I totally empathise and relate to this. I was completely traumatised with a mammogram years ago. My breast was clamped so tight i thought it would pop; literally. I too felt I was a being 'wet', even though I know I have a high pain threshold. I felt utterly violated; I remember saying stop, but the operator continued because it was 'nearly finished'. Held myself together until I left the (mobile, car park) unit then cried for...hours.
Heartfelt admiration for you taking forward your situation. Thank you. Despite feeling the responsibility for safety of other women, it took me a couple of years to address my trauma formally - with an amazing, empathetic hospital mammographer.
