Kerri,
I did have rad & chemo, with one node, but it had extracapsular extension, so don't know how comparable we are.
I have not looked at the NCCN guidelines recently but you could sure see what they say for your particular "brand".

At any rate, I did have a PET scan but at a different institution from where I had my treatment which was MDA in Houston. It does not seem like MDA does much with PET scans, at least for me. They do CT scans, with contrast, of course. I have had 4, every 3 months. Some places do not do scans as a routine check-up at all. I get to drop back to 4 months now, with CT scans every time.

The PET scan is more involved, more radiation and more cost of course. I'm going to let someone who has those respond to you on that count. PET scans register "activity", glucose uptake I think is how they put it, so it looks at something a little different. After surgery you could have had some "hot spots" because of the inflammation.

As to what they would use I guess you'd have to ask. I would think they might have mentioned if they were going to do a PET scan though.

Probably not too helpful to you--good that you are getting near the year mark!
Best,
Anne
