Hello Donna, this is still a time of uncertainty and I do know that this is scary.
I would be somewhat reassured by the Fellow and his opinion on the Lymph nodes. I guess the CT is to exclude any new tumour causing spread to the Lymphs. I also think that it is good news that he did not find/feel a mass.
So, " Don't borrow sorrow from tomorrow ".
Take one day at a time and I will keep you in my thoughts and prayers.
