The characteristics of the palpated mass suggest that it is a benign mass, most likely a fibroadenoma. However, since other breast lesions have similar characteristics, the lump needs to be evaluated via mammography. Hormone receptor status is used to determine if a malignant mass is stimulated to grow by estrogen or progesterone. A fine-needle aspiration may be done later on if there is reason to suspect a malignancy. Genetic testing for the BRCA genes would be done to determine a woman's risk for breast cancer, but this would not be done next.
