I have had this happen to me as well.
When they first spotted it, they brought me back in for magnified mammograms. Results inconclusive.
So they brought me in for a mammotone biopsy. That’s where I was strapped down to a mammogram machine, with my boob in a vise, and then they shot a needle into my boob to take a core sample of the microcalcification. Painful and awkward as hell, but the process, from a science-minded point of view, was kind of cool. They also shot a tiny metal dog tag into my boob to mark the microcalcification and track it over time, to see if it grew. Results inconclusive.
So then they sent me to surgery for a wide excision biopsy. This was full-on surgery, but outpatient surgery. They took me to mammo (again – I had about 20-30 films taken throughout this process, over about six weeks. I was afraid all that radiation exposure would give me thyroid cancer, but they assured me it’s fine. I have my doubts. Radiation exposure is cumulative.) and shot a guide wire down to the little dog tag they’d previously shot into my boob. Surgeon cut down the guide wire, used a melon-baller (not really) to lop out the microcalcification, left a big dent in my left boob, and closed up my nipple. Yes, he went in at the nipple line. That really, seriously sucked to recover from. Results: benign. Except for the dent in my boob where there was tissue that is now missing.
I went through all that – with no partner or support of any kind whatsoever – completely terrified, only to find out it was just a teeny tiny spot of calcium. And now I have to see that surgeon every six months until five years are up. I’m in year three since that surgery. All subsequent mammos have turned up nothing. I never even had cancer, but I am treated like a BC survivor at the mammo place and at the surgeon’s office, which is also awkward and uncomfortable. I don’t deserve that kind of fawning attention – I haven’t been through jack compared to an actual BC survivor.
All I can say is chances are, it’s nothing, but it is impossible not to be scared shitless until you get a real lab result that says so. And there is a very small chance that it’s something, so you have to go through all that. While you are supporting your wife through all this, be sure to not let her jump to step 267 (“OMG, I’ve got to update my will since I’ll be dying of breast cancer next week!”) when you are still on step 2. It’s very easy to go there and let your brain make up scenarios. Maybe it’s easier without support and if I’d had somebody in my corner, perhaps I wouldn’t have let my imagination run so wild. What I made up in my head was 1,000 times worse than what reality turned out to be. So if you can keep her talked off the ledge and be her rock, good on you.
It also doesn’t hurt for you (not her – that was a bad idea) to do some googling about the diagnosis and next procedure. I got numbers that helped me talk myself down off the ledge because the chances of having breast cancer were extremely small.
My thoughts and atheistic “prayers” will be with you both.
