Health insurance after cancer what's covered and what isn't

If you've had cancer, you can still take out private health insurance. Insurers won't turn you away because of a cancer diagnosis in your medical history, but they will treat your application differently to someone with no cancer history.

Once cancer is in your medical records, it becomes what insurers call a pre-existing condition. This means the specific cancer you've had, and sometimes conditions an insurer considers related to it, are usually excluded from your policy. Everything else, including new health issues that develop after your policy starts, is covered in the normal way.

This distinction matters because private health insurance is designed to cover new, unexpected conditions. If a health issue is already known about before your policy begins, it can't be treated as new. That's why your previous cancer typically falls outside your cover, at least to start with.

When you apply for health insurance, you'll typically choose between two ways insurers assess your medical history: moratorium underwriting and full medical underwriting.

Moratorium underwriting

With moratorium underwriting, you don't declare your full medical history upfront. Instead, the insurer looks back a set period, usually five years, and automatically excludes anything you've had symptoms of, been treated for, or received advice about in that time.

If you go two continuous years on cover without any symptoms, treatment, or advice related to that condition, the exclusion may lift. For a diagnosis like cancer, this route can work if your treatment finished several years before you apply, but it rarely helps if your diagnosis or treatment is more recent.

Full medical underwriting

With full medical underwriting, you disclose your complete medical history when you apply, including your cancer diagnosis, treatment, and current status. The insurer reviews this and confirms in writing exactly what's excluded before your policy starts.

For most people with a cancer history, full medical underwriting gives more certainty. You'll know from day one whether your specific cancer is excluded, whether related conditions are excluded too, and what you're covered for immediately.

Exactly what's excluded depends on your insurer, your specific cancer, and how long ago you were treated. As a general rule:

• The original cancer you were diagnosed with is usually excluded, sometimes permanently
• Conditions an insurer considers directly related to that cancer may also be excluded
• New, unrelated conditions, including different types of cancer, are covered from the start of your policy
• Ongoing NHS care for your original cancer continues as normal - private health insurance doesn't replace or affect your NHS entitlement

Some insurers take a broader view of what counts as "related" to your original cancer than others. Before you buy, ask exactly what would and wouldn't be covered if your cancer recurred or if you developed complications linked to your original diagnosis.

All the major UK health insurers will consider people with a cancer history, but some are more accommodating than others when it comes to underwriting and cover for related conditions.

The Exeter is often highlighted by advisors for its flexible approach to pre-existing conditions. Its fixed moratorium option and willingness to look at complications individually can work in your favour if you've had cancer in the past.

Freedom Health Insurance takes a more personalised approach to underwriting and is worth considering if you've been declined or heavily excluded elsewhere.

Bupa offers a large hospital network and a direct access service for cancer concerns, meaning you can see a specialist without a GP referral for anything outside your exclusions.

Vitality and AXA Health both offer comprehensive cover for new conditions, alongside wellness programmes and flexible policy structures.

No two insurers assess cancer history in exactly the same way. One insurer might exclude your specific cancer type entirely, while another offers cover with fewer restrictions. Comparing a wide range of insurers, rather than applying to just one, gives you the clearest picture of what's realistically available.

Being declined for health insurance because of a cancer history is uncommon, but you might face more exclusions than you'd hoped for. If that happens, you still have options.

Try a different insurer. Insurers assess risk differently, and one that excludes your cancer type heavily might be more generous with a different applicant. An advisor can point you toward insurers more likely to offer suitable terms.

Consider moratorium underwriting. If full medical underwriting resulted in a permanent exclusion, moratorium underwriting might offer a path to cover after two continuous symptom-free years, depending on how recently you were treated.

Look at health cash plans. These reimburse routine healthcare costs like dental and optical care and don't ask health questions, though they don't cover hospital treatment or major illness.

Consider over 50s life insurance for wider protection. If you're looking for cover that doesn't ask health questions at all, some over 50s life insurance policies accept applicants regardless of medical history, including a previous cancer diagnosis. This isn't a substitute for health insurance, but it's worth understanding as part of your wider financial planning.

Whatever your circumstances, private health insurance doesn't replace or affect your NHS entitlement. You'll continue to receive NHS care for your original cancer and any ongoing monitoring, regardless of what your private policy covers.

Having a cancer history doesn't automatically make your health insurance more expensive. Premiums are mainly based on your age, location, and the level of cover you choose, not your medical history. A cancer history affects what's covered, not how much you pay for the policy itself.

That said, costs vary considerably between insurers and cover levels. As a guide:
