Alex, good luck with your decision making. Process, it sounds like you've got the right mindset, and will go about
this in a methodical way.
I would encourage you, when considering AS, to not discount the importance of the psychological aspect. It's important, and I sometimes feel it is given short adrift. If you are the type that will always worry if you choose to not trailhead but do AS, you may need to think about
it harder. I say that only because of your comment "I want reasonable peace of mind that we have caught this in time".
With that said, remember that it's quite possible that your cancer is so indolent that it might NEVERTHELESS be too late, and AS would work fine for you. (That's what makes this decision making process "so much fun"
My story is similar to Halbert, I had a G6 biopsy that was upgraded to G7(3+4) on surgical pathology. I was lucky in that inhave no side effects. However, you won't know if that will be the case for you. Age doesn't necessarily dictate the outcome on side effects, although I imagine the younger you are the more of an edge you may have. But no guarantees.
So consider that carefully as well.
Best of luck, and keep us posted
