I've just noticed this thread - I'm not a flyer but I can speak for the long term surviveability rates of a Hodgkins Lymphoma - I was diagnosed at the age of 23 in 1992 and have been in remission sicne August of that year (approaching 16 years).
Since the Chemo/Radiotherapy (which lasted around 6 months), I've had two further children and have managed to hold down a pretty challenging career in IT Optimisation/Transformation.
My Oncologist always said this one was the best one to get and that 5-10 years down the line there was as little chance of a relapse as there would be of someone else getting it the first time around.
