For number 3, I live in a rural part of Minnesota. It's rare to see breast implants even on adult women. I would notice pretty quickly if one of my clients had them as their breasts wouldn't "sit right" in some poses, particularly anything where they're on their back. For your other points, I'm talking about stick-skinny 17 year olds with very large breasts. Hormonal birth control could be part/all of the reason but it's not from weight gain anywhere other than their bust.
