Military Helicopters: Blood Cancers

Jayne Kirkham Excerpts

Tuesday 8th July 2025 Westminster Hall

[Jayne Kirkham (Truro and Falmouth) (Lab/Co-op)]

I beg to move,

That this House has considered military helicopters and blood cancers.

It is a pleasure to serve under your chairmanship, Sir Jeremy. I am here because of someone who joined the Royal Navy Fleet Air Arm at the age of 19 because he had always wanted to fly. He always had the vitality to attack life and live it fully. He flew everything from Hawks to helicopters, and was a talented and committed pilot. By the time I met him, he was teaching new recruits to fly at RAF Cranwell, and was Navy snowboarding champion. In 2005, he went to Cornwall and was stationed at Culdrose, where he flew search and rescue on the old Sea Kings. I represent Truro and Falmouth. Cornwall is rich in forces personnel and veterans. Five and a half per cent of people in Truro and Falmouth have served, which is a much higher percentage than the national average of 3.8%. In Truro and Falmouth, 4,160 houses—more than 10%—have at least one veteran living in them.

He was living in Dorset when he suffered strange symptoms of blood clots in his lungs and legs in the spring of 2022. It took some time and persistence, but he was diagnosed with multiple myeloma, a rare blood cancer that affects only 5,000 people a year in the UK and is most common in men over the age of 85. He was lucky to have some pioneering treatment in Dorset and later at the Royal Marsden hospital, and he was able to trial drugs that were not yet available in the UK. Treatment is developing for blood cancers all the time, and it is important that people in the UK have access to new treatments. The cancer, however, returned, and he died a year after diagnosis, not long after his 54th birthday. His was not an isolated case. Last Tuesday, in the Welsh Senedd, Julie Morgan led a debate very like this one about RAF winchman Zach Stubbings. Zach died from multiple myeloma at the age of 46, after working many hours on Sea Kings.

I congratulate my hon. Friend on her excellent, sterling efforts to advocate on behalf of serving personnel and veterans, seeking answers on the important matter of military helicopters and blood cancers. Does she agree that although the current in-house testing of in-service helicopters is welcome, we must ensure full transparency on the matter so that there is work done for those who have previously worked on those helicopters? The health and wellbeing of our serving personnel must always be front and centre.

[Jayne Kirkham]

I agree absolutely. The health of our serving personnel is and always must be paramount. I will move on to previous cases shortly.

I know of 180 cases with solicitors of crew working on military helicopters who have contracted cancers, many like those of the two people I mentioned. They worked on the Sea King particularly, but also the Westland Wessex, the Puma, and the CH-47 Chinook. Many of the crew affected were in touch with each other, as there seemed too many of them, and the cancers too rare, to be pure coincidence.

Last July, a report was written by the Independent Medical Expert Group on medical and scientific aspects of the armed forces compensation scheme, and was published in November last year. There was a section at the end on the potential link between exhaust fumes such as benzene from helicopters and blood cancers such as multiple myeloma. The findings were that the evidence and data available did not meet their threshold to establish a causal link between Sea King helicopter exhaust fumes or benzene and multiple myeloma, leiomyosarcoma, and soft tissue sarcomas.

[Jim Shannon (Strangford) (DUP)]

I commend the hon. Lady for introducing this debate. In the short time that she has been in the House, she has made a real name for herself as an assiduous MP, and I wish her well in her efforts. I concur with her comments. For us in Northern Ireland, helicopters were a part of life for getting troops in, and the police in and out. Numerous cases have been settled out of court for aircrew who developed rare cancers after being exposed to helicopter exhaust fumes. Given that certain types of blood cancer can take 10 to 20 years to manifest themselves, does the hon. Lady agree that steps should be taken to encourage those who served in specific aircraft types to seek screening and early intervention to provide better outcomes?

With your indulgence, Sir Jeremy, on the question I asked earlier, there is a specific case of the Royal Ulster Constabulary in Northern Ireland. Those who did undercover work carried battery packs on their backs by their kidneys. Of a patrol of 12 policemen who did undercover work, 11 are dead. There is a big case to answer for all that happened in relation to helicopters and service in Northern Ireland.

[Jayne Kirkham]

I thank the hon. Member. He is correct that some cancers can take a long time to manifest. Personnel, veterans and those around them in their communities have to be aware that this could show itself much later in their lives.

Solicitors for some of the personnel point to an RAF Institute of Health report dated March 1999. Although it did not establish a causal link, it contained recommendations to reduce crews’ exposure to exhaust fumes. I understand that modifications to the aircraft to do that were not made, although they did take place on some other countries’ military helicopters.

Six cases in this country, including Zach’s, have so far been settled, and compensation paid by the Ministry of Defence without admission of liability. The Sea Kings were taken out of UK military service in 2018, and the Westland Wessex in 2003. Pumas and Chinooks are still in service, although the older aircraft have recently been retired. Sea Kings, however, are still in service in the private sector, and in military use in other countries. Three were donated by the UK to Ukraine in 2023. The MOD started testing exhaust emissions from military aircraft this February and has started the process of checking the records of personnel and veterans, to assemble data about how many have subsequently developed cancer. That will provide crucial data about who and how many people may have been affected.

[Ayoub Khan (Birmingham Perry Barr) (Ind)]

I thank the hon. Member for bringing this important matter to the attention of parliamentarians. It is not just about those who have contracted cancer. We know that other respiratory problems may also occur. Does he agree that our veterans, who do so much for our country, need the benefit of additional research to ensure all aspects are covered, not just those who have suffered cancer? I pay tribute to her late husband for his effort and involvement in the military.

[Jayne Kirkham]

I agree with the hon. Member that all manner of injuries may have occurred due to people’s military service. It is important that every single one is investigated to check if there is a link. I thank him for reminding me of that.

Due to the sheer number of records and the way they are stored, I understand that checking them could take weeks, if not months. There are a number of things that could be done by Government or further afield that could help people who are affected now or in future. First, the Government could help to spread awareness of this potential link. There will be men and women with initial symptoms of these cancers that can easily be missed. If the serving personnel and veteran communities, who served with or on these aircraft, are alive to the possible risks, they will know what symptoms to look out for and to raise with medics.

Secondly, GPS should be educated in places where there are clusters of personnel and veterans who have worked with these aircraft, so that they know to look for a military record when assessing symptoms that could indicate blood cancers. Thirdly, as well as signposting for veterans, a screening scheme for blood cancers could be set up for those who may be most at risk.

Fourthly, the MOD can move faster on assembling, analysing and releasing the data on how many service personnel and veterans have subsequently developed these cancers, so that more research can be done on causation, action can be taken and cases can be quickly concluded. The five-year survival rate for multiple myeloma is 50%, so people are dying before their cases are settled and many are still being turned down for compensation.

Fifthly, testing exposure to emissions must be done to take into account and replicate the real-life conditions that personnel were working under while undertaking search and rescue and military combat sorties. Sixthly, crews should still be advised to take sufficient precautions around aircraft, such as not standing directly in exhaust fumes and wearing personal protective equipment. Private companies and other countries that still use these aircraft need to be informed of the potential risks so that they can take steps to modify the aircraft and take other preventive action.

[Perran Moon (Camborne and Redruth) (Lab)]

I commend my hon. Friend for bringing us this really important debate. Does she agree that the Ministry of Defence has a duty not just to those people who have already died or those people who are currently suffering but to their family, friends and loved ones? They are the backbone of so much of our armed forces. We need to make sure that this issue is dealt with efficiently and in an open environment so that if there is an ongoing issue, it is dealt with transparently.

[Jayne Kirkham]

I agree that these things should be dealt with as swiftly as possible and that it is not just about current personnel and veterans but people who may be affected in the future.

Military personnel think they know the risks of what they are taking on when they sign up to fly for the military or work as aircrew. What they could not realise is that there were, and possibly still are, other hidden risks. The people who risk their lives in the service of this country are courageous men and women, and they deserve the very best care and the very best chance.
