64-Year-Old Female with Palpable Lump in Left Breast
A 64-year-old woman is referred to an oncology clinic after discovering a palpable lump in her left breast about 3 months ago. Mammography and ultrasound showed a 5.1 cm mass and enlarged ipsilateral axillary lymph node.
Core needle biopsy revealed IDC, 90% estrogen receptive positive, 90% progesterone receptor-positive, and HER2 negative. Her axillary lymph node tested positive for adenocarcinoma. Positron emission tomography revealed multiple pulmonary nodules, ranging from 1 cm to 2 cm, and an enlarged mediastinal lymph node — all suggestive of metastatic activity. A core needle biopsy of one of the pulmonary nodules confirmed metastasis, 85% ER-positive, 90% progesterone receptor-positive, and HER2 negative.
The patient is in good spirits and denies dyspnea or pain. She is a high school teacher and reports no difficulties at work. She has no comorbidities and is on no medication. Her metabolic panel and CBC are unremarkable.
