This study aimed to analyze the epidemiological profile of women diagnosed with breast cancer in the municipality of Cascavel, Paraná, Brazil, from 2014 to 2024. This was a descriptive study with a quantitative approach, based on secondary data obtained from the Hospital Information System (SIH/SUS) and the Outpatient Information System (HISTMAMA/DATASUS).

Most patients were female and identified as white, with histopathological grade II and III tumors being the most prevalent. Surgical treatment, particularly mastectomy, was the most frequently recorded approach, followed by outpatient therapies such as chemotherapy and radiotherapy. A slight decrease in deaths was observed in the final years of the study period. In conclusion, breast cancer remains a significant public health concern in Cascavel, Paraná, Brazil, highlighting the importance of strengthening prevention, screening, early diagnosis, and timely access to treatment strategies to reduce disease-related morbidity and mortality.
