A 45-year-old Black woman presents to her ob/gyn for her annual wellness visit, reporting a lump in her left breast that she found during self-examination at home. The mass is painless. Physical exam confirms presence of a bulky, soft, palpable mass in the left breast, which is visible as slight protrusion/edema on the lower outer quadrant of the left breast. Her only other complaint is increased fatigue over the past several months. Her medical history is unremarkable. There is a positive family history of breast cancer — her mother was diagnosed with breast cancer at age 47 years. A diagnostic mammogram reveals a lobulated mass; ultrasound shows a hypoechoic mass with a thick echogenic halo.
