Annals of Surgery article on increased risk of colorectal cancers?

I was wondering if anyone had had a chance yet to talk to their surgeon about the study published in the March issue of Annals of Surgery on the substantial increase in risk for colorectal cancers among bariatric surgery patients?  It seems like the study offers more questions than answers, but it's something to be aware of, and is probably a reminder we should all be vigilant about screenings.  Melting Mama's site had a long post on the study.

I wonder if the risk is higher for all bariatric surgeries, or just for/more for RNY, which reroutes the system?

I wondered that myself, but at least from the abstract I was able to read, it looks like they don't have a theory on the cause, just a correlation of higher risk.  If I recall correctly, one possibility mentioned was that it could have been the substantial lost weight, rather than the surgery, in which case it would apply to non-ops as well.   My guess is that we won't know more until additional studies are done, but I plan to put it on my list of things to mention to my surgeon next time I'm in.  I'm not worried, but I think it's always helpful to be aware of potential side-effects so we can be proactive with screenings, etc.

It's just one study. In science, a result has to be repeatable before it counts. And in statistics, correlation is not causation. To me, all the study says is: this is interesting and needs further study. Which is pretty much what the study authors said.
