@kat919 - My mom's half-sister did the same thing. The family actually tried to talk her out of it at first, because we thought it was just too radical. But my mom's best friend is going through breast cancer treatments right now, and so now she understands better what her sister wants to avoid.
My aunt is actually quite thrilled with the result. She had reconstructive surgery. See, she'd been quite large-breasted and had had three kids, so holding up "the girls" was quite a task. Her implants are just B size and, frankly, have a life that a woman in her teens could envy!
