Jeremy Clarkson stunned fans after revealing he has been diagnosed with cancer during the latest episode of his Prime Video hit Clarkson’s Farm.

The 66-year-old TV host broke the news to his co-stars Kaleb Cooper and Charlie Ireland in an emotional moment on the show, telling them he had quietly gone for a biopsy after disappearing for a short time.

“I disappeared off the other week and I had a biopsy, and it is cancer, and it’s aggressive, but it’s really early,” Clarkson said in the episode, according to the BBC.

The former Grand Tour star said he had known about the diagnosis “since May,” though the episode was reportedly filmed sometime between 2024 and 2025.

Clarkson tried to reassure Cooper and Ireland as he shared the frightening update.

“I promise I’ll be fine,” he told them.

The outspoken British TV personality did not reveal the exact type of cancer, but later told viewers he underwent surgery to remove part of his prostate.

“The prostate, 10% of it’s dead,” Clarkson said in the episode, according to The Independent. “The 10% where the cancer is.”

The episode later showed Clarkson lying in a hospital bed after the procedure, where he admitted the situation was still uncertain.

“I’m going to be here for a little while,” he said. “I don’t know what’s going to happen.”

In classic Clarkson fashion, he even managed to crack a dark joke about his future on the show.

“What I wanted to say was if this is all successful, I’ll see you in season six, and if it isn’t, I won’t,” he joked. “Take care, everyone.”

The shocking health reveal came after Clarkson warned fans that the final two episodes of the season would be unusually difficult to watch.

In an Instagram Reel posted Tuesday, June 16, Clarkson said the show normally tries to stay “bucolic and charming and cheerful,” but admitted the final episodes were “none of those things.”

“They’re a difficult watch,” he said.

Clarkson has previously spoken openly about the importance of prostate checks. In a 2025 column for The Sunday Times, he wrote that he had regular prostate exams after watching too many friends suffer from prostate cancer.

“I’ve had too many friends go down with prostate cancer,” he wrote, adding that early checks could help people get “on top of the situation early.”

Clarkson’s cancer diagnosis comes less than two years after he underwent a heart procedure in October 2024.

At the time, he revealed that one of the arteries feeding blood to his heart was completely blocked, while another was also becoming dangerously restricted.

Now, the beloved but controversial TV host is facing another major health battle — and fans are hoping Clarkson’s trademark grit and humor will carry him through.
