My experience at several CCC is a post treatment scan, all PET/CT, were done 3 months post treatment, and then 6 months after that, but I never made it past that before a recurrence. I read an article that said regular doctor follow-ups, with a palpable and visual exam, were just as effective as scanning, and scheduled scanning was unnecessary. I also read elsewhere, that a PET/CT is like 28% more effective in detecting cancer than a doctors exam is. I did find all my cancers in my lymph nodes myself, confirmed by PET/CT, FNAB, except my last one due to having a pec flap, which is one of the negative aspects of one, and makes recurrences difficult to detect, so I need scans now. I think I had about 14 scans or so.

Good luck with your doctor visit.
