We are all too familiar with various cancer-causing agents in our daily lives, and we try our best to minimize exposure. This includes limiting our intake of leftover food and processed meats, which may contain cancer-causing nitrites.
However, there is one carcinogen that many mothers come face-to-face with daily in their kitchens, and it often goes unnoticed: kitchen oil fumes.

In March 2024, the National Cancer Center released the latest figures on malignant cancer cases and deaths in China in the Chinese Journal of Cancer.
This report revealed that lung cancer has surpassed breast cancer as the most common type of cancer in women! By 2018, the incidence rate of lung cancer in Chinese women had reached 40.2 per 100,000 people (due to the large sample size, epidemiological information is usually delayed by 3-5 years, so the latest data available is from 2018)
Based on the 2018 survey data from the Chinese Center for Disease Control and Prevention, the smoking rate among women over 15 years old was only 2.07%. Further analysis showed that only 18.35% of Chinese women with lung cancer could be attributed to smoking or long-term exposure to secondhand smoke.

With such a low smoking rate, what accounts for the high incidence of lung cancer among Chinese women?
The Shanghai Lung Hospital also published an article in the Chinese Journal of Cancer, analyzing the pathological causes of lung cancer in women. It pointed out that hot oil fumes are a significant factor in female lung cancer. Approximately 60% of women with lung cancer had been exposed to kitchen oil fumes for extended periods, and the lung cancer rates were similar between those regularly exposed to kitchen fumes and regular smokers.
A related study published in the international academic journal Lung Cancer indicated that cooking oil fumes increased the risk of lung cancer in non-smoking women by 3.79 times. The International Agency for Research on Cancer has classified kitchen oil fumes as a Group 1 carcinogen.
In conclusion, kitchen oil fumes may be a critical factor contributing to the high incidence of lung cancer in women, but it has been overlooked for a long time.
