Final answer:
A unilateral, single, mobile, firm, nontender solid breast mass should make you think of fibroadenoma.
Step-by-step explanation:
A unilateral, single, mobile, firm, nontender solid breast mass should make you think of fibroadenoma. Fibroadenomas are the most common benign (non-cancerous) tumors found in the breast. They usually occur in young women and often appear as a single lump that is painless and easily movable. Fibroadenomas may feel firm to the touch and are typically not tender.
