Cancer is a global health problem that has a serious impact on individuals and society and is one of the most serious threats to public health. Cancer is the leading cause of death in most countries around the world, killing millions of people every year, and is an important obstacle to improving human life expectancy [10]. Breast cancer is an important factor affecting women's health, and early detection and treatment can reduce mortality. Color Doppler ultrasound and mammography are commonly used for breast cancer screening. The advantage of X-ray mammography is that it can observe the entire breast, retain clear images, facilitate comparative observation, and is not easy to miss diagnosis, but X-ray mammography may miss diagnosis of lumps with severe edema and lumps without obvious boundaries. Color ultrasound examination is simple and non-invasive, suitable for patients of any age, but color ultrasound examination on fat rich lesions, small lesions show poor, the overall image quality is not high. Therefore, in the process of urban breast screening, the combination of color Doppler ultrasound and X-ray molybdenum target is used for breast examination to reduce the rate of missed diagnosis and find each patient as early as possible.
The results of this study show that women who smoke are more likely to be diagnosed with breast cancer-related diseases, and the highest education level also has an indirect impact on the results of women's breast cancer screening through the intermediary variable of smoking. Women with lower education level are more likely to smoke, so are more likely to be diagnosed with breast cancer-related diseases. Uong et al. 's study also shows that women with lower educational level are more likely to smoke [11]. This may be because women with lower education level have lower awareness of the harmful health of smoking, the harm of tobacco to the human body has a lag, with the increase of smoking age, the harmful effect of smoking accumulation will be slowly highlighted, this disease will become more obvious with the growth of age, we should find more effective tobacco control measures to increase tobacco control efforts for young people.
A number of studies have also confirmed that smoking can increase the risk of female breast cancer and is a controllable risk factor for female breast cancer [12–14]. Lai et al. found that current smoking status was significantly associated with an increased risk of overall and cancer-specific death in women with breast cancer [15]. Jones et al. also showed that smoking was significantly associated with increased risk of breast cancer, especially for women who started smoking around puberty or menarche [16]. Studies have also shown that menopausal status plays a key role in the relationship between tobacco and breast cancer for all cancer subtypes. While smoking appears to increase the risk of breast cancer in premenopausal women, it may be associated with a lower risk of breast cancer in postmenopausal women who are overweight [17]. Therefore, the relationship between menopausal status and smoking status in women remains uncertain and more research is needed to confirm it. Van et al. 's study showed that when premenopausal and postmenopausal smoking adjusted for each other, breast cancer risk was significantly positively correlated with premenopausal smoking pack year, but negatively correlated with postmenopausal smoking pack year, both in a dose-dependent manner. The study highlights the importance of differentiating and adjusting for smoking across different life periods and suggests a dual effect of smoking on postmenopausal breast cancer risk [18]. Jordahl et al. showed that for women previously diagnosed with carcinoma in situ, drinking an average of at least one alcoholic beverage per day was positively associated with invasive breast cancer. After adjusting for alcohol consumption, smoking was not significantly associated with the risk of developing invasive breast cancer [19]. The study data of Wang Qian et al. showed that alcohol consumption was correlated with the occurrence of breast cancer to some extent, and this correlation was different with the dose, frequency, time and type of alcohol consumption [20], but the results of this study did not show the correlation between alcohol consumption and mammary gland related lesions in the female screening population. Smoking and drinking have a synergistic effect on the occurrence of cancer. Therefore, actively promoting tobacco control and alcohol restriction is an important measure to improve residents' health and effectively control the cancer burden.
Studies by Allahqoli et al. show that the highest rates of breast cancer are found in countries of higher socioeconomic status, such as those in continental Europe. Although the incidence of breast cancer is lower in countries with a lower socio-demographic index (SDI), secondary mortality from breast cancer is higher in these countries than in high-income countries [21]. However, the data in this paper is limited by the content of the questionnaire on the platform, and the lack of income-related data makes it impossible to classify the socioeconomic status of the population. As a result, the Anderson model lacks the variables of enabling resources dimension, which reduces the richness of the interpretation of the results, which is one of the limitations of this paper.
With the rapid aging of the population in China, the incidence and mortality of cancer will also rise [22]. The results of this study confirm the importance of a healthy lifestyle. Publicity and education on smoking cessation should be further strengthened, and smokers should be advised. Promote health by forming a healthy lifestyle in all aspects.
