The main cause of lung cancer caused by smoking is that there are at least 60 known carcinogens and carcinogens among the more than 4,000 chemicals contained in smoke, among which the most harmful are nicotine (nicotine), tobacco tar and carbon monoxide, which are important risk factors for cancer.
So for women who don't smoke, why is lung adenocarcinoma also targeting them? This is because in addition to smoking, there are many occasions in our lives where we will be exposed to carcinogens!
【Kitchen fume】
The latest evidence-based medical data from 2016 show that oil fumes increase the risk of lung cancer in non-smoking women in China, and those who cook in poorly ventilated kitchens for a long time have a significantly higher risk of developing cancer.
When the temperature reaches 250°C, the decomposition of grease will produce oil smoke, which is only 0.01-0.3um in diameter, which is also one of the sources of PM2.5 production. When women are cooking, cooking fumes can be inhaled with breathing and deposited in the alveoli.
In addition, harmful gases such as carbon monoxide, sulfur dioxide, carbon dioxide, and nitrogen oxides released by fires such as coal, coal gas, liquefied gas, and natural gas in the kitchen are also carcinogens. Kitchen fumes also contain a carcinogen known as benzopyrene, which can cause damage to the chromosomes of human cells, and long-term inhalation can induce cancer in lung tissue.
Therefore, when we stir-fry, we should open the window for ventilation, and turn on the range hood at the same time, it is recommended not to turn it off immediately after stir-frying, but to turn it off for 10 minutes longer, which can shorten the time of oil smoke residue and reduce the damage to the lungs. At the same time, it is necessary to pay attention to the cleaning of the filter, blades and hood of the range hood.
