VH, I'm not sure where you're located. If you're on the west side of the pond, I might suggest some places to go for another opinion. Not much help for places in Europe, though.
I suspect that the recommended treatment might depend somewhat on the specific cell type and location of the tumor. (Endo- versus ecto- cervical, for instance.)
I think what your docs are saying is that these nodes may well have been positive for a while, and though it is unlikely that you can eradicate every last cell there, there may well be an opportunity for long term control of the nodes should they progress. Meanwhile you have to weight the risk of the treatment against the benefit.
PM me with more detail if you wish. Good luck to both of you.
