that this is inseparable from smoking and the "four changes".

So what does smoking plus the "four changes" mean? They are population aging, urban modernization, rural urbanization, and the "delayed" occurrence of lung cancer.

"Smoking and passive smoking are the main causes of lung cancer." Lung cancer experts said. According to reports, there are 69 carcinogens in tobacco that are related to lung cancer. There are about 350 million smokers in my country, ranking first in the world, and 540 million people are exposed to secondhand smoke and smoke pollution. Studies have shown that in the attribution analysis of male lung cancer risk factors, smoking ranks first, about 75%, occupational factors are about 10.6%, and indoor radon exposure is about 0.15%; in the attribution analysis of female lung cancer risk factors, smoking accounts for 18.4%, passive smoking accounts for 11.1%, occupational factors account for 7%, and indoor radon exposure accounts for 0.15%.

In addition, environmental pollution cannot be ignored in inducing lung cancer. The pollution of indoor microenvironment such as the accelerated process of urban industrialization and modernization, the accelerated process of rural urbanization, and the unqualified indicators of indoor decoration materials have been proven to be closely related to the incidence of lung cancer.

The above is an introduction to the causes of lung cancer, and I hope everyone can pay attention to it. What the experts want to tell you is that in daily life, we must pay attention to our living habits and not let our bad habits lead to the occurrence of diseases.
