Hi Elizabeth - thanks for your great suggestions on exercise and thanks for sharing your personal point of view about cancer screening. Bowel cancer is our second biggest cancer killer yet 90% of cases can be cured if found early. The reason we promote screening for bowel cancer is because there are often no symptoms until the cancer has advanced, when chance of survival is greatly reduced. We agree people need to make an informed choice about what’s best for them re: screening, we also need to make sure they are aware of the options for early detection and finding cancer at a stage that requires minimum treatment for the best outcome.
