Abstract

Introduction: Breast cancer is a disease of global importance, characterized by abnormal growth of cells in the breast tissue, caused by different factors, which can be genetic, sporadic, hereditary and environmental. Objective: Analyze how the different factors are related to validity and non-validity of mammography in Chilean women within the age range between 50 and 69 years, in the year 2023. Method: Observational, analytical and descriptive study. In this way, the two groups to be investigated were analyzed: women between 50 and 69 years old with a current mammogram (control) and women who did not have it current (case), in order to relate various variables in relation to it. The total sample was 207 women, 119 controls and 88 cases. Results: According to the survey, women over 59 years of age with an odds ratio 1 (p < 0.87) had no differences regarding the validity of their mammography with those under 60 years of age, but not in women who do not worry about their health, which are four times more likely to not have a current mammogram (p < 0.81). On the other hand, women who did not have knowledge about the function of mammography are seven times more likely to not have a current mammogram. Conclusions: It is necessary to carry out a differentiated approach to each of the factors, both risk and protective, associated with the development of breast cancer.
