- The Foreign, Commonwealth and Development Office states that travellers must declare existing conditions or pending treatment or tests, and warns that failing to declare something may invalidate travel insurance.
- ABI member insurers paid 262 million pounds in travel medical claims during 2024, with an average medical claim of 1,528 pounds; one member paid over 1 million pounds for a single USA hospitalisation and repatriation.
- A free UK GHIC covers medically necessary state healthcare in the EEA but does not cover repatriation, private treatment or ski and mountain rescue, and is not a replacement for travel insurance.
- The Money and Pensions Service runs a travel insurance directory of specialist providers for people who struggle to find cover because of a medical condition.
- Specialist insurers such as AllClear state they can cover over 1,300 conditions, including all cancer types and stages.
A cancer diagnosis, current treatment, or a history of treatment within recent years must be declared during medical screening, even where a traveller is in remission or has been told they are cancer-free. Insurers including Staysure and AllClear state that an undeclared condition can leave a related claim unpaid or a policy invalidated.
How cancer cover differs from standard travel insurance
A cancer diagnosis is treated by insurers as a pre-existing medical condition. Standard off-the-shelf policies frequently exclude claims arising from a pre-existing condition unless that condition has been declared and accepted in advance. The practical consequence is that a traveller who buys an unscreened policy may hold cover that excludes the single event most likely to generate a large overseas bill: a cancer-related medical emergency.
The Foreign, Commonwealth and Development Office is explicit on the point. Its foreign travel insurance guidance instructs travellers to declare existing conditions or pending treatment or tests so that they are covered, and warns that failing to declare something may invalidate travel insurance. The same guidance asks travellers to confirm that a policy covers treatment in state or private hospitals, emergency transport such as an ambulance (often charged separately), and repatriation costs.
Why this matters financially is visible in the claims data. The Association of British Insurers reported that its members paid 472 million pounds across more than 500,000 travel claims in 2024, of which 262 million pounds were medical claims. The average medical claim was 1,528 pounds, and one insurer paid over 1 million pounds for a customer admitted to hospital for emergency treatment in the USA who then required repatriation. For a cancer traveller, a policy that excludes the condition removes protection against exactly that scale of cost.
Why medical screening matters
Specialist cancer cover is built around medical screening. Rather than excluding the condition, the insurer asks structured questions about it and then prices the policy to include it. AllClear describes its screening around a medical warranty that captures conditions for which a traveller has, in the last two years, taken prescribed medication or received medical treatment or advice at a hospital, clinic, GP surgery or via remote consultation. Staysure similarly asks travellers to declare a cancer diagnosis and treatment within recent years, even where the traveller is currently in remission or cancer-free.
Screening typically covers the type of cancer, the dates and nature of treatment, whether treatment is ongoing, and the current outlook. Providers commonly route travellers who are waiting for treatment, undergoing treatment, or living with a terminal diagnosis to a phone line rather than an instant online quote, because those cases need individual assessment. The aim of screening is to produce a policy whose terms reflect the actual condition, so that a later cancer-related claim is not met with a pre-existing condition exclusion.
What to look for
The features that matter most for a cancer traveller are the ones that respond to a serious overseas medical event. Emergency medical and repatriation limits sit at the top of that list. The FCDO highlights repatriation specifically because flying a patient home, sometimes with medical escort, is among the most expensive outcomes of a trip abroad and is not covered by a GHIC.
Beyond the medical limit, the relevant points include whether the policy covers cancellation if a health change before departure prevents travel, whether it covers ongoing or recently completed treatment, whether the medical excess applies to a cancer-related claim, and the maximum trip length the policy allows. The FCDO also notes that some insurers may waive the medical excess where a traveller uses a GHIC. A GHIC remains a useful companion document because it gives access to medically necessary state healthcare in the EEA, but the NHS is clear that a GHIC is not a replacement for travel insurance and does not cover repatriation or private treatment.
Cover limits and exclusions
Cover limits on specialist policies are tiered. AllClear publishes emergency medical and repatriation limits of up to 10 million pounds on its Gold tier, up to 15 million pounds on Gold Plus, and unlimited cover on Platinum. Staysure states that unlimited emergency medical expenses cover is available on its Comprehensive and Signature tiers, and that it covers travellers of all ages with no upper age limit. Both providers stress that cover for a cancer-related claim depends on the condition having been disclosed and accepted at screening.
Common exclusions persist even on a screened policy. Claims arising from a condition that was not declared, travel undertaken against medical advice, and travel booked when a traveller was already unfit to travel are typical exclusions. A GHIC-style state card does not fill these gaps: it excludes repatriation, treatment in a private medical facility, and ski or mountain rescue. Reading the policy wording and the insurance product information document for the specific tier remains the only reliable way to confirm what a given policy covers.
Providers offering cover in this segment
Two FCA-regulated specialists publish dedicated cancer travel insurance products that screen the condition rather than excluding it.
AllClear arranges cover through IES Limited and administers it through AllClear Insurance Services Limited (FCA firm reference number 311244). It states it can cover over 1,300 different conditions across all cancer types and stages, that 99 percent or more of its customers are offered cover, and that it can offer cover even where cancer is terminal. Its tiered medical and repatriation limits run up to unlimited on the Platinum tier.
Staysure is a trading name of TICORP Limited (FCA FRN 663617), authorised and regulated in Gibraltar. Its cancer page lists breast, prostate, skin, bowel, lung, cervical, ovarian, lymphoma and leukaemia among the cancers it can cover subject to screening and acceptance, covers travellers of all ages, and offers unlimited emergency medical expenses cover on its Comprehensive and Signature tiers.
Travellers who cannot obtain a quote from a single insurer, or who are quoted a price they cannot meet, are signposted by the Money and Pensions Service to its directory of specialist providers, described below.
Common pitfalls
The most damaging mistake is non-disclosure. Buying a cheaper unscreened policy and assuming a cancer-related emergency will be paid leaves a traveller exposed to exactly the exclusion the FCDO warns about. A related pitfall is assuming remission removes the need to declare; specialist insurers still require a recent cancer history to be disclosed.
Other recurring issues include relying on a GHIC alone, overlooking the cancellation limit when a pre-departure health change is a real possibility, missing a maximum trip length cap on a longer holiday, and failing to check whether ongoing treatment is covered. Buying through a screened phone quote for a complex or terminal case, rather than forcing the situation through an online form, often produces a more accurate policy.
Do I have to declare cancer if I am in remission?
Yes. Specialist insurers including Staysure and AllClear state that a cancer diagnosis and recent treatment must be declared even where a traveller is in remission or has been told they are cancer-free, because an undeclared condition can leave a related claim unpaid.
Does a GHIC cover cancer treatment abroad?
A UK GHIC covers medically necessary state healthcare in the EEA, which can include treatment for a pre-existing condition, but the NHS states it does not cover repatriation or private treatment and is not a replacement for travel insurance.
Is there a maximum age for cancer travel cover?
Staysure states it covers travellers of all ages with no upper age limit. Limits and pricing still depend on the outcome of medical screening for the individual condition.
What if no insurer will cover me?
