Hi Joannie
There seem to be many wise women on here who I suspect would say ask your Surgeon so that you get the correct answer and I think that is really good, sage advice.
That said my understanding (as I asked my surgeon the same thing) is that it is only ONE of several factors they take into account when deciding what is the best treatment for you. They do not rely on any one single factor in isolation but rather evaluation of treatment options is based on a constellation of factors. Ki 67 is, as I understand it (and I am not a doctor), a measure of how how fast the cancer cells are proliferating, lower rates being better. You would have to ask your doctor about what is low and high.
Notably, my KI67 result following my core biopsy was much higher than what it was after my lumpectomy. My understanding is the latter result is more reliable.
Good luck and trust in your team.
