5 causes of lung cancer, hard to prevent?

Lung cancer is the number one killer among cancers in my country, with the highest incidence and death toll. Globally, 90% of lung cancer is related to smoking, but many non-smokers still get lung cancer. Why? Today, we have invited experts to talk about the five main causes of lung cancer besides smoking.

1. Age

Lung cancer is rare in people under 40 years old, but it often occurs in people over 50 years old. We must admit that as we age, our cells will inevitably be damaged. As our body's immunity declines, the probability of getting sick will naturally increase.

However, age is only one of the influencing factors. It is not the case that you will definitely get cancer when you are older. Lung cancer is also closely related to many bad lifestyle habits. If we can change these habits, we can also help us stay away from lung cancer.

2. Secondhand smoke

Whether at home or in the workplace, passive inhalation of secondhand smoke will increase the probability of cancer. The "China Smoking Hazards Health Report" released by the Ministry of Health in 2012 also clearly tells us: there is no so-called safe level of secondhand smoke exposure, and any dose of secondhand smoke intake will have an impact. The more you inhale, the greater the danger, especially when someone is smoking indoors. No matter how many exhaust fans, air conditioners or other ventilation and air filtration devices are installed, non-smokers cannot be prevented from inhaling secondhand smoke.

3. Cooking fumes

Are you sure you're not kidding? No, Chinese cooking emphasizes color, aroma and taste. Deep-frying, stir-frying and dry-frying are often essential steps.

Studies have shown that women who cook every day have a two-fold increased risk of lung cancer. The cooking method also has an impact. Women who are keen on frying, deep-frying and stir-frying have a higher risk of lung cancer than those who cook. During frying, the oil temperature is high, which will produce some carcinogens (such as polycyclic aromatic hydrocarbons, dust particles, etc.).

Buy a range hood, it will take away those carcinogens that are lurking in your body. Improve your cooking methods and reduce high-temperature frying and stir-frying.

4. Air pollution

First of all, it is still difficult to clearly determine the relationship between lung cancer and smog. Various studies only tell us that lung cancer is related to smog, but how big is this correlation? No authoritative research has given a clear conclusion. In fact, compared with smoking or even cooking, smog is not the main cause of lung cancer.

Of course, we still need to prevent smog. If you stay indoors, you can buy an air purifier. If you go out, you can wear an anti-smog mask.

5. Radon

Most people may not have heard of radon gas. The radon gas we are exposed to usually comes mainly from soil, rocks and some decorative materials (such as marble, granite, etc.); if it is outdoors, the concentration of radon gas will be very low and will not have any effect on the body. In special indoor places, such as basements or rooms with decorative materials such as granite, it is possible that the radon gas concentration exceeds the standard, and it is necessary to pay attention to reducing indoor radon gas.
