who is in charge of your case?
I think you need someone to be in charge and for you to listen to them.
It WAS straightforward and now isnt: lots more data than 20y ago allows doctors to judge: do you have it? how far has it gone? and does treatment lengthen life?
They thought they knew the answers to all this, but whether early treatment works is now in doubt. (That is, patients who would never go anywhere were subjected to 'over-treatment')
get hold of your doctor in charge and ask
to kick off
