A 19-year-old woman noticed a mass in her left breast 2 weeks ago while doing monthly breast self-examination. Her mother died of metastatic breast cancer at the age of 40 years. Examination shows large dense breasts; a 2-cm, firm, mobile mass is palpated in the upper outer quadrant of the left breast. There are no changes in the skin or nipple, and there is no palpable axillary adenopathy. Which of the following is the most likely diagnosis?
(A) Fibroadenoma
(B) Fibrocystic changes of the breast
(C) Infiltrating ductal carcinoma
(D) Intraductal papilloma
(E) Lobular carcinoma
--------------------------
A vs B?
I got it right, but was having hard time picking one so I went with A, which turned out right, but now I need to know why A and not B? |
