A 55-year-old woman presents to the clinic after discovering a firm, painless lump in her right breast 2 weeks ago. Physical examination reveals a 2.5-cm hard, irregular, and relatively fixed mass in the upper outer quadrant of the right breast. There is no nipple discharge, skin dimpling, or palpable axillary lymphadenopathy. Arrange the following diagnostic and management steps in the most appropriate chronological sequence for this patient.
- 1Diagnostic mammography and targeted breast ultrasound
- 2Image-guided core needle biopsy of the mass
- 3Pathologic evaluation for estrogen, progesterone, and HER2 receptor status
- 4Breast-conserving surgery with sentinel lymph node biopsy
Cevap
The correct chronological sequence is: diagnostic imaging, followed by core needle biopsy, followed by pathologic receptor testing, and finally definitive surgical excision.
The standard of care for a suspicious palpable breast mass in a woman over 30 dictates a stepwise approach. Non-invasive imaging (mammography and ultrasound) is performed first to characterize the extent of the disease. This is followed by a minimally invasive core needle biopsy to confirm malignancy. Once cancer is confirmed, the tissue is tested for receptor status to guide systemic therapy. Finally, definitive local surgical management (such as lumpectomy and sentinel lymph node biopsy) is executed.
