have current implants - do I choose lumpectomy/rad or mastectomy

Hi- I currently have implants and have been dx with Stage 1a Invasive Ductal Carcinoma. I am struggling with choosing lumpectomy or mastectomy because of the potential radiation effects on the implants. Can anyone comment on the mastectomy surgery compared to having a breast augmentation? As I know what breast aug was like. Just trying to get an idea of how bad a mastectomy is? Most plastic surgeons are telling me they won't put an implant back into a radiated breast so now I am back to struggling with a decision. Please jump in if you have feedback. Thank you
