Dear Donna
I know this has got to be beyond unnerving, i would be scared out of my skin, just at the idea...

Somehow, I have a feeling the biopsy will be fine... that you will be fine.
We do have to think positive, too, because it really can help.
I think you once mentioned you take calcium supplements, so calcium deposits would not surprise me that much. Their presence might simply be an indication that you are getting too much calcium, or not enough magnesium to balance it out.
Anyway, I will keep you in my thoughts and keep all my fingers crossed.
love and hugs to you
