BarbaraRoberts,
Hi! I believe it depends on what type of cancer you had. I have/had DLBCL and was told by my oncologist at the Cleveland Clinic that if I get to five yrs she can tell me I'm cured. That I have as much chance of getting it again as anyone else in the U.S. I have been in remission now for 3 1/2years. Congratulations on being in remission for so long!! I hope I can say that too someday!! Kelly

Ich wünsche allen gute, ich habe Mantelzell Lymphome habe sechs Chemos hinter mir und die erste Immuntherapie weg.Ich habe etwas Sehprobleme und hoffe die gehen wieder weg .Meine letzte Chemo war vor 8 Wochen.

I am also in remission from NHL, though it's only been 1,5 years. What you're saying about being in remission for so long is immensely encouraging for "newbies" like me.
As for your question: Doctors here in Germany are saying that they can't cure my type of NHL (follicular) but that I may live with it to a ripe old age - I'm 59 now. So for me I'd say that I'll be in remission until the relapse happens, which may be in 2 months or never.
