Hi Ron,
I have a "bowel cancer" gene and, even though I had my colon and half my rectum removed in my mid-twenties to prevent cancer, I was diagnosed in 2000 (after being checked every 6 months). I had stage 3 and since found out had 50% chance of survival and up to 5 years - I am still here. Since then I have had 3 more bowel ops, ileostomy in 2000 after chemo and radiotherapy, duodenum removed in 2001 due to polyps (due to gene) and then 3 years ago the next section.
In 2006 my oncologist told me that in 20 years of practice he had only once had someone have their cancer recur after 5 post cancer years. So, the chance of cancer returning after 10 years is very remote.
With all the bowel ops that I have had, my digestion leaves a bit to be desired. After one of my regular gastroscopies (every 6 months) I was put on Nexium - wonderful for indigestion, etc., but then I had the "great" luck of getting an extremely rare side effect of kidney damage and am now at stage 4 kidney failure with about 4 years at the most before the next step.
Survival is not an easy thing, but I always try to remember the alternative, death and then things look a bit better. Sorry to read about your marriage, my brother (no longer here) also had his wife leave him due to his illness. Life can be very unfair.
Good luck with your precarious health,
craftyone
