My breast mass journey summary

I first found a small lump above my left nipple about a year ago and the nipple began retracting.  I kept an eye on it waiting for it to go away on its own.  Finally when my sister came to visit in May of last year I had her look at it and she freaked and told me to go to a Dr.  My regular Dr. was very concerned and had me go get a mammo and ultrasound.  The mammo picked up nothing and the ultrasound just revealed cysts.  Meanwhile I still had this hard mass above my nipple and it actually goes down and around it deep into the breast tissue.  I had a small core biopsy done by guided ultrasound and that came back negative.  Personally I think the Dr. took the sample from the wrong area.  The surgeon I saw pretty much dismissed it saying I was too young for cancer, no family history etc.  I asked him what the hard mass was and he said "I don't know but if it still bothers you come back in a couple months".  I was pretty disgusted by the whole was I was blown off and ended up loosing my health insurance anyhow.  Now that I have it back I went back to my PCP and she sent me to a specialist in Albany, NY.  She took one look at my breast (which has a nearly full nipple retraction by now) and said "Oh my goodness".  She did two needle biopsies right there and I have an MRI scheduled for this Monday (this was previously suggested by the last ultrasound reading but ignored by surgeon #1)  The biopsy came back with "atypical cells".  This mass fills my entire palm when I grasp it.  It is about the size of a softball cut in half.  Dr. is talking about doing a core biopsy after the MRI.
