I may be wrong in your case but many women (including me) had never had a proper bra fitting with a professional prior to bc. I used the same underwire bra after a mastectomy (no problem with scar line, no bruising etc) but was amazed when I consulted a professional fitter for a prosthesis to find a bra with no underwire (and a prosthesis pocket!) which fitted perfectly and supported well (E cup). May be worth consultation, if you are located where such can be found, and worth the trouble. Best wishes.
