This isn't TSA security procedure. Unfortunately, the OP didn't provide all of the facts, so it's hard to judge exactly what happened. Bottom line here is: there should never be a situation when a passenger must expose himself or herself to a screener. If so, then there is something seriously wrong, and I urge the passenger to submit a written complaint.

As for the so-called breast exam comment made by one of the so-called moderators: give it a rest. The screening methods used were carefully designed to clear the breast area with the back of the hand and in such a manner to minimize contact as much as practical. Calling it a breast exam suggests that screeners either grope women or get some sort of thrill out of performing this procedure. This may be popular on the playground with a bunch of giggling adolescents, but I thought this website was for serious discussion between mature adults who share concerns about airport security measures.
