I had my mammogram a couple of months ago and was not offered that pad. Like Snowbunny, I don't find it THAT uncomfortable that I would need that. I would think they could get a better picture without a pad.
My doctor uses a new piece of equipment that gives you a 3-D picture and I was able to see the x-ray right away! It was so neat. They put a tiny band aid over any moles, etc. so the x-ray doesn't think it's a lump. I do have one small mole so they did that before the x-ray and I could see after why they had to do that with this 3-D equipment. It was a new experience for me.
But, Austen, I can't really help you about the pad. Just wanted to share this new experience.
