Lung cancer is usually more common in middle-aged and older men, and those who develop the disease often have a long history of smoking or have some underlying lung lesions. However, with the development of society, more and more people are smoking, and it seems to be a “fashion” for women to smoke, and what is more worrying is that many minors also start smoking. In recent years, the incidence of lung cancer is also increasing, and there is a trend of younger age. In the past decades, lung cancer mostly occurred in men, so it is also called “male cancer”, the incidence of which is mostly above 40 years old, with the peak age of incidence between 60 and 79 years old, and the prevalence rate of men and women is 2.3:1. Lung cancer incidence is related to patient’s gender and age According to relevant data, the number of lung cancer incidence in Chinese men has increased by 26.9% in the last decade, while the number of lung cancer in women has increased by 30.5%. In recent years, according to the results of worldwide research studies, the overall lung cancer incidence rate of men exceeds that of women, and some studies have found that the incidence rate of lung cancer in men is even six times higher than that of women. Meanwhile, a recent survey found that men are 4.6 times more likely than women to have lung cancer between the ages of 45 and 64, and the difference is even more pronounced among older patients, with more male patients at higher ages. Squamous lung cancer is more common in men and adenocarcinoma in women The most common pathological types of lung cancer: squamous lung cancer and adenocarcinoma, and there are gender differences, with squamous lung cancer more common in men and adenocarcinoma in women. Earlier surveys in the United States showed that in the early 1970s, the incidence of lung cancer in men was twice as high as that of adenocarcinoma, while the incidence of adenocarcinoma in women was 30% higher than that of squamous cancer. In recent years, the incidence has been increasing worldwide, and the standardized incidence of lung adenocarcinoma in both men and women has increased significantly, with squamous carcinoma decreasing in men and increasing in women. Causes of lung adenocarcinoma in women Currently, lung adenocarcinoma accounts for about 30% of all lung cancers. Although there is a greater correlation between smoking and squamous lung cancer, relevant evidence shows that women who smoke are more likely to develop adenocarcinoma (especially young female lung cancer patients) and the lesions develop very quickly. So what are the causes of lung adenocarcinoma in women? 1.Smoking: Lung cancer and smoking are closely related, and the risk of lung cancer is greater for women than men. Women are more sensitive to tobacco carcinogenic compounds and are more likely to develop lung cancer than men under the same exposure. The increase in the number of women smoking in recent years and the presence of long-term passive smoking (with smokers in the family) may be an important reason for the increased incidence of lung cancer in women. Smoking is harmful to health, quit smoking as soon as possible, for the benefit of people and themselves! 2. Kitchen fume pollution: From the moment women become wives and mothers, they are busy preparing three meals a day in the kitchen, and lung cancer is closely related to air pollution, and kitchen fume pollution is very common in Chinese families. The proportion of lung cancer patients with a history of exposure to grease and smoke is higher among women than men. This is also one of the major reasons why non-smoking women in China suffer from lung cancer. To care for the women around you, you must install a hood in your kitchen and quit smoking as soon as possible! 3.Genetic factors: Race, family history and smoking have an impact on the development of lung cancer, and genetic factors are also the reason for the increased incidence of women. Special reminder: male lung cancer is mainly squamous cancer, but the incidence trend of squamous cancer is decreasing, while adenocarcinoma is increasing and the growth rate of adenocarcinoma is faster. In women, the main pathological type of lung cancer is adenocarcinoma, and the incidence rate is still increasing. The reasons for the increasing incidence of lung adenocarcinoma are unclear. Lung cancer incidence and age-related The incidence of lung cancer is still rising with age, rare under 30 years old, gradually increasing over 40 years old, and generally peaking at 65 to 70 years old mortality. However, as the smoking population becomes younger, one should be alert to the tendency of lung cancer occurrence in people under 30 years of age. An earlier large study of 20,561 lung cancer patients found that the age of onset of lung cancer was younger in women than in men, with an average age of 60 years for women and 62 years for men, and that younger lung cancer patients (<50 years) were more common in women than in men, accounting for 23.3% of all lung cancers in women and 12.6% of all lung cancers in men. In conclusion, there is a relationship between the incidence of lung cancer and the gender and age of the patient, and the incidence of lung cancer is higher in men than in women, and it is more pronounced in the older age group. However, the incidence rate of female lung cancer is higher than that of male in the young population. The incidence rate of male lung cancer tends to be stable or slightly decreasing, while the incidence rate of female lung cancer has an increasing trend. The growth rate of female lung cancer in Western countries may be related to female smoking, while most lung cancers in Chinese women are adenocarcinomas, which may be closely related to environmental pollution in the kitchen (combustion/oil smoke, etc.).
