The TSA has recently apologized to a breast cancer patient who was subjected to a pat-down. After walking through an image scanner at New York's JFK Airport, she was asked by a TSA agent to step aside to have her breasts examined. She offered to show her medical card which described the expanders and included her doctor’s contact information. But the request was denied and the examination was continued.
