MSFinals-0133

A 28-year-old teaching assistant presents with a lump that she discovered in her right breast. She performed a breast check after reading an article about breast cancer and was worried to find a lump in the right breast.
The lump is painless, and she has no other accompanying symptoms. She has no family history of breast cancer.
Upon examination, there is a smooth 2 cm × 2 cm lump in the upper quadrant of the right breast. There are no skin changes overlying the lump.
What is the most appropriate course of action for this patient?
