Estimativa de risco de câncer radioinduzido correlacionado com doses efetivas em exames de mamografia

Abstract

The main purpose of this study is to evaluate the effective doses in mammography exams, establishing comparative criteria with recommendations from international and national agencies on the subject, assessing compliance with legislation aiming at ensuring patient safety and access to quality exams. In addition, to estimate the risk of radiation-induced cancer according to screening mammography programs. For this purpose, data on the mean glandular dose (MGD) of 194 mammographic images distributed in exams of 33 different patients were analyzed and data estimated, following the recommendation of the screening program of the Brazilian Society of Mastology (SBM) of the risk of radiation-induced cancer throughout the lives of the patients analyzed, with the XRay Risk Calculator. The analyses carried out were able to indicate doses negatively extrapolating the limits recommended by the agencies in the dose assessment and indicated a low risk ratio of radioinduced cancer in the risk calculation, indicating a beneficial relationship for screening mammography programs.
