I've had a mammogram today and as per the previous ones I've had it hurt like hell! I would generally say I've got a pretty good pain tolerance. I posted on Facebook as a reminder for my friends to do theirs if it's due etc. Some women say it doesn't hurt at all, but honestly it's horrible for me, one time I actually cried. Interested to know others experience. For what it's worth I'm about a small D large C cup. My sister who is way bigger than that was one that said it never really hurts.
