Hi,

 I was diagnosed on 29/06/23 high grade DCIS with calcification Her2+3, oestrogen and progesterone negative . and have been offered mastectomy and immediate diep reconstruction surgery but no chemo as non invasive as far as the biopsy showed. I am also waiting on a genetics test to see if a double mastectomy is necessary.  I have 2 lumps in left breast 68mm and 17mm, lymph node was clear
my ongoing distress is about the waiting to see what final surgery I’ll be having and if the cancer is spreading while I wait  

Is it safe to wait this long as all I keep reading is how aggressive Her2 is. I probably won’t have surgery until mid September which will be nearly 12 weeks by then. It’s all I think about every day all day. 

please can you explain Her2+ and the grading and if its aggressive and if it’s safe for me to wait for surgery 

thank you so much for your help
