TECHTALK QUIZ: Breast Anatomy and Pathology

OBJECTIVES:


Every once in a while it is advisable to test ourselves on our retained knowledge. We work hard and often our information, hard won by hours of study, fades and gets lost. Here is a quick simple review of some of our breast anatomy and of a few of the common pathologies that plague the breast.

Good luck and I hope this turns out to be a good review for everyone. Please choose the BEST answer.
