TV host Jeremy Clarkson revealed that he is battling cancer during the latest episodes of his hit show "Clarkson's Farm."

In the final two episodes of the Prime Video documentary series' fifth season, the 66-year-old British television personality shared that he had been diagnosed with cancer while speaking to his co-stars Charlie Ireland and Kaleb Cooper, according to the BBC and the Guardian.

"I had a medical, remember, back in May?" Clarkson said, per the Guardian. "I disappeared off the other week and I had a biopsy, and it is cancer, and it's aggressive, but it's really early."

The "Top Gear" star said that he had known about his diagnosis "since May." According to the Guardian, the episodes, which dropped on Wednesday, were filmed last year.

"I promise I'll be fine," Clarkson told Ireland and Cooper.

According to the U.K. outlet The Independent, Clarkson said that he would be undergoing surgery in the coming weeks and would be "slightly out of action."

"If I hadn’t have got myself checked out and they hadn’t caught the problem early, this could well have been my last harvest," Clarkson shared, per the Guardian. "It’s only because they did catch it early, there’s every hope that I’ll be harvesting this farm for many, many years to come."

"But if this is all successful, I'll see you for season six, and if it isn't, I won't," he concluded. "Take care everyone."
