Louis Walsh was diagnosed with a rare form of cancer
Louis Walsh has revealed that doctors initially ‘couldn’t find anything’ before he was diagnosed with a rare form of cancer. The TV star and music manager was diagnosed with Waldenström macroglobulinemia in 2024.
The former X Factor star. 74, publicly shared his diagnosis during an appearance on Celebrity Big Brother, telling Love Island star Ekin-Su and Levi Roots that during lockdown, he was “sick” and nobody knew he had been secretly battling cancer. He later underwent treatment in Dublin.
Waldenström macroglobulinemia is a rare, slow-growing type of non-Hodgkin lymphoma that affects white blood cells in the bone marrow and lymphatic tissues. During an appearance on The Big Interview, Louis shared that medics initially couldn’t find the disease in his body.

“I had a cancer called Waldenström,” he said. Louis went on to add: “And I didn’t know I had it. And at the end of the X Factor series, I was just feeling very weak, and I went to the doctors.
“They couldn’t find anything. And then, one of the doctors called me back, and he said, ‘I think it’s this rare one’ — it would be rare for me — ‘called Waldenström.’ But I’m told, if you’re going to get a cancer, this is the one to get!”
When asked if he underwent any treatment, he disclosed: “I had chemo for a week. It wasn’t bad. It wasn’t bad at all – but I couldn’t sleep at night time, so the nurses gave me loads of tea. They were so nice, and I was smiling.”
Louis was later asked whether he was in remission and “100 per cent clear of cancer,” to which he responded: “I think so, oh totally, yeah.” Reflecting on his private health battle, he said in the Big Brother house: “I didn’t even know I had it until I went to the hospital. They checked me, and then they found it.”
He said that his diagnosis affected him mentally, saying: “It’s just up here; even when I go past a hospital, I almost get sick. It’s all gone, I’m fine. It was just the shock of being sick, and that word – nobody wants that word.
“I have it blocked out, a reality check. You see so many people sick, and it’s terrible. In my world, it was all about pop music and all that. I didn’t think of anybody getting sick or anything like that. And that was like, wow, reality check – you’re in the real world.”
During his time on the show, Louis was often seen sleeping. A source said at the time: “Louis is in remission currently but you can see how frail he is and that he has lost a lot of weight. It’s also the reason why he’s sleeping so much; it all took a lot out of him.
“The whole experience was the main driver behind signing up for the show. He’d been really ill and just wanted to enjoy life again and thought, ‘What the hell!'”
The Big Interview: Louis Walsh airs Tuesday, October 27, at 9pm on Virgin Media PLAY and Virgin Media One.
