There is a significant relationship between kitchen fumes and the occurrence of lung cancer in women. In addition, the incidence of lung cancer among cooking staff in the catering industry is higher than that in general occupations, and the mortality rate of lung cancer among those who cook in the kitchen frequently is nearly one times higher than that of those who do not cook frequently. It is no exaggeration to say that kitchen fumes have become an invisible killer that threatens our life and health. A five-year epidemiological survey of lung cancer published in Shanghai not long ago found that young and middle-aged women are exposed to high-temperature fumes when cooking in the kitchen for a long time, which increases their risk of lung cancer by 2-3 times. The expert investigation concluded that because of the toxic fumes produced by high-temperature grease smoke during kitchen cooking, the local environment deteriorates and the toxic fumes irritate the eyes and throat for a long time and damage the cellular tissues of the respiratory system, which can easily lead to a high incidence of lung cancer if not protected. According to the group’s statistics, the incidence of lung cancer among women in Shanghai has increased rapidly in recent years, especially the number of women aged 40-50 who have lung cancer is close to that of men at 1:1. A 5-year follow-up etiological survey of lung cancer patients found that 70% of male lung cancer patients died due to smoking etiology, while only 18% of female patients died due to smoking or long-term passive smoking (husband smoking, working in a smoking environment) leading to lung cancer. Among the risk factors of lung cancer in non-smoking women, more than 60% of women are exposed to kitchen fumes for a long time and often feel irritated by smoke in their eyes and throat when cooking; 32% of women like to fry food with high temperature oil while the kitchen fume extraction facilities are aging, kitchen doors and windows are closed, and the small kitchen environment is heavily polluted by fumes; 25% of women have their kitchens connected to their bedrooms at home and rarely open the windows to cook in winter, so high temperature Fumes for a long time, even when sleeping also inhalation, toxic fumes long-term stimulation of the eyes and throat, damage to the respiratory system cell tissue. The survey shows that this cause is particularly prominent among middle-aged and elderly women with lung cancer in cities and towns, with 2-3 times more risk factors than normal people.
