Say What?

Last year I went thru the process of having a lump removed. I found the lump, had a mammogram, had a biopsy where they inserted a marker into the tumor to indicate the tumor had been checked out if we opted against surgery and eventually decided to have the lump removed. After the surgery it was nearly impossible to do a self exam of that breast because the tissue was so dense from the surgery scar tissue. I had just started doing self exams again when I found this new lump. I was devastated. We were just about ready to do another round of TTC when I found this lump. I really dont want to go thru another surgery. It was pretty miserable the last time. The fact that I produced two lumps in two years had DH and I seriously considering removing the whole breast to avoid going thru this again next year.
I went in for my mammogram yesterday. When she was done putting my girls in that vice-like machine that was so obviously designed by a man she asked me to wait while the radiologist reviewed the scans but was pretty sure I was going to need an ultrasound too. After a little while she came back out saying she needed more views and I was going ton have to get tortured by that damn machine again. While talking with her she asked why I was getting this lump checked out again. It turns out that the marker they put in during the biopsy was still there. I don't know what got removed during the surgery but at least a big portion of the lump was never removed. I have an appointment with the surgeon Thursday afternoon (her nurse called within two hours of me leaving the diagnostic center to schedule this appointment). I can't fathom what her explanation to leaving a major portion of a tumor inside me could be but thanks to her screw up I'm going to have to have another surgery, another scar, a more disfigured breast, and another recovery period.
I'm beyond pissed.
