@windyshores In fact that was what I head as well from the oncos - that they typically will only do it for adv stage 3 or stage 4 b/c they're expecting mets. For me I'm less than 1 year post diagnosis so its a way for me to monitor that my newly started treatments are actually working as intended, with a goal of getting to that much coveted 10 year anniversary disease free and then many more hopefully after that! 🙂
