Abstract: Objective To investigate the status of women's knowledge of prevention and treatment （KPT） of breast cancer and cervical cancer （referred to as “two cancers”） in Deyang, and to explore the related factors, so as to provide reference for better screening of “two cancers”. Methods The stratified cluster sampling method was adopted to select women from Deyang City as the research object to conduct an on-site questionnaire survey on the KPT of “two cancers” from June to September 2019. The descriptive epidemiological analysis method was used to analyze, and univariateand multivariateanalysis were used to analyze the factors affecting the KPT of “two cancers”. Results A total of 1 835 female residents in Deyang City were analyzed, aged 20-69 years old, with an average age of （42.36±5.22） years. The educational level was mainly in junior high school （653, 35.59%） and senior high school （634, 34.55%）. Urban residents accounted for 60.60%. The main occupation was enterprise workers （594, 32.37%）.The average total score of KPT of “two cancers” was （23.6 ± 5.3）, and the total awareness rate was 49.30%. There were 878 people who answered more than 60% of the “two cancers” prevention knowledge questionnaire correctly, and the understanding rate was 47.85%. The older female residents （OR=0.730） were less likely to understand the KPT of “two cancers”. The higher education level （OR=2.787）, urban residents （OR=5.512）, and their occupations were employees of enterprises and institutions or self-employed （OR=5.124, 1.713）, higher per capita monthly household income （OR=2.298）, history of breast disease （OR=1.775）, and history of gynecological disease （OR=1.320） were facilitating factors in understanding the KPT of “two cancers” among women. Conclusion The women in Deyang City have low scores of KPT of “two cancers”. We should focus on the elderly, low education level and low-income women in rural areas to strengthen the publicity and education of health knowledgeof “two cancers”.
