Chances of radiation working when chemo doesn't?

Long awful story.

Last year, following a lumpectomy, I did not get the oncotype dx score done. (I asked and it's the standard of care.) my former oncologist told me there wasn't enough tumor. they sent me thru 6 Mos of chemo. I suffered. have severe issues from it. I had been told all margins were clear (mind u this was nearly a year ago) ..surprise after all that I was told they werent. I got a second opinion. I was told margins were fine (which the original surgeon, oncologist and pathology already stated) but the 2nd opinion wanted a mastectomy for other reasons. I won't get into everything here because it was seriously botched. they new surgeon also ordered the onco score on last year's tumor . it came back chemo "less that one percent benefit." so I did chemo for nothing ...plus more cancer was found. I went the wrong way in the race. I needed the meds.

Anyhow, so now some other things have been found and it might or might not be extremely serious...

I also got a new oncologist who wrote me tamoxifen. radiation oncologist has no issue with being on rads (which I only need because if the new findings, mind you.)

Needless to say...I thought I was nearly done...and now I'm not and not too happy about it. if I wrote everything that was done you'd have ur hand to ur mouth. it's really unbelievable and also very sad. I have young kids who depend on me.
