Sorry for not reading your post fully, but I can tell you for the last 16 years I have had to have 2 mammograms vs the usual once a year most woman get, I have had numerous amounts of tumors and cysts (thankfully benign)and I really can understand your fear and frustration.
I happen to be one of those that have had to have ultrasounds, mammograms, biopsies, etc. to confirm crap, the best I can say is go for your mammograms, go for the ultra sounds, surgery,etc. in the very long run it removes the prolonged stress of "should of gone, what if?, when?, you know all those additional things that plague us.
Okay, bottom line, I wish yoou lots of love and luck with this, but do not let it go too long.
