A possible alternative for some
For those who are considered low-medium risk, this might be of interest.
My doctor just ordered a Cologuard collection kit for me. It costs $650 and is covered 100% by Medicare.

It's a non-invasive test that arrives in an 8" cube box, with all the instructions, etc. (A major thing is not to collect on Fri or Sat so as to reduce the return shipping time.)
It avoids a lot of the issues with a colonoscopy: having to do the prep, arrange for a driver, take the day off work or play, deal with anesthesia, etc.
My doctor said she's planning on doing one of these every X years (I forget what she said, 6 or 10 years) until she dies, assuming her results are good.
I have a friend who is scared-to-death of having his colon perforated if he undergoes a colonoscopy, so he is quite interested in the Cologuard test.

Colon cancer is nothing to mess with. My BIL had stage 4 colon cancer. He had chemo, radiation 2 major surgeries, and now wears a [permanent] osotomy bag. Initially, he was returning for follow-up tests (MRI, colonoscopy) every 3 months. Two years later, they found that it metastasized in 2 locations in his lung. He had another surgery to remove those. Soon thereafter, his follow-up testing was increased to every 4 months, then every 6 months. And now, 7 years since his original surgery, he's on a 12-month follow-up testing schedule. He's considered a cancer "success" but not without some loss of quality of life. (Living with the ostomy bag is not easy, it makes airplane travel difficult (as he needs to vacate his system the day before) and he needs to watch what he eats, (as some things give him trouble).)
