Roger, your post is a common concern among survivors. Getting cancer is one way to force us to face our own mortality. After everything you have been thru its only normal to be afraid. I guess with time you will begin to move past this. Seeing a therapist should be helpful with this. I know how hard it is but for your own good, try to think positively. You are now a cancer survivor so my suggestion would be to focus on living your life instead of dwelling on negative things. It is something beyond your control and to worry about things you can not change is a waste of time and energy. This is why I always advise survivors to go out and to live their lives. Cancer is like a thief, it will steal your time away from you.

Statistics are just numbers. To me they mean nothing. I have beat the odds and I know how lucky I am to still be alive. How many 3 time oral cancer survivors are out there? Not many! If I had paid attention to the numbers and had seen how slim my chances were I could have negatively affected my outcome. I am a firm believer in positive thinking. Of course this is just my idea, I dont think there is scientific proof that positive thinking works. For me it does.

Go out and live your life, dont worry about your odds. If it would come back then it would need to be dealt with. Worrying wont help make you feel better. Especially worrying about something that may never happen. Of course we all like to be prepared for things but worrying about getting sick again is unproductive. It makes you focus on "what if" instead of getting out there and living a good happy life. Everything in life is a choice, hope you choose to move past this and be happy.
