Sentinel Node Biopsy First

that's a bugger, @Chrissy1121 that your choices appear to be somewhat confusing, even annoying ..... I can't give you advice as such - but waiting to see a plastic surgeon until May 2022 sounds extraordinary!  Are you able to be referred to another PS?

Waiting til after the chemo/surgery seems 'reasonable' tho....  All the best with your decision making xxx
