| > I'd posit that the one in 455 people who would die without a colonoscopy would disagree that colonoscopy isn't worth "all the money, time, effort and pain we spend on it." Your post is a fantastic illustration of how and why we can't rely on "consensus" to determine fact. People routinely fall in love with narratives based on what they "know", and refuse to accept new data that challenges their narratives. For literally anything we do, some people will die afterward. You could set up a study where you punch people in the shoulder at random, and follow them to see if getting punched implies a survival benefit. Eventually, everyone in both groups will die -- we'd expect about the same number in each group at any given time, because punching people in the shoulder probably doesn't affect lifespan. But still, people will die after getting punched! Here we have a large, randomized study where approximately the same number of people died with colon cancer after getting colonoscopy as did without the screening. The screening had ~no effect on outcome. Also, you've misunderstood: the 455 people is not the number of people who would die with colon cancer -- it's the number of perfectly healthy people you'd need to screen to prevent one case. > I would suggest that you ask my uncle about it, as he didn't have a colonoscopy and was eventually diagnosed with stage IV colorectal cancer. While I'm sorry for your loss, the data from this RCT suggests that colonoscopy on perfectly healthy people confers little to no survival benefit, and trumps any anecdote. |
No. I haven't. If we don't do any colonoscopies, that 1 in 455 who develops colorectal cancer will die (as my uncle did) if the cancer isn't diagnosed early enough.
Don't want to go through the "trouble" of a colonoscopy after 50 years of age? Then don't. If so, I hope that you or anyone you love isn't that 456th person.
Yes, Anecdotes aren't data. However, that 1 in 455 is a statistic and what are statistics? Data based on aggregations of anecdotes.
I mentioned my uncle not because I want to pull your heartstrings. Rather, it's because while it's a simple thing to look at data and statistics, it's easy to forget that such data (at least in this case) breaks down in to anecdotes just like that one -- e.g., dead and/or very sick people -- who wouldn't be sick or dead with appropriate screenings.
If you don't care that some people will die without colonoscopies, that's your prerogative. I hope that attitude doesn't keep you or those you love from identifying potential colorectal cancer before it's too late.
That you don't care about others getting sick and dying[0] from the fourth leading cause of cancer deaths in the US, says something. Not sure what though and I won't speculate.
I'm sure that the your full-throated support for not doing colonoscopies is cold comfort to the (~36-56/100,000 Americans) ~118,000-185,000 actual, real people who develop colorectal cancer per year.
I'll say it one more time -- there are real people represented in that data. People who suffer and die every day. And if we did fewer colonoscopies, more of those people would, in fact, die, because their cancer wasn't diagnosed at all/soon enough. And so I have to put on my Quincy, M.E.[1] mask and ask: People are dying, doesn't anyone care? Is it correct to say that you don't care, or am I missing something?
It would be easy for me to just wish colorectal cancer on you and then ignore you, but I don't want you to get colorectal cancer (or cancer of any kind for that matter). Dying of cancer is a slow, agonizing, incredibly painful way to die and should be avoided as much as possible.
If you have a family history of colorectal cancer, please, please start having colonoscopies every two-five years starting at age 45.
If you don't, please do so every five years or so starting at age 50.
Or not. It's your life and (eventually) your funeral. That's up to you.
