oncologists so worried about cost of treatment that they are not giving options to patients

I will be discussing with oncologist on Monday - I have had foundation one testing done by sending a tumour sample to the US a couple of years ago - cost $4,000 - so I will be checking if this is just an Australian version of that or if it looks at more things - I'm just cross that you have to know to ask for this stuff and oncologists don't bring it up.
