I had the Endopredict test and as I had it at Christmas it took nine days to get the results. My oncologist said it normally took two or three days.
I would suggest having more confidence in the test. Chemo is understood. They know how it works so if they detect something in your cancer sample that indicates chemo wouldn't be useful I'd accept it. And vice versa.
The time will probably come in our lifetime when chemo won't be used anymore. It is a scorched earth, napalm treatment. And what's more, there are many out there who had chemo and their cancer came back anyway.
These personal genomic tests are the beginning of the future of individualised medicine. I'm not a medico, but I know that in Australia we get the breast cancer treatment in the world (we have the best survival rates along with Finland). Go with confidence and trust your medical team.
You won't know either way if you don't do the test, and no one will make you do anything you don't want to. Your body, your life. However if the test indicates that chemo would be of no benefit I doubt you'd find an oncologist that would prescribe it in the face of that.
So take a beat, go for a walk, talk it over with a trusted friend or partner, sleep on it, and see what your gut tells you.
Whatever happens, we're here for you. K xox
