Hughes took to Instagram to announce the news on Tuesday evening.
Posting a picture of the pair of them as children, he wrote: “A sad day. My brother was diagnosed with testicular cancer this lunchtime, in which we pray for a kind prognosis.”
Hughes revealed that his brother Ben had discovered a lump in his testicles the day after Chris appeared on This Morning and urged viewers to check themselves.
“He came into my room at 3am the morning after my testicular examination on tv, clearly struggling to sleep, telling me he’d found a lump and asked me if he’s checking it right.
“To which I told him, ‘Ben, it’s 3am, I’ll look in the morning, but if there’s a lump, go and get it checked tomorrow with the doctor’.
“Today he sent me a message telling me the news, and thanking me for making him aware, else he’d never have known he had cancer.. That literally broke my heart.”
He added: ‘Testicular cancer is a silent killer, men need realise this and check themselves regularly. It takes 10 seconds. Please do it.’
When appearing on This Morning to raise awareness back in November, Hughes allowed himself to be examined live on air by Dr Chris Steele.

He then discussed his own testicular health scare, telling hosts Phillip Schofield and Rochelle Humes: “I was diagnosed with two separate conditions, I had operations but there was no long-term damage.”
“I was around 14 and I noticed like a build up of veins and eventually got it looked at and they referred me to hospitals and I ended up having three operations on my left testicle, and that was more down to safety with infertility, because the veins take oxygen.
“My sperm count was quite low. I have had a hydrocele. I have had four operations on them,” Hughes said.
