Jeremy Clarkson is fortunate that his prostate cancer has been caught early because the 'vast majority' of 'localised' cases can now be cured, doctors said today.

The broadcaster revealed he had been diagnosed with 'aggressive' cancer in the final two episodes of the fifth season of Clarkson's Farm, which were released overnight.

The episodes saw the visibly emotional 66-year-old former Top Gear and Grand Tour host relay the news to his shaken co-stars Charlie Ireland and Kaleb Cooper, who run his Diddly Squat Farm in the Cotswolds with him.

Clarkson revealed on the Amazon Prime Video series, filmed from late 2024 to September 2025, how he had been diagnosed in May last year, telling farmhand Cooper that 10 per cent of his prostate 'where the cancer is' is 'dead'.

He began treatment and underwent an operation in August, before being rushed back to hospital in dramatic scenes which marked the end of the series.

Consultant clinical oncologist Professor Joe O'Sullivan, professor of radiation oncology at Queen's University Belfast said it was a positive that the cancer had been diagnosed early.

He told the Daily Mail: 'As with most cancers, the earlier you catch prostate cancer the better. As time goes on, the more likely it is to spread and that is particularly true of aggressive cancers, like Clarkson's.

'Increasingly, we are getting better at treating localised prostate cancer - irrespective of how 'aggressive' it is. We can now cure the vast majority of these with radiation or surgery.

'But usually when cancer spreads, it becomes incurable. Being overweight, and having a larger waistline, is a risk factor for prostate cancer - there's no doubt about it at all.

'Leading a generally healthy lifestyle, so cutting back on saturated fat and alcohol, eating well and exercising - as well as getting high cholesterol down - will reduce the risk of prostate cancer. We know rates of the disease are higher where there is more obesity. These are well-established facts.'

The final episode concluded with the presenter telling viewers: 'If this is all successful I'll see you for season six and if it isn't I won't. Take care everyone.'

Clarkson was talking about plans for the upcoming harvest with Kaleb and Charlie when the broadcaster dropped the bombshell news on them.

After establishing the farm's crops will be ready for harvest at the end of July, Clarkson exhales and says: 'F***'.

As Kaleb asks if he is 'going away', Clarkson leans back into his chair and, while struggling to keep his composure, tells the shell-shocked pair: 'Yep. I've got cancer.'

A disbelieving Kaleb quickly says back: 'No, you haven't. Where?' to which Clarkson says: 'Where it is of no concern of anybody. I've known since May.'

The father-of-three goes on to reveal he has been diagnosed with an 'aggressive' form of cancer and will have to take time off during the harvest.

While telling Kaleb and Charlie the news, Clarkson says: 'I had a medical, you remember back in May. I disappeared off the other week and I had a biopsy and it is cancer and it's aggressive, but it's really early so the treatment will be, you know. 

'I was praying we could get the harvest done and then I could go and get some treatment but it's going to be slap bang in the middle.'

Meanwhile, a tearful Kaleb - who is seen wiping his eyes during the conversation - throws his support behind him, saying: 'Look after yourself, you go and do… if you need anything you just ring me.'

Clarkson reveals that treatment includes an operation 'slap bang in the middle' of harvest time, and that as a result his body will be 'out of action for a little while', adding that he 'wasn't thrilled' at the prospect.

Charlie tells him: 'I just wish you a very, very speedy recovery.' 

He then quickly turns back to harvest arrangements, telling the pair that his girlfriend, Lisa Hogan, will need to take on some of his duties. 

The farm faced a desperate race to harvest its barley and wheat before his treatment, with matters complicated by Kaleb's wife being due to give birth to the couple's third child. 

While carrying out the harvest, Clarkson hails early detection and intervention as the 'only reason there is any hope'.

'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. It's only because they did catch it early there's any hope. I'll be harvesting this farm for many, many years to come.'

In a later scene, the presenter says he was given just six days notice ahead of his operation, which took place at a hospital in London on August 4. 

In scenes filmed the day before, Clarkson looks nervous as he and Lisa leave the farm. 'I'll see you on the flip side,' he tells Kaleb.

In what were originally the final scenes of the series, Clarkson tells Lisa, Kaleb, Charlie and Gerald: 'So we started the year and I had coronary heart disease and ended it with me with cancer.'

He continues: 'We can dwell as much as we like on all the bad things that have happened on the farm but I think it is better now at the end of the year to focus on things that have happened that are good.'

When asked by Kaleb when they will know if the treatments have worked on the cancer, he replies: 'I don't know, I've got a blood test today, there'll be a blood test and then we'll know.

'Not for another few weeks. Come on cheer up, it probably did work.'

Clarkson reveals that filming had wrapped after the fireside chat, but matters changed after he was rushed back to hospital. The final episode cuts to an ambulance with blue lights, and then the presenter in a hospital bed, where he reveals things haven't gone completely to plan.

He says: 'Some of the treatment has gone awry, let's say, I'm going to be here for a little while. I'm nil by mouth, I don't know what's going to happen.

'What I wanted to say was if this is all successful I'll see you for season six and if it isn't I won't. Take care everyone.'

Clarkson had hinted beforehand that not all was well, and in a press release ahead of the first episodes of the fifth season, Prime Video ominously warned: 'In the climactic episodes, things turn dark as bad luck strikes from every direction, causing massive upset and tension in every way possible.'

Taking to Instagram ahead of the release of the final episodes overnight, Clarkson revealed in an openly emotional video that they are a 'really, really difficult watch.'

After sharing that his lager and cider brand Hawkstone would have an advert ahead of England's first World Cup match tonight, he continued: 'Sombre news: Clarkson's farm. 

'Ordinarily we try to keep the show bucolic and charming and cheerful, but the final two episodes which drop in the middle of the night tonight are, they're none of those things really, they're a difficult watch.'

Becoming visibly emotional, he added: 'They're really, really difficult.' 

Just two days ago Jeremy was showing off his trademark sense of humour, plugging his beer brand while celebrating British drivers coming first, second and third in the Barcelona Grand Prix.

Clarkson has kept busy since the show was filmed, with production currently underway for the new series of Who Wants to be a Millionaire, which he hosts, while a sixth season of Clarkson's Farm has been ordered by Prime Video.

Production of the next series is expected to pause to allow Clarkson time to recover. 

Clarkson's co-star Gerald Cooper was also treated for prostate cancer and underwent surgery in 2023 – before the show's producers confirmed in 2024 he was cancer-free. 

Clarkson's diagnosis comes after a difficult couple of years for the broadcaster, who was rushed to hospital in 2024 after suffering from chest pains.

While on the ward, doctors discovered one of his arteries was 'completely blocked' with the presenter later saying he had been 'days from death'. 

Fortunately surgeons were able to resolve the issue by inserting a stent - a tiny, expandable mesh tube that is placed in narrow or blocked coronary arteries to restore and aid the flow of blood.

When he returned to work after that health scare in one of the early episodes of the fifth series, Clarkson told Kaleb: 'I'm back and not dead. The grim reaper will have to wait. It was f***ing close, though.'

The former Top Gear host revealed he first felt unwell in 2024 following a swim in the Indian Ocean while on holiday.

He explained that 'it wasn't far, maybe the length of two swimming pools. But when I finally reached the beach, there was more water in my lungs than there is in Lake Superior, and I was mostly dead.'

Clarkson returned to Britain and a 'sudden deterioration began to gather pace' with him feeling 'clammy', 'tightness in my chest', and 'pins and needles in my left arm.'

This led him to being admitted to hospital where a heart attack was ruled out after he had an electrocardiogram (ECG), blood tests and X-rays.

Following the life-saving surgery, he was warned by doctors that he must make major changes to his lifestyle.

Since it was first released on Amazon Prime in 2021, Clarkson's Farm has become a huge hit and gone on to have four successful series.
