“Objective: To quantify the cases of breast cancer in women under 40 years, hospitalized in the state of Tocantins and correlate them with national occurrence. Methodology: A retrospective epidemiological study based on hospital data from breast cancer in women less than 40 years registered in the Department of the Unified Health System (DATASUS). A comparative analysis and statistical was performed hospitalization rates in Tocantins and Brazil between January 2008 and December 2015 and held the chi-square test with 5% significance. Results: In the period analyzed, Tocantins has 338 cases of hospitalization for breast in women younger than 40 and Brazil, 50.420 cases. In this period Tocantins decreased by 56.92% in the number of hospitalizations for this disease, while in Brazil increased by 9.10%. During this period, Tocantins averaged 42 cases/year, and Brazil 6223.25 cases/year. The highest hospitalization rate in Tocantins took place in 2008 (n=65), and in Brazil was in 2013 (n=6.739). Statistically, there is an association between the age group affected and the hospitalization rate per year in Tocantins and Brazil (p<0.05). In 2015, 12% of women hospitalized in Brazil with a diagnosis of breast cancer had under 40 years, and in Tocantins, 14.28%. Over those eight years, 28.81 % of hospitalizations in Tocantins have given up in the age group 40 to 49 years, and in Brazil 27.30% to the age group 50-59 years. Conclusion: Corroborating the literature, the results suggest that age, especially after 40 years, is a risk factor for developing breast malignancy, considered low incidence in the age group 0-39 years. However, a significant increase was observed in the percentage level, with regard to these rates of hospitalization in Brazil over the years, while in Tocantins this rate is decreasing considerably.Key words: breast neoplasm; hospitalization; Women’s Health.”
