You go in and you take your bra off and stand at this machine as the nurse tells you, and obviously at different angles and obviously your boobs get rather squashed. Sometimes it hurts, it's tender but not always. Last time I didn't feel anything, I was most surprised, it was very good.

Is there ever any embarrassment involved, some people say they feel it's embarrassing?

I don't think so, when you get to my age, when you've had three children, I don't think you, and they're all ladies and they're all very pleasant and they're all very gentle [laughs].
