It’s not overkill.I had a recurrence 7yrs after my lumpectomy and radiation so had to have a mastectomy and chemo.Reconstruction becomes very limited because of radiation treatment.
I’ve remained lopsided for 9yrs- I don’t like it but I’m used to it and at least I’d see a recurrence.I wear a prosthesis and you’d never know and once I’m dressed I forget about it.I’m grateful to be cancer free for 9 yrs and hopefully, that’s the end of bc for me.Hope your surgery goes smoothly and come back here if you have any questions.
