A 62-year-old woman undergoes a routine screening mammogram that reveals a new, highly suspicious 1.5-cm spiculated density with clustered microcalcifications in her left breast. She has no palpable masses or axillary lymphadenopathy on physical examination. Arrange the following interventions in the most appropriate chronological sequence for the evaluation and initial management of this patient's findings.
- 1Targeted breast ultrasound and diagnostic mammography
- 2Image-guided core needle biopsy of the lesion
- 3Breast-conserving surgery with sentinel lymph node evaluation
- 4Adjuvant whole-breast radiation therapy
Cevap
The correct sequence is: Targeted breast ultrasound and diagnostic mammography, followed by Image-guided core needle biopsy of the lesion, followed by Breast-conserving surgery with sentinel lymph node evaluation, and finally Adjuvant whole-breast radiation therapy.
The standard management pathway for an abnormal screening mammogram begins with diagnostic imaging (diagnostic mammography and ultrasound) to fully characterize the lesion and evaluate the rest of the breast and axilla. Once fully evaluated radiographically, an image-guided core needle biopsy is performed to establish a histological diagnosis and determine receptor status. Following the confirmation of an early-stage breast cancer, surgical resection (e.g., lumpectomy with sentinel node evaluation) is the primary treatment modality. Finally, patients who undergo breast-conserving surgery subsequently require adjuvant radiation therapy to ensure optimal local disease control.

The standard diagnostic and therapeutic sequence for screen-detected suspicious breast lesions begins with diagnostic imaging, followed by tissue biopsy, primary surgical resection, and finally adjuvant therapies such as radiation.
