Objective: This study evaluates the role of 3D breast ultrasound in diagnosing breast cancer, particularly in a bilateral case, comparing it with traditional diagnostic methods.
Methods: A 55-year-old female patient was incidentally diagnosed with breast cancer during screening due to an elevated CA 15-3 index. Although ultrasound and clinical examination did not detect tumors, mammography and MRI identified BIRADS 4 and 5 lesions. A subsequent 3D ultrasound revealed small lesions that previous methods missed. Core biopsy confirmed ductal carcinoma in situ in the right breast and invasive ductal carcinoma in the left breast.
Results: 3D ultrasound effectively detected small lesions in dense breast tissue that were missed by mammography and traditional ultrasound. The detailed imaging allowed for more accurate diagnosis and guided surgical planning. Postoperative diagnosis confirmed bilateral invasive ductal carcinoma.
Conclusion: 3D ultrasound offers significant advantages in breast cancer diagnosis, particularly for patients with dense breast tissue. Its ability to provide detailed imaging helps detect small, non-palpable lesions, enhancing diagnostic and treatment outcomes.
