Precision highlights role of ChemoFx test, multi-gene predictors for breast cancer

[Rich66]

we can describe genetic information as 'permissive', that is it tells you what you may or may not become. Functional information is 'predictive', it tells you exactly what you are.

Ok..might there be some value in knowing what the current sensitivity is while trying to discern what the cancer might be permitted to do? i.e. the road it's on now and what roads lie ahead??
