Re underwires @socoda ..I checked on this and encapsulation and there is no research that causes this (confirmed also by my bc nurse ).. it's caused by infection not bras...but the myth continues. I'd imagine no wire for lumpectomy.... dependent on the location of the tumour and if pressure. ..that would be all. I couldn't consider wired bras initially after reconstruction due to matrix sling and scar along bra line. ..but 12 months on no issues. Radiotherapy maybe not so good whilst healing though.
