Analysis of radiological findings in treated breast cancer patients who had mammography in the state of Tocantins in 2023

Abstract

Objective: This study aimed to evaluate the results obtained in mammography in 2023 in women above 30 years old who
previously had breast cancer treatment in the state of Tocantins. Methodology: This is a quantitative and comparative
study of mammography results in treated breast cancer patients. It reunited data from the Cancer Information System
(SISCAN/DATASUS) using biological sex, time, and location of the exam as filters, evaluating new radiological findings.
Results: In 2023, 229 mammographies were done in women above 30 years of age who previously had breast cancer.
It was analyzed according to the Breast Imaging Reporting and Data System (BI-RADS). It was observed an expressive
number of BI-RADS 2 with a prevalence of 86.89%, followed by 8.73% represented by BI-RADS 0 and 3.05% Bi-RADS 4.
The categories BI-RADS 1, 3, and 5 presented the same percentage with only 0.43%. The age group with the highest number of radiological findings was between 60 and 64 years old, which constitutes 46 exams of the total studied; this number
had 37 classified as Bi-RADS 2, 3 as BI-RADS 4, and 1 as BI-RADS 5. The last one was the only finding of the sample that
is in this category, which represents 1.74% of the sample with suspect lesions. Conclusion: Screening the more considered risk population than usual is necessary in the face of the current prevalence of radiological findings. However, data
analysis shows a bigger concern among women between 60 and 64 years old, as there was a recurrence of highly suspect
findings only in this age group in 2023.
