Background: Breast imaging plays a crucial role in the diagnosis and comprehensive assessment of breast cancer. Grey scale ultrasonography and mammography provide complementary information regarding breast tissue characteristics, while evaluation of the contralateral breast is essential to detect occult abnormalities. Understanding the association between imaging findings and demographic or reproductive factors may enhance diagnostic interpretation and patient management.
Methods: This analytic observational study employed a cross-sectional design and was conducted at the Department of Radiology, Universitas Hasanuddin Hospital, Makassar, Indonesia, starting from October 2024 until the required sample size was achieved. A total of 60 breast cancer patients who underwent grey scale breast ultrasonography and contralateral breast mammography were included. Demographic, reproductive, and clinical data were collected from medical records. Imaging findings were classified according to tissue type.
Results: Type C breast tissue was the most predominant pattern observed on both ultrasonography and mammography. No significant associations were found between age, age at menarche, body mass index, parity, menopausal status, or contraceptive use and imaging tissue types (p>0.05). Breastfeeding history showed a significant association with both ultrasonographic tissue type (p=0.021) and mammographic tissue type (p=0.011). Several variables demonstrated trends toward association with imaging patterns, although these did not reach statistical significance.
Conclusion: Grey scale ultrasonography and contralateral breast mammography reveal heterogeneous breast tissue characteristics in breast cancer patients. Breastfeeding history appears to significantly influence breast tissue patterns, emphasizing the importance of incorporating reproductive history into imaging interpretation and comprehensive breast cancer assessment.
