When it comes to lung cancer , many people's first reaction is that it is related to smoking. But the fact is not that simple!
Several factors inducing lung cancer
There are many causes of lung cancer. Smoking is certainly a major factor, but many people have not smoked, or even have not been exposed to second-hand smoke, and they will also suffer from lung cancer.
Why is this? What other factors can induce lung cancer, and how should we prevent it? -
1
Air pollution
Research has found that outdoor air pollution has become the second highest-risk factor for lung cancer in the world after smoking.
Air pollution mainly comes from transportation, indoor cooking and fuel combustion. The fine particulate matter in air pollutants and coal combustion products are the most dangerous, followed by the products after biofuel combustion.
Recommendation: When air pollution is heavy in autumn and winter, indoor air purifiers should be used reasonably if conditions permit.
2
Decoration pollution
Radon is a natural radioactive gas, colorless and odorless, widely present in building stones, such as marble, yellow granite and other materials. It is one of the factors of indoor air pollution.
When radioactive gas Radon gas enters the human body through the respiratory tract, the first one to be injured is the lungs.
Recommendation: Choose qualified building materials for interior decoration. The newly decorated house must be asked to ask the environmental inspection department to conduct indoor air quality inspection. Only after passing the inspection can you move in.
3
Food pollution
When making Chinese food, cooking methods such as frying, frying, and stir-frying are often accompanied by the generation of oil smoke.
These oil smokes often contain a large amount of inhalable particles and toxic and harmful substances. Long-term intake of oil smoke environment will not only aggravate the symptoms of respiratory diseases, but will also induce asthma, , inflammation, and even increase the incidence of cardiovascular and cerebrovascular diseases, and cancer.
Suggestion: Steam, boil and stew when cooking. When stir-frying or frying, you need to use a range hood reasonably and keep the room ventilated.
4
Working environment pollution
works in a heavily polluted environment. If the protective measures are not in place, the risk of cancer will also increase significantly.
For example, asbestos, the main component of building materials, is not harmful to the human body, but after being inhaled into the human body, it will be deposited in the lungs, stimulating the body to produce an inflammatory response, and then promoting the occurrence of lung tumors.
Suggestion: Take good work protection and avoid unnecessary health damage.
There are three ways to prevent lung cancer
1
Pay attention to early symptoms
. Cough lasts for 2 to 3 weeks or is ineffective in regular treatment (dry cough without a lot of purulent sputum)
. Blood in the sputum is included in the sputum Or cough up blood
3. After activity, chest tightness , can’t breathe, and continuous chest or shoulder and back pain
4. Long-term pneumonia or regular treatment is ineffective
5. Unexplained fever, hoarseness, fatigue, weight loss
. Control the above symptoms. If one or more of them are met, please go to the hospital to screen for lung diseases in time.
2
There is nodule You should check regularly
Lung nodules are benign and malignant, but as long as there are nodules in the lungs, you must check regularly.
The first time the lung nodule was found, it is recommended to have a review every 3 months. Nodules larger than 8 mm need to be enlarged biopsy .

High-risk populations do a key screening
I always hear some people say that they have a physical examination every year, so why do they become late after checking?
In fact, it is difficult to detect early lung cancer by chest radiographs taken during ordinary physical examinations. The gold standard for screening for lung cancer is low-dose spiral CT.
Generally speaking, those who meet the following conditions are high-risk groups for lung cancer screening must undergo regular lung cancer screening -
. Ages 50 to 75 years old.
. Merge:
- smoking ≥20 packs/year and quit smoking for less than 15 years;
- cancer history and family history;
- passive smoking;
- COPD pulmonary or pulmonary fibrosis ;
- contacts such asbestos, beryllium, uranium, radon, etc.
Tips for preventing lung cancer
Don’t smoke, don’t drink, maintain a good attitude, dietary rules, moderation, etc. can prevent the occurrence of lung cancer.
quit smoking, and it is not advocated to change to smoking electronic cigarettes in order to quit smoking. Quitting smoking means quitting smoking, and there is no need for any substitutes.
