I had a slight upwards change of my tumor from the time of my biopsy until the time of my lumpectomy with 1 lymph node biopsy. ER+ PR +low HER2 -
Because one node was involved it was recommended I was a candidate for radiation. (CA 74, Onco score 13) I had 16 rad sessions and was put on an estrogen blocker 2 weeks prior to the beginning of my radiation. I'm now 6 months past radiation. My ER /PR HER2 number were never run a second time as far as I know. Good idea looking at your measurements again.

@pat9892 I’m not sure I understand the comment about re-running the numbers. My understanding is the ER, PR and HER2 numbers are run on the tumor to determine its makeup. Same with the Ki67 and oncotype. Doing treatments wouldn’t change any of these? If they were rechecked, it would be done off the same tumor tissue that was saved, not a blood test. Are there other numbers that should be rechecked? My oncologist uses the Cea and tha Ca27-29 tumor markers and rechecks these regularly. There are some who don’t recommend them because they aren’t totally accurate (and it has caused some problems with my treatment) but they are blood markers, not actually tumor tissue markers.

@pat9892 what does CA 74 mean? I am not familiar with what CA means. Would you mind explaining it to me?
