After I had surgery, the report on the portal had quite a few errors. It referred to a "right breast" when the lumpectomy was performed on my left breast. And I still had the scars (plus a big L still written on my left shoulder) to prove it. So your confusing second diagnosis may be an error. I was in a position to write off the errors on my report as a "find and replace" problem, because they had already operated on the correct breast. Holiday weekends are the worst time to come across an alarming discrepancy like that.
