Hi Mic80, sorry this has happened to you. I had a similar diagnosis back in 2016. I was advised to have lumpectomy & sentinel node biopsy which came back positive so then had mastectomy & axillary clearance with a further 2 nodes positive, then chemo & radiation. The only real way to tell if the nodes have cancer is through a biopsy. 5 weeks ago I had a mastectomy on the other side with double DIEP and am very happy with results. It is very hard in the beginning with all the unknowns but you have a plan now & can move forward. If you decide to have recon in the future this can be done about 6 months after finishing radiotherapy. I was petrified of chemo but it wasn’t as bad as I imagined & worked all the way through with only 2 days off. Everybody reacts differently. I hope you have lots of support to help you through it. Let us know how you go xx
