Abstract

With the development of imaging diagnostic tools, the detection rate of non-palpable breast tumors in early stages is increasing. The purpose of this study was to assess the role of ultrasound and mammography in patients with non-palpable breast tumors as well as to describe various clinical characteristics and the results of ultrasound and mammography. A descriptive retrospective study was conducted on 55 patients diagnosed with breast cancer with non-palpable tumors upon clinical examination at Hospital K from January 2018 to June 2023. The average age of the patients in the study was 53.4 ± 10.6 years old. 83% of the lesions were detected through regular health check-ups. Most patients had dense breast tissue on mammography, with type C accounting for 70.9%. The proportion of mass lesions detected through mammography was the highest, at 34.5%. On ultrasound, the majority of cases had lesion sizes ranging from 0.6 to 1.0cm, making up 43.63%. There were 19 cases (34.5%) of which the lesion size could not be measured through diagnostic imaging tools. Among cases with a determined lesion size, the average size was 0.9cm. The majority of patients had BIRADS 4 results, particularly BIRADS 4A, which had the highest percentage among all three diagnostic imaging methods. It is recommended to combine ultrasound and mammography with other diagnostic imaging methods such as breast MRI in patients with large or thick breasts. Diagnosing BIRADS 4A lesions should be cautioned to avoid missing non-palpable tumors.
