I failed to include answers to your questions.
Message Boards noted it COULD be years before Follicular Lymphoma needed treatment. However it may have been in your body for years before you found it too.
The Onc said since it was probably Stage 2, possibly Stage 3, Radiation would not be recommended since multiple areas would have to be radiated, and no one knows where the little critters will strike next. Radiation is good for a limited area in the body.
The minimalistic Treatment is R (Rituximab) over multiple weeks. Multiple regimens can be used as long as R works.
That's why he recommended R-CVP. These drugs are the same as R-CHOP, with the addition of a very nasty drug which affects the heart in undesirable ways. Each drug "kills" cancer cells at different stages of cell growth, which is why he recommended the multiple treatment (R-CVP) instead of just R by itself.
He said that "generally" you could only get these drugs once, and then have to move on to other regimens of combinations of drugs.
So that's why I decided to Watch & Wait as long as I can, because of the fear (real or perceived) that by selecting these other Regimens, I would "Use Up" options I might need later.
As I noted before if the Lymph Nodes have grown larger than I expect, I will have to choose a regimen of one (R) or more Drugs.
I hope all is well with you.
