There are lots of people who simply trust in the Almighty to ensure they come to no harm. It is quite stunning to observe how many of them come to serious grief. Others take various steps such as preventive measures and going through screening. It is very interesting to note that these steps actually reduce all manner of counts such as incidence of disease, severity when disease occurs and mortality among patients. For example, Just today I saw statistics for Iceland which, since introducing screening for cervical cancer in 1964, the incidence of the disease has fallen by 70% and mortality by 90%. While Iceland and UK are different, nevertheless if you don't want that sort of result, don't complete the self test and start praying more instead - bowel cancer screening follows the very same principles. I have thus far completed three kits at two year intervals.
