Rogers wants to raise awareness of bowel cancer, especially among younger people.
“A lot more young people are getting cancer now,” he said.
“I just want to turn this negative situation into a positive by raising awareness about the symptoms.”
Bowel Cancer UK, external has data showing a 52% rise in cases among adults aged 25-49 since the early 1990s.
Genevieve Edwards, the charity’s chief executive, said: “We’re incredibly grateful to James and Ellie for raising awareness.
“Although the disease is more common in the over-50s, there is a growing body of evidence globally that bowel cancer is increasing in younger people.
“As James’s story shows, bowel cancer is treatable and curable, especially if diagnosed early.”
She said people of any age should contact their GP to ask for a test if they are experiencing symptoms like “bleeding from your bottom, blood in your poo or a change in your pooing habits”.
