Joy,

Thank you for the information on Markers. Very good info.!

Regarding your question on PET Scans...my PET showed an uptake in what they believe is in my level III ancillary lymph nodes of a 5mm area (will be having surgery to remove it this on 7/13).

I don't know about the 2 cm. rule. I was told that CT scans can only pick up areas of concern that measure 3 cm. or larger.
