As the world's largest cancer, lung cancer is really not a waste of time.
According to data from the National Cancer Center, the incidence, mortality and lung cancer of malignant tumors are ranked first, and in 2017, the number of lung cancer patients in China reached 800,000 and the number of deaths was 700,000.
It is expected that in 2025, the number of lung cancer patients in China will reach 1 million, and it will soon be crowned the title of "lung cancer power".
Many well-known people have also died prematurely due to lung cancer.
For example, teacher Zhao Lirong, a year after taking the stage in 1999, died of lung cancer a year after taking the stage to the Spring Festival Gala;
For example, Ouyang Peishan, the actor of Huang Rong in the 83rd edition of "Divine Eagle Man", only had more than 3 months from the detection of lung cancer to his death.
Lung cancer, now starting to find women who don't smoke?
The biggest carcinogenic factor of lung cancer is tobacco exposure, more than 90% of lung cancer has a history of smoking, but in recent years, the data show that more than 1/3 of female patients, non-smoking women have a very high incidence of lung cancer.
Similarly, this phenomenon has also appeared in Singapore, Malaysia, the United States and other Chinese women.

Obviously smoking increases the chance of lung cancer, why does lung cancer start to find Chinese women who do not smoke?
First, long-term exposure to kitchen fumes
Experiments have proved that the kitchen fumes contain a large number of harmful gases, often contact with kitchen fumes, will bring a huge burden to the lungs, which is also one of the important causes of lung cancer.
According to statistics, the carcinogens breathed in the oil smoke, especially the high-temperature oil smoke produced by crude vegetable oil, soybean oil and corn oil, contain benzopyrene, butadiene, phenol, etc. have been confirmed to be mutagenics and carcinogens.

According to a British study, in a poorly ventilated kitchen, using a stove with inefficient combustion to make a meal absorbs harmful substances equivalent to smoking two packs of cigarettes.
When making fried food or stir-frying in hot oil, PM2.5 in the air also increases dramatically. These can cause damage to the lungs and increase the risk of cancer in the long run.
Second, long-term depression is not good
Chinese medicine believes that people's emotions affect the internal organs of the body.
Long-term depression, depression in the mood, will lead to gas in the chest and lungs, at this time, people's breathing will become rapid, alveoli has been in a state of expansion, a long time, will lead to lung function damage, serious and even induce lung cancer.
Western medicine believes that although mental and psychological factors cannot directly cause cancer, they often use a chronic stimulus to reduce the body's immune capacity and increase people's risk of cancer.
Third, second-hand smoke
Nearly 740 million non-smokers in China are currently affected by second-hand smoke, including 180 million children.
At present, there are more than 300 million smokers in China, which means that one person smoking, in addition to endangering themselves, will also endanger the health of at least two people.
When second-hand smoke is exposed, tobacco residues tend to react with other common pollutants in the air, gradually forming 11 highly carcinogenic substances, which will also increase the chance of lung cancer.

How can I stay away from lung cancer?
1. Keep away from second-hand smoke
Many people know that smoking is one of the important factors that lead to cancer. However, I do not know that long-term exposure to second-hand smoke will also increase the risk of cancer.
Second-hand smoke contains many particles with a diameter of less than 2.5 microns and other harmful gases, which will be suspended in the air and bring a great burden to the lungs, especially in closed rooms, which are more harmful.
Therefore, if you want to raise your lungs, you must stay away from second-hand smoke.
2. Strengthen exercise
Exercise can effectively increase cardiopulmonary function.
The data shows that people who regularly participate in physical exercise will have a great increase in lung capacity, and in the process of exercise, people can better discharge turbidity, suck fresh air into the body for circulation, so as to get up and nourish the lungs.
3. Install a smoke oil machine
Studies have found that women who do not use a smoke oil machine in the cooking process have a 3.2-12.1 times higher risk of lung cancer than ordinary people.
Therefore, the kitchen is installed with a smoke oil machine to ensure that the kitchen is ventilated smoothly, and after each cooking, let the hood continue to work for 10-15 minutes until the kitchen fumes are completely dissipated.
At the same time, when cooking, control the oil smoke, avoid heating the oil until it smokes before starting to stir-fry, so as not to produce a large number of harmful substances. In addition, reduce the repeated use of oil, in the cooking also try to take the steaming method, reduce the frying, stir-frying and other ways.
