Unintentionally <LOL> I think we would all like to 'forget' to have these ;P
My GI does them every two years if all is 'well' and otherwise whenever he needs to see whats going - which has been 3 this past year with another scheduled for next wednesday :(
He tells me 2 yearly is good because even if symptoms are OK the disease may still be running rampant so these colonscopys help determine effectiveness of meds, progress of disease plus a bonus cancer screening.
Be well :)
