2 Lumpectomy with unclear margins, what should I do?

So Ive had 2 lumpectomies with reconstruction in the past 3 weeks. Unfortunately both procedures produced unclear margins. There is only about 2.5mm of cancer left from what my surgeon had stated front the last procedure. She's recommending that I undergo stronger amounts of radiation to diminish the rest of the cancer that is still there.

Has anyone gone through the same thing and if so what option did you choose? Did you choose to go with radiation and if so what were your ending results? Or did you push for another operation?

Also I am stage IV with one single bone met. So I guess that plays a big role in it all.
