Hi @Frances54
Diagnosis and all that goes with it is a shock! I assume that there is no special reason for not wishing to have chemo, other than that no-one in their right mind would do it unnecessarily? In which case a test may help (I haven't done it and others may be better placed to advise) but the critical factor is that percentages don't provide the cruncher information. If you knew that with chemo you would fall into the 4% who now won't have a recurrence but would have without chemo, you probably wouldn't hesitate, would you? The problem is we don't know. Chemo is a scary thought, but some people have found it to be less daunting in practice. I was one of the lucky ones with no nausea, no fatigue and no chemo brain during a similar chemo regimen - A/C, then 12 rounds of Taxol normal dose. Yes I did have a couple of side effects, but one at least was compounded by age (I was 67). So far (6 years), so good and absolutely no regrets about doing it, on too of a mastectomy. Best wishes whatever you decide.
