Hi, I hope you don't mind me chiming in, I'm only a newbie, and never had a mammogram. Have you thought about thermography? It isn't painful and has few risks, and is very accurate being a full body scan. I'm 38, and this will be my preferred option rather than mammograms in the very near future. Here in Australia there are only a few places that offer thermography, but if you are in the US, you might have more options. If you would like to know more you could read at Dr Mercola's website, he has many good articles in regards to breast screening.
