A 52-year-old G0P0 presents to her gynecologist for an annual exam. The patient notes that she recently felt a lump in her right breast, and it has persisted for several months. She has not noticed any abnormal breast discharge or skin changes, and the lump is not particularly tender. The patient also reports feeling especially sweaty in the last three months and occasionally having sudden heat waves. As a result, she has been increasing her use of antiperspirant in the axilla. The patient has no medical problems, has a BMI of 18.4 kg/m^2, and takes no medications. She underwent menarche at age 16 and had a levonorgestrel intrauterine device inserted three years ago due to heavy menstrual bleeding. The patient has now been amenorrheic for two years. She has a family history of breast cancer in her cousin at age 61 and hypertension in her father, who is 91. At this office visit, a 3x3 cm lump is palpated in the upper outer quadrant of the right breast. It is firm and not freely mobile. Ultrasound and mammogram are shown in Figures A and B.
