Nearly one in two of us will be diagnosed with cancer at some point in our lives. David Nicholas Wilkinson is one of them, twice over. In 2020, a colonoscopy found his bowel to be extremely healthy for a man his age. In 2023, a FIT test came back clear and, like almost everyone who takes one, he assumed that meant the all-clear. In 2024, a second colonoscopy found bowel cancer. Stage 4. He was told his tumour was 5-6 years old. What went wrong? A FIT test looks for blood. Wilkinson’s tumour never bled. Nor do a great many others. 1 IN 2 follows Wilkinson through his own treatment, where he discovers a steep rise in bowel cancer among people far too young to be screened for it, and far too young, it seems, to be believed. Among those who tell him their stories is a bowel surgeon whose own symptoms were dismissed by her oncologist colleagues and in part by herself because she was only 44.
