So here - inevitably - comes his new chatty podcast.
Across the series Jon will be joined by the comedians Stephen Fry, Mark Steel, Richard Herring, Matt Forde, and Eric Idle, actors Colin McFarlane and Ben Richards, rock star and The Alarm frontman Mike Peters, and journalists Jeremy Langmead, Nick Owen, and Jeremy Bowen. Jon and his guests will demystify all things cancer in raw, honest, difficult, often absurd and - yes - funny detail, from fingers up the bum to blood tests via biopsies, surgery, catheters, stomas, feeding tubes, penis pumps (no, really) and incontinence pads.
Jon wants to stop the stigma and embarrassment associated with these issues (and by "issues", we mean "body parts and what happens to them"), to raise awareness and encourage listeners to 'get checked' as Jon aims to remove the fear from the whole diagnosis and treatment process in an accessible, honest and entertaining way.
Throughout the series, we will also be encouraging listeners to get involved and share their own experiences, whether it's something they have been through themselves or are supporting someone with cancer.
Jon Holmes Says The C-Word aims to humanise what is often a completely de-humanising process, because, honestly, the cancer road is paved with often hilarious unexpected moments - and Jon maintains that retaining a sense of humour is all important.
As Jon says: "If there had been a podcast like this when I was diagnosed - one full of other people's stories, advice and light moments to illuminate the darkness of the whole sorry process I'd have lapped it up. But there wasn't, so I spoke to Radio 4, and now there is."
In Jon Holmes Says The C-Word, Jon will be wearing his heart - and, quite frankly, all of his body parts - on his sleeve.</p>
