I believe scientists are moving forward (if not at the pace we want) with more personalized solutions to cancer care. Here is one example for breast cancer using ultra deep tumor sequencing:

I imagine after finding out what drugs are suitable, one approach that could be used is to give one dose and remove the tumor as described in this vid:

This is really n of one testing! If there is more than one tumor, each tumor would have to be sequenced, I suppose.
