Please do not skip a year mom2. My breast cancer was very aggressive and had grown in the 11 months since my previous mammogram, when nothing was there. (We went over it with a fine tooth comb.) Two of my axillary lymph nodes were positive, so it had already spread locally. Had I waited another year, I might not be here today. Fortunately, we got it early and I had the most aggressive treatment available. My twins were just five years old at the time, so I know the feeling you're talking about.
I suggest people choose carefully where to get their mammograms. It's not something we often think about - a mammogram is a mammogram, right? Well we can see here, there are differences. I used to go to my health care group's radiology dept, but after a major screw up (that left me pretty devastated for almost a month), my oncologist had me go to a comprehensive breast center where, before I leave for the day, a radiologist has discussed my results with me and I leave with a copy. It is such a relief to walk out of there. This year I would up with an ultrasound but again, the radiologist did it herself and discussed her findings with me during the course of the exam, so I left with no worries. So if possible, really take a good look at where you get your mammograms.
