More questions than answers with LCIS

LCIS seems to be a bigger headache then other varying diagnoses. There are so many more questions to ask with such an illusive diagnosis. Personally, I went to my internist with a palpable lump, was then was sent for a diagnostic mammogram, and then a biopsy,then a diagnosis with LCIS; I was supposed to consult with a surgeon and then a day before my appointment , I was told that I need to go get an MRI of both breasts before the appointment. I guess since LCIS is usually diagnosed "by accident," versus presenting symptoms by itself (especially not with a palpable area). I had surgery almost 15 years ago on the right side and now it's the left side, both times in the exact same place and both times it presented with a palpable area. It's more than frustrating and scary. How am I supposed to proceed when there are more and more unknowns everyday? It has become an abyss of unknowns and I don't do well with those; I'm assuming none of us do. It's not an issue of insurance. So, what's with the curve ball? Has anyone been through anything like this? Or knows of it? I'm drowning with "what if's." Any suggestions or comments, PLEASE??!!??
