A 32-year-old female presents to your clinic with concerns over a recently
detected right breast lump. A mammogram performed revealed a right breast
mass measuring 3 cm with numerous microcalcifications suggestive of breast
cancer. During your discussion with the patient, she revealed that she had a sis-
ter who was diagnosed with breast cancer at the age of 39, a mother who
passed away with ovarian cancer at age 40 years, and a maternal aunt who had
both breast and colon cancer. Patient underwent an examination which
revealed a fixed and nontender breast mass on right side measuring 3 cm with
mild right axillary lymphadenopathy. No skin involvement is noted. A biopsy
was performed and revealed intraductal carcinoma.
