Piers Morgan has revealed he was saved from cancer by an observant viewer who spotted something alarming about his appearance on TV.
The Good Morning Britain host was warned by a melanoma expert that he had a concerning blemish on his chest, which he rushed to get checked out.
The 52-year-old's life may have been saved by Gillian Nuttall, founder of Melanoma UK, who contacted him after seeing him in the ITV Serial Killer documentary.
Nuttall said the mark, visible just above his open-neck shirt caught her eye and "really bothered" her, so she got in touch after viewing the episode in November.
She emailed him to say: "Piers, at the risk of sounding like a lunatic, I'm just watching your programme and there's a blemish on your chest. Have you had it checked?"
The father-of-three, who is married to journalist Celia Walden, 41, said: "This week, a top dermatologist took one look and immediately cut it out.
"Much further delay, he informed me, and it might well have turned cancerous. Give that lady a gold star."
Expressing his gratitude to the eagle-eyed Nuttall, he said: "Thanks, Gillian. Oh the irony of a serial killer inadvertently helping to save my life. Merry Christmas!"
Manchester native Nuttall wrote on social media: "He was interviewing a serial killer and I watched it. He had an open neck shirt on and it caught my eye. "I stopped the TV and looked closely. It really bothered me so as I'd got his email, just thought 'quick shove in the right direction won't harm'."
She joked: "I was right. I haven't got a Piers Morgan fetish, honestly!"
Nuttall founded Melanoma UK in 2007, which supports patients of the most deadly form of skin cancer, usually detected when a mole appears.
Piers talked to a series of notorious killers in America for the ITV1 documentary Serial Killers.
He admitted he gets "very involved" in the cases, after spending a week studying the killer and meeting their families.
"You do get very involved with these crime ones, you spend a week immersed in it and it's chilling," he told the Mirror.
"You go into the scene of where it happened, and you engage with families. It consumes you."
He risked the wrath of convicted killer Mark Riebe, 56, on the show after taunting him about the dozen women he claimed to have murdered before later recanting his confessions.
Riebe is serving life in a Florida prison for the 1988 murder of pregnant mother Donna Callahan, but just one year into his sentence he began to share gruesome details of multiple other unsolved murders.
He later claimed he had been tricked by the US government into the confessions and adamantly maintains his innocence.
