ABSTRACT

According to data in the statistics of the National Cancer Institute José Alencar Gomes da Silva (INCA) and the Ministry of Health (MS) estimates the occurrence of about 600 thousand new cases of cancer in Brazil in 2018. The precise number of the estimate is of 582.590 new cases of cancer being 282.450 in women and 300.140 in men of which female breast cancer reaches the number 59.700 new cases for biennium 2018-2019. In this article, we provide an overview of breast cancer statistics at Catanduva-SP in Brazil, including data on incidence, mortality, survival, and screening. Data from the years 2010 to 2015 of patients undergoing clinical therapy at Hospitals Padre Albino and Emilio Carlos, in Catanduva-SP, Brazil were analysed based on breast cancer incidence, demographic data, administered drug agents, medical history, clinical history, mortality and survival rates. The results were compared with those described by the INCA and data obtained in the scientific literature. In our studies, we showed that 25% of the cancer case treated during 2010-2015 at Catanduva-SP, were diagnosed as breast cancer and almost 99% were female, racially identified as caucasian and African (85 and 15%, respectively). The average age was 55 years old and 33.6% of these women had received mastectomy while 03 patients did not have a surgical intervention as part of breast cancer treatment. In addition, chemotherapy was used after surgery only in 6% of the patients. Finally, death number observed for breast cancer was 4.5%. Since 1990, breast cancer death rates have dropped by 34% and this decrease was evident in all racial/ethnic groups. Nevertheless, survival disparities persist by race/ethnicity, with which African American women having the poorest breast cancer survival when compared to any racial/ethnic group. Sustained and increased efforts to provide high-quality screening, diagnosis, and treatment to all segments of the population are needed to achieve continued progress in the breast cancer control.
