It is true that studies have shown that relatively young people, probably in the 30-50 age range, have a slightly higher incidence of lung cancer in women than in men. Based on existing studies, it is clear that 2 factors are more important: 1) environmental factors, although the proportion of female smokers is relatively small, women are more susceptible to lung epithelial cell damage from secondhand smoke and environmental dust haze compared to men. 2) genetic susceptibility is more important, referring to specific types of genetic mutations associated with lung cancer development, which are more likely to occur in women. In particular, mutations in genes such as EGFR, ALK, and HER2 are more common in women, implying a higher risk of developing lung cancer, especially lung adenocarcinoma. In addition, studies suggest that there may be a correlation with differences in hormone levels between men and women, especially high levels of estrogen may have some correlation with lung cancer, but its controversy is not particularly definitive, and these are the results of current studies on the relative susceptibility of young women to lung cancer.
