I was lucky in that the cancer was caught early as a stage 1A, 8 mm tumor (including clean margins)qp. I had a lumpectomy and sentinel lymph node biopsy that was negative for cancer cells.

The OncotypeDX yielded a very low risk of recurrence so no chemo was recommended by my oncologists. I declined site-only radiation. Tried aromatase inhibitors but had side effects and other concerns about them so discontinued them. I'm older so that made quality of life more important than my 5.5% risk of recurrence within 9 years.

It was a judgment call that the OncotypeDX helped me make. Absent the clean sentinel lymph node and OncotypeDX low-recurrence risk result, I wouldn't have had the data to help me decide. Knowledge is power, good data is one source of it.
