I am in the exact same situation and decided to act now. The question certainly isn't settled and Mayo is 2 months into a long term trial to determine whether waiting to see the cancer is as effective as early treatment with radiation and adt as indicated. So when you recur they present this option and ask if you want to postpone treatment. As you, I have idc , cribiform, early recurrence and a doubling time of three to five months. I personally do not feel comfortable waiting and am proceeding immediately with treatment.
