Sorry to hear that you have a recurrence. The question that I ask is why does it recur at the site so often ,especiallly in the first 18 mos. I do know that cancer is hard to detect in fatty tissue ,particularly at the base of the flange that connects the colon to the body. Perhaps some docs are a little obsessed with saving tissue and don't give them selves enough clear margins on either side of the ca(I would be happy to take about a foot either side). The other thing that worries me is that when a gastrenterologists finds a ca during a scope, how thoroughly do they check the rest of the colon?. I haven't heard anything to suggest that ca in younger patients is harder to treat. I have heard that ca in younger people is more likely to be genetic rather than as an exposure to carcenogens. Another oncologist suggested that in his opinion the more aggressive the ca the better it responds to chemo. I was stage 3 ,6/13 nodes bad. I had 5FU/leucovorin,till it nearly killed me ,then finished off on 5Fu levamisole(an old old regime) for 48 sessions ,and have been clear for over 8 years,.Good luck with the treatment ,may this be the last you see of ca,best wishes Ron.
