Yes, you can sometimes get life insurance after cancer, but how long you need to wait depends on the insurer and on the cancer. Aviva says "Having cancer doesn’t always rule out cover, each application is looked at individually, based on the type of cancer and your medical history".

If you would like to talk anything through, the Macmillan Support Line is free and confidential for anyone living with or affected by cancer: 0808 808 00 00, 8am to 8pm, seven days a week, or see macmillan.org.uk.

Below is what insurers have put in writing about applying once treatment has ended. A decision on you depends on your own medical records, which no general guide can weigh. When you want a view on yours, use this page’s form; there is no charge or obligation, and an FCA-authorised broker rings you back.

How long do insurers say you need to wait?

There is no single waiting period, and the two insurers quoted here describe the wait in different ways.

Aviva’s page on life insurance and cancer (last updated 12 May 2026) says "Many providers won’t offer cover until at least a year has passed since your last treatment, so it’s possible you may not be eligible right away". That is a general remark about providers, not Aviva’s own rule for any cancer, and it adds that the criteria "can depend on the type of cancer you’ve had and whether you’re still undergoing treatment".

Vitality gives more detail, in an entry on cancer on its website for financial advisers (undated, read 20 October 2026). "All tumours are assessed individually", the entry begins, and then, as a guide to the most common outcomes: "For most cancers there will be a postponement period of up to four years for Life Cover". After that, higher premiums known as temporary ratings apply "for up to the first 12 years of the plan term", and "The more recent the cancer, the higher the rating". Then: "12 years after treatment has been completed and provided there has been no recurrence, Life Cover can usually be accepted at standard rates". Where cancer has spread beyond the organ where it began, "most cases will be declined".

Those are one adviser-facing guide’s typical outcomes, not a promise to any applicant and not a rule for the market. Other insurers may set different timings, which is one reason to ask more than one. Keep in mind that being "after treatment" and still having treatment are different things: if you are in treatment now, buying life insurance during cancer treatment has its own page.

What do insurers want to know about the cancer?

Vitality says it needs "Location and type of tumour, and whether it has spread" and "Date of diagnosis and date treatment stopped". It may then ask for a GP report to establish the size, grade and stage of the tumour, which it uses for the final rating.

Macmillan’s guidance on insurance and cancer (last reviewed September 2023; Macmillan says the page is now being reviewed) says insurers may ask whether the cancer can be cured, and that "If you find this difficult, you might want to ask an insurance broker or financial adviser to look for policies for you instead". A list of the dates and details you will probably be asked for is in medical questions for life insurance.

What can an insurer decide?

Legal & General’s Underwriting explained leaflet (W10188 09/25) lists cancer alongside heart disease, diabetes and stroke as conditions it looks at when assessing risk. Its section on postponement is the one most relevant after treatment: a serious medical event in the recent past, with cancer and a heart attack as its examples, is a reason it may hold off, and it undertakes to say when a fresh application can be looked at.

A postponement is therefore not a final no. Macmillan describes the same idea: an insurer may turn you down for now while you are having tests or treatment, and "may agree to review your application when you know about your diagnosis or finish treatment". If you are postponed, ask when you can reapply.

Besides standard terms and postponement, the leaflet’s other outcomes, written for life, critical illness and income protection cover together, are an increased premium, benefits changed, an exclusion, or no cover offered, the last for a risk it sees as both too high and lasting. The same guidance says an insurer can decline or charge more "only if they have the evidence to show you are more likely to claim".

The law sits behind that. As the guidance puts it, "Cancer is recognised by law as a disability", under the Equality Act 2010 in England, Scotland and Wales and the Disability Discrimination Act 1995 in Northern Ireland. Insurers have different rules from other services: they may treat someone differently because of a disability that raises the risk of a claim, but only where the assessment rests on relevant information from a reliable source and the treatment is reasonable. "If asked, the insurer has to provide evidence to show they have met these conditions."

Does the type of cancer matter, such as breast or thyroid?

Insurers say it does. Aviva’s page says the decision is "based on the type of cancer and your medical history", and Vitality’s entry asks for the type, the spread, the size, grade and stage. The insurer pages quoted here describe one general approach rather than separate timings for breast, thyroid, bowel or blood cancers. Ask about your own type and stage, ideally through a broker who can put the same details to several insurers.

What about mortgage cover?

Cover that pays off a mortgage if you die is life insurance in a different shape, so the questions above apply to it as well; how mortgage life insurance works explains the product. What, if anything, your lender expects you to hold is a question for the lender or your broker.

What must you tell an insurer?

Macmillan says "You usually have to tell insurance companies about pre-existing conditions such as cancer". Aviva’s page says that if you are diagnosed after your policy starts you "usually don’t need to let your insurer know, unless additional benefits apply". The legal duty on what you say at application, and what an insurer may do about a wrong answer, are set out in what you must disclose and when an insurer can refuse to pay.

What if you are postponed or declined?

A postponement or decline from one insurer leaves the others to ask. The page on life insurance with medical conditions covers what insurers can decide generally and the voluntary industry agreement on referring declined applicants. What to do if you are declined takes the next steps. A broker can ask several insurers on your behalf, though none can promise an offer, and the form here is there for whenever you want it.

Some cover is sold without any health questions; it works differently and comes with its own trade-offs, which guaranteed life insurance sets out.

Frequently asked questions

How long after cancer can I get life insurance?

It varies. Aviva’s page says many providers will not offer cover until at least a year after your last treatment, and Vitality’s adviser entry gives, as a guide for its own Life Cover, a postponement of up to four years for most cancers. Only an insurer can say what applies to you.

Can I get life insurance after breast cancer?

Possibly, depending on the insurer and the details of the cancer, such as its type, stage and when treatment ended. The insurer pages quoted here give no breast-specific timing, so ask a broker or insurer about yours.

Is life insurance more expensive after cancer?

It can be. Macmillan says an insurer may ask for a higher premium where it has evidence you are more likely to claim, and Vitality describes temporary ratings after a postponement, higher the more recent the cancer. A price comes only from a quote on your own details.

Do I need to tell my insurer if I get cancer after taking out a policy?

Aviva says you usually do not need to let your insurer know, unless additional benefits apply. Check your own policy wording.

When you feel ready, the enquiry form here costs nothing: it asks an FCA-authorised broker to ring you about your history.
