My dad served at Camp Lejeune in the 60s and he had non hodgkin's lymphoma, which is one of the presumptive diseases. He has been in remission for 2-3 years now. Can I file a claim for him now and try to get him service connected? Or does the disease have to be active? Also, if I file a claim today when he is in remission and a while later we find out the disease is active again, would I have to file a new claim or just submit new evidence showing that the disease is active?
Thanks in advance.
