Hi all my background is: diagnosed with stage 3 breast cancer in 2021. Had chemo Docetaxol and Carboplatin for 6 cycles alongside Herceptin and Zoladex. Then single Mastectomy with full node clearance. Cancer had been in 3 nodes and as I was told single cells in the breast. I had 15 sessions of radiotherapy. I then had Kadcyla for about 10-11 cycles. I have continued on Zoladex and started anastrozole in December 2021 which I am also still on. 

At the beginning of October I had a breast reduction on the none affected side. The tissue sample that was removed came back with no cancer in it. But then something was mentioned about Atypical changes in the breast. I was told this doesn’t have anything to do with risk or recurrence or anything and there’s no further follow up. 
I didn’t ask at the time and will ask when I’m next at the hospital but wondered if anyone knew anything about what this Atypical could mean or be caused by?
