Hello Jamie; Please don't worry in advance. Suspicious cells are just that until they are positively identified. I had some "suspicious cells" that turned out to be scar tissue.
That being said, I did have a recurrance fairly soon after my rad Tx which necessitated an extended neck dissection two months ago. My prognosis is poor (the docs say) but until someone decides to pay me for time spent worrying, I think I'll just enjoy this particular time of being cancer free, and deal with the other stuff if and when it comes along.
I wish you peace and calmness as you continue to be such a wonderful caring supporter to your Mom. She is truly blessed to have you.
All the best,
Fran
