I would be thankful that his onc wants to keep a close eye on him. My husband's cancer recurrence was at the 3 year mark and I believe if he had been monitored more closely he might be here now. By the time, he was diagnosed the second time, he was stage IV . He was getting chest xrays only , at the point of diagnosis and his tumor didn't show on the xrays. There has to be a happy medium, but keeping an eye on things is a really good idea.
