Heck yes, get checked. You don't want to become a statistic.
Kaiser-Permanente (pretty much a CA only medical foundation) uses the doo-doo test as a screening. It's free, so there's no excuse for not sending in your sample. If the stoolie shows something, then they do further testing, I assume the scope job.
It's a pretty easy, once a year kind of thing. I suppose the hard part for some would be reaching into the bowl to fish for the sample.
