trust your onc. My tumor markers stay in the normal range all through my NED in body state, yet with a brain full of tumors. It is a mystery. So, trust your onc and your scans. Deep breathe, too )
My tumor markers stayed with in normal range all through my skin mets recurrence. They are not 100% accurate and for some people they do not work. Once I had surgery they have been normal and yet we knew my cancer was progressing. Hope this help and you can have a nice weekend. Hugs, Sandy
