The 33-year-old told fans that he was ‘worried’ during his 5 days off from tour after finding the lump.
He wrote on his Facebook page: “My brain: ‘Erm,’ checking through diary ‘not loads, 4 or 5 days off now.’”
“My body: ‘Oh good’… My brain: ‘Why do you ask?”
He continued: “My body: 'Oh, I’m just thinking of f***ing him right up with a bit of the flu, a frozen shoulder, back ache -and a swollen ankle...oh and schedule an appointment in at the doctors cause I’ve just developed a lump on his left testicle so he can spend the rest of his break either ill or worried.’ Cheers body!”
He later posted: “Thanks for some of your concern about my late night post about not being well. A little lump on my favourite testicle, have booked in a doctors appointment tomorrow for a check, I’m sure it’s nowt but it’s good to talk about these things.”
Jason then urged fans to check themselves for signs and symptoms of cancer before sharing a link to an NHS website.
Do you think Jason is right to be so open about his health worries?
