Dame Deborah James will make her final TV appearance on 'Embarrassing Bodies' - and she's given her "blessing" for the episode to air even if she has passed away.
The 40-year-old podcaster and blogger moved to end-of-life care earlier this month after battling bowel cancer since 2016, and she hopes people will continue to check their poo after she has departed.
She told The Sun newspaper: "I might not live to see the episode air but I hope the message to 'Check your poo' will live on, long after I'm gone.
"It might be embarrassing but it might just save your life. Early diagnosis of things like bowel cancer saves lives.
"So don't live to regret it, and don't risk dying because you're shy.
"I've given my blessing for this episode to run if I'm gone, if it helps save one life it will be worth it."
Deborah's episode is expected to air in June when the show returns after seven years.
The programme's new series will also see former 'Geordie Shore' star Vicky Pattison and singer Lisa Maffia raising awareness of health issues.
Deborah's Bowelbabe Fund has raised more than £6.4 million for Cancer Research UK in less than two weeks after she announced on May 9th that she was stopping treatment.
Deborah - who was instrumental in helping to launch the No Butts campaign, which raises awareness of bowel cancer, on 'Lorraine' - recently revealed she had moved into her parents' house in Woking for the sake of her children Hugo, 14, and Eloise, 12.
She said: "It's kind of where I've always wanted to die, weirdly. I've always had that in mind.
"I think I always knew I didn't want to be at my London home. It doesn't feel right to me."
Deborah was presented with a Damehood by Prince William last week.
