I totally agree - ask for a scan- I understand your nervousness. I'm 7 mos out of radiation today - 9 mos out of surgery... Sometimes it's hard not to think about recurrence - but congrats on being 4 years out. That's awesome. Hopefully your fears are rooted in nervousness about the 5 yr mark and you have no further symptoms!!! You've been through a lot. Recurrence at 5 years is very rare. Hugs and try not to freak. We're here if you need it...
