Let me start off with how I understand how confusing it can be to be in that situation. All my results too are normal however some markers I have been told do not indicate or are reliable in the presence of cancer. In my case Cholangiocarcinoma which was diagnosed in Dec showed no true signs other than PET/CT and biopsy. I encourage you to speak openly with your Oncologist to clarify your condition and scans to better help you make a decision you feel comfortable with. I encourage second opinions as well they will also make you more at ease with you decisions.
