A 45-year-old woman comes to the clinic due to a breast mass she noticed while showering. The patient is healthy, and she has no significant medical history. She is concerned because she recently found out she is a carrier of BRCA1 mutation. Her mother was diagnosed with breast cancer at the age of 48 and her sister at 46 years. The patient does not smoke or use alcohol excessively. Vitals are within normal limits. On physical examination, a well-circumscribed, soft non-tender mass is palpated in the right breast. There are no nipple or skin changes, and no palpable lymph nodes. A core-needle biopsy is obtained and reveals sheets of large anaplastic cells with dense lymphocytic infiltrates. Which of the following is the most likely diagnosis?
