Contradiction?

This is the first year since my diagnosis that I've had 12 months between check-ups (though the nurse wanted to discharge me, the consultant refused to let go).  So, I'm now past the 6 month stage where, last year, I would just have had another check-up. While I'm delighted not to have to go through that again until January, I find that I'm feeling even more worried than usual about the slightest twinge, tiredness or general malaise. This does seem to be a contradiction to my pleasure at being hospital-free for a bit longer!

Of course, as soon as I don't have to go to the hospital, I'm noticing increasing numbers of newspaper articles about cancer, hearing discussions about the likelihood of cancer recurrence, etc., etc. 

Maybe I just need something to worry about, but I'm beginning to understand why people who've had cancer are often more concerned about their health than the facts appear to indicate they need be. Another example of needing to experience something to understand its effects, it seems.
