I remember your thread from a couple of weeks ago. I'm sorry you're still having such anxiety over this (it does sound like it's progressed to panic). I think when this is over, it would be really helpful for you to see someone to help you work this through and give you coping strategies for other situations in the future. However, I can totally see why you'd feel worried about having cancer yourself having lived through what you did with your mother. My sympathies once again.
I hesitated to post, because as you can see from my signature, I'm a breast cancer survivor (6 1/2 yrs) so have been through what you're feeling - and more. (And I live with worry every day, but thankfully not as much as it used to be. Being a nurse sometimes makes it worse as I see the worst of the worst every working shift.) But the reality is that breast cancer is out there, we unfortunately can't make it go away.
I agree with the others that if it were something serious, you would have gotten a call and had further testing scheduled by now. When they saw a very suspicious spot on my mammogram, they sent me immediately for an ultrasound down the hall, then the radiologist came into the room afterward to meet with me and to say I needed a biopsy right away. When he added, "We have an opening tomorrow" I knew it was bad.
But guess what. Here I am, still here Dis-ing, still loving life, still being the best mother to my children and the best nurse to my patients that I can possibly be. Along with milliions of other Survivors. Surviving cancer helped me see things from a different perspective that I might not have otherwise seen. So, although we know that people do die of breast cancer, far more survive, so even in the worst case scenario, odds are (as I said in the other thread) that you'd be just fine.
With that said, I bet you're going to ultimately have a negative reading. Part of what they want to do on your first mammogram is to establish a "baseline" reading for which to compare future mammograms, therefore it has to be an excellent reading. They probably just want to redo it so that there is absolutely no question about your readings that may have been of inferior quality for whatever reason.
You hang in there.
PS on the Breast Cancer Survivors thread here, we have a saying (courtesy of NHAnn's DH):
Don't bleed until your shot. I think it applies here.
And binny, I LOVE your Daddy's saying, too!
