Military Helicopters: Blood Cancers

Perran Moon Excerpts

Tuesday 8th July 2025 Westminster Hall

[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.

--- Later in debate ---

[Al Carns]

I thank my hon. Friend for raising that point. That is why we brought the armed forces covenant into law just two weeks ago, which now increases the number of Government Departments that have a responsibility to ensure that no one is disadvantaged because of their service from four to 14. That is fantastic. It also enhances the support that we can give to those serving, their families and loved ones, the bereaved, and our veterans in general.

The safety of our people is non-negotiable. To the families who have campaigned so passionately to raise awareness of this important topic, I say this: “You have sparked a conversation. It has resulted in action. That action and detail will follow through in due course.” But we must make an active move now to collect the data, as broadly as possible.

[Perran Moon]

It is good news that the Minister has identified the requirement to collect data, but data collection can take a long time. Is he able to give any comfort on the timescale for building up the evidence base to determine whether there is a direct link one way or the other?

[Al Carns]

Unfortunately, we do not have a timescale at the moment. The scale of the task is hard to define. In terms of where the records sit, no one keeps records on veterans when they leave, apart from the NHS. Those records are held in different buckets all over the UK. It is going to take some time to pull that together and analyse it, and to work out whether there are pockets of very rare cancers from one part of defence, another part of defence or from other industries. Unfortunately, we just do not know. I will endeavour to get back to my hon. Friend once the scale of the task, which is gigantic, is conceptualised into time.

I come back to some points raised by my hon. Friend the Member for Truro and Falmouth. On spreading awareness of a potential link, we work really hard to ensure that all service personnel have access to national cancer screening programmes. The MOD regularly runs health education campaigns—I hope that answers her earlier question—that encourage participation in national cancer screening programmes and raise awareness about cancers. Any veteran listening to this debate who has a cancer or a suspicion of cancer should please ensure they get it checked out and get the details recorded medically so that, if there may be a claim of any shape or form, that can be processed and they have the evidence, and it can get dealt with in the fastest and most efficient manner.

Educating GPs in places where there are clusters of personnel and veterans also goes back to data. There are clusters of veterans everywhere, ranging from 1,000 to 17,000, to 33,000 in Portsmouth. I will refrain from speaking about healthcare professionals any broader than the MOD in this forum, but I expect every defence medical service doctor to work in accordance with best practice, particularly National Institute for Health and Care Excellence guidelines, to identify individuals with symptoms that could be caused by cancer and to arrange the appropriate speedy follow-up for a specialist referral.

As well as signposting for veterans, a screening scheme for blood cancers could be set up for those who may be at most risk; that point was mentioned earlier. The current medical advice from IMEG is clear, but I am mindful that there is also no UK screening programme for multiple myeloma or other rare cancers. I have read some of the medical advice, and it looks like some of those screening processes can cause a percentage of harm—I will need to look at that in a bit more detail. Any harm from screening must be outweighed by the benefits of screening. I go back to causation, and a focus on getting data on who needs to be screened and who does not. This is a deeply complex problem. I am not trying to confuse or confuddle the debate. We need to get to the bottom of this, but we need to do it the right way, and in the speediest, most efficient way.

The real-life replication of testing conditions was also mentioned. I want to reassure hon. Members that the testing we do on aircraft mirrors real life. In some cases, it is on the sampling equipment that is carried on the person, on the air crew and indeed the ground crew as well, because not just the pilots are involved, but the broader group. On whether they should still be advised to take sufficient precautions, I should say that I have spent a large proportion of my career in helicopters and stood in the exhaust fumes, which often used to heat us up in cold environments, which I would not recommend. I can attest to the quality and professionalism of the air crew. Indeed, the air crew as a whole are absolutely prepared with both PPE and understanding.
