Background: The incidence of breast cancer had increased around the world. More premenopausal women suffer from this condition with great economic and social impact. The objective of this study is to establish possible associations between lifestyle and the presence of breast cancer in premenopausal women. Methods: The study population was composed of 330 premenopausal patients younger than 55 years with breast disease, cared between 2013 and 2017 at the University Hospital Mayor Méderi. Two comparison groups were formed. Patients with a tumor diagnosed as malignant considering cases and control group of patients with a tumor diagnosed as benign. With factors associated significantly in the bivariate analysis (P andlt; .10), the hierarchically organized multiple regression model controlled by the confounding variables was constructed. The logistic regression model was adjusted by the age variable, to avoid residual confounder. Results: The population included 330 premenopausal women with benign and malignant breast disease: 134 cases and 196 controls. From the multivariate analysis, it was identified that the whole-grain consumption was inversely associated with presence of breast cancer (odds ratio [OR] = 0.579; 95% confidence interval [CI]: 0.339, 0.991; P = .046). On the other hand, consumption of fish was associated with the presence of breast malignancy (OR = 2.560; 95% CI: 1.200, 5.460; P = .015). Conclusions: Considering the epigenetic and multiomics individual profiles in the development of premenopausal breast cancer and its social and economic impact can be useful in development of modern clinical strategies with crucial interventions at the primary, secondary, and tertiary prevention levels for this disease.
