Abstract
ABSTRACT The purpose is to analyze the incidence rate of malignant neoplastic lesion by detection type and the proportional distribution of mammograms in women between 40 and 69 years of age from the State of Santa Catarina and from Brazil. This is a descriptive observational study of data from the Information Technology Department of the Unified Health System between 2009 and 2012 and the Brazilian Institute of Geography and Statistics. The greatest mammography coverage was in the group from 45 to 49 years, 22.2% in Brazilians and 23.1% in women from Santa Catarina. The greatest proportional distribution was 89.2% in Brazilian women between 40 and 44 years and women from Santa Catarina between 50 and 54 years. The incidence rates of malignant neoplastic breast lesion diagnosed by imaging increased in Brazil and Santa Catarina. In Brazil, in 2012, the highest detection was by palpation and, in Santa Catarina, by imaging. In conclusion, the screening is below the recommended, the higher proportional distributions of mammograms permitted a larger number of diagnoses of malignant neoplastic lesions and the application of mammograms as from the age of 40 years contributed to the diagnosis of breast cancer between the ages of 40 and 49 years.
Highlights
Mammogram screening aims for the early detection of breast alterations and the reduction of the mortality rates caused by breast cancer.[1]
The analysis proposed here can support the understanding of the importance of breast cancer screening per age range and how the population has adopted this practice, as well as the relation between having a mammogram and the detection of breast cancer in Brazil
According to the studies undertaken in the database of SISMAMA between 2009 and 2012, 8,960,659 mammograms were accomplished in Brazil in women between 40 and 69 years of age, of which 426,217 were undertaken in the state of Santa Catarina
Summary
Mammogram screening aims for the early detection of breast alterations and the reduction of the mortality rates caused by breast cancer.[1]. The International Agency for Research on Cancer published that, in 2012, approximately 1.6 million new cases of the disease happened globally, 522 thousand deaths and, among these deaths, almost 17 thousand cases involved Brazilian women.[2] For 2016, the Instituto Nacional do Câncer (INCA) has estimated that about 60 thousand new cases will occur in Brazil, two thousand of which in the state of Santa Catarina.[3]. According to the United States Preventive Services Task Force (USPSTF), the recommendations for breast cancer screening, mammogram screening every two years is more beneficial for women between 50 and 74 years of age, and that women between 40 and 49 years should make individual decisions about having a periodical mammogram or not, together with their physicians, taking into account the benefits and damages of this practice.[4,5] Mammogram screening can reduce the risk of death by the disease by up to 20%, corresponding to 15% for the population between 40 and years, 14% between and years and 38% for the population between and 69 years.[6]
