help

Back in June 2014 I had a breast augmentation done (not cancer related) about a week after the surgery I noticed a lump right below my areola. It was hard bean shaped and felt smooth to the touch. In Aug 2014 I went in and had a Mam/us done I was told that it was a Bi rads 3 and to come back in 6 months. I went to see a Breast Specialist in November and they refused to biopsy it they laughed it off saying that it was most definitely Benign because I was only 30 and no Breast Cancer in my family. I went back in Feb 2015 and had a follow up ultra sound and was than told that it was Benign and classified this as a Bi rads 2. They told me just to come back in 6 months just for my own piece of mind because of my anxiety. I asked for a biopsy and the radiologist refused. I went in again 6 months later (Aug 2015) and had a third ultrasound now I have a Bi rads 4b classification with internal vascularity and not defined margins, I saw it and it looked like a puzzle piece on the ultrasound scree. I just had a FNA done last Friday and the fluid that came out was bloody.Im not sure what to do I know for sure that it is cancer and I am so pissed of at the system I wanted this lump biopsied a year ago and now it is probably spread.
