Early diagnosis of bowel cancer is key to saving lives. It is the UK’s second biggest cancer killer with more than 16,500 deaths from the disease every year — one every 30 minutes (Cancer Research UK, 2022a). Yet, it is treatable and curable if detected early. Almost everyone diagnosed at stage I will survive bowel cancer, but sadly early diagnosis has remained stubbornly low with less than 40% of diagnoses at stages I and II (Cancer Research UK, 2022b).
