Yes the suggestion that chemo might be helpful starts at Oncotype score 16. I didn't want to emphasize that! If your estrogen and progesterone scores are high, that is good news for your possible response to meds and consequent reduction in risk. But that also leaves me wondering why your Oncotype was 15. And yours was grade 1. I called the company and talked to someone there who explained my score (low despite high grade and LVI). I don't know if Exact Sciences does that anymore: at the time it was Genomic Health. But worth a try.

Maybe you will feel better getting a second opinion. I got 4 🙂

I had an Oncotype done on biopsy tissue. They should be able to do that. Ridiculous.

If your cancer is on the right side, it might be better than on the left for radiation due to the heart being on the left. That is what I was told.
