Whether critical illness cover pays out for breast cancer turns on your own policy's cancer definition. Zurich, Legal & General and Aviva's Critical Illness Plan word theirs as the ABI model does: a malignant tumour confirmed by histology that has invaded tissue, with cancer in situ left out. Some add a separate, smaller payment for carcinoma in situ of the breast, set out below insurer by insurer.
If you or someone close to you has breast cancer, Macmillan Cancer Support's Support Line is on 0808 808 00 00 and is open seven days a week from 8am to 8pm. Breast Cancer Now's nurses can be reached on 0808 800 6000.
This page is about policy wording, not about what a diagnosis means for anyone. Buying new cover during or after treatment is a separate question, taken up in critical illness cover after cancer.
Having someone read through the cancer clauses of your shortlist may be useful. On a free call-back, an FCA-authorised broker can compare those clauses with you; you request one with the form on this page.
How do critical illness policies word the main cancer claim?
The ABI's Guide to Minimum Standards (16 September 2022, updated April 2023) says: "The three core conditions covered by all critical illness insurance policies are cancer, heart attack and stroke, and they must be covered to at least the standard model wordings set out in this Guide." Breast cancer is not named in that core definition; a breast tumour is tested against the same cancer wording as any other. The minimum standards explain what that guide does and does not fix.
Zurich's terms and conditions for its Personal Protection policy (PW720480017 04/26) head the cancer claim "Cancer – excluding less advanced cases" and open it with: "Any malignant tumour positively diagnosed with histological confirmation and characterised by the uncontrolled growth of malignant cells and invasion of tissue." Zurich's "not covered" list under that heading includes cancer in-situ, alongside pre-malignant growths and those of borderline malignancy or low malignant potential, as classified from the tissue.
Legal & General's Policy Terms and Conditions (October 2026) carry the same heading and opening sentence, with a matching exclusion for cancer in situ. Aviva's Critical Illness Plan conditions (May 2023) do too, and its list of what is not covered also names non-invasive cancers.
So the first test, for a breast cancer as for any other, is whether the diagnosis fits that wording as a whole, and the policy's other conditions apply as well: Zurich, for example, pays on a covered condition only if the person survives for at least ten days. Critical illness cover for cancer goes through the other exclusions, such as prostate and skin.
What do the policies say about DCIS and carcinoma in situ of the breast?
DCIS stands for ductal carcinoma in situ. Macmillan says: "DCIS is the earliest changes to cells which might then become breast cancer." It adds that the abnormal cells are contained in the ducts and lobules and have not spread into surrounding breast tissue, and that treatment is usually recommended to stop it developing into breast cancer. Its page was last reviewed on 1 October 2023.
The ABI's glossary describes cancer in-situ as malignant or cancerous cells that "have not spread into surrounding healthy tissue". The ABI's model cancer wording, by contrast, asks for "invasion of tissue" and lists cancer in situ among the cancers it does not cover. In the Zurich, Legal & General and Aviva wordings, what counts is how the tissue is histologically classified.
Whether an insurer would treat your own pathology report as carcinoma in situ of the breast, or as something else, is judged against the policy in front of it; a broker can talk through how that wording reads in practice when they call you back from the form.
Which policies make a smaller payment, and how much?
| Condition as headed | Insurer and document | Amount |
|---|---|---|
| Less advanced cancer of the breast – with surgical removal | Zurich, Personal Protection terms (PW720480017 04/26) | With a lump sum pay out, £25,000, or 25% of the sum assured if that is less |
| Carcinoma in situ of the breast - treated by surgery | Legal & General, terms (October 2026) | 25% of the amount of cover, capped at £25,000 |
| Carcinoma in situ of the breast – requiring surgery to remove the tumour | Aviva, Critical Illness Plan conditions (May 2023) | £25,000, or 25% of the cover amount if that is less |
| Less advanced cancer of the breast | Aviva, Life Insurance+ summary (February 2026) | On level and decreasing cover, £25,000 or 25% of the cover amount, whichever is lower |
| Carcinoma in situ (listed without naming an organ) | Scottish Widows, Protect summary (January 2026) | 25% of the cover, up to £30,000 |
The wording behind the headings differs. Zurich's additional payment condition covers "A positive diagnosis with histological confirmation of either of the following that has been treated by surgery to remove the tumour": cancer in situ of the breast, or a neuroendocrine tumour of the breast without lymph node involvement or distant metastases classified as WHO grade 1.
Legal & General's definition is "The undergoing of surgery on the advice of a hospital consultant to remove a tumour following the diagnosis of carcinoma in situ of the breast." It adds that "Any other type of treatment" is not covered. Aviva's is "Carcinoma in situ of the breast positively diagnosed with histological confirmation by biopsy together with the undergoing of surgery to remove the tumour."
All three tie the payment to surgery to remove the tumour. Scottish Widows' summary lists its condition and points to the policy provisions for the definition. Each figure is that insurer's own, for that document, and none is a market rule. The Aviva and Scottish Widows documents come from those insurers' adviser websites, and the Scottish Widows summary is for all customers except those using an aggregator; a policy bought through another channel can carry different terms.
Laying those headings, amounts and surgery requirements next to the policies on your own shortlist is something a broker can do on a free call-back requested through the form.
Does a smaller payment use up the rest of the cover?
Zurich says an Additional Payment leaves the policy running with no change to the sum assured, and gives a worked example: on a £130,000 sum assured, less advanced cancer of the breast pays £25,000, a later stroke meeting the stroke definition pays the full £130,000, and the policy then stops. It also says: "If you make a claim that meets the definition of a Full Payment condition and for an Additional Payment condition at the same time, we’ll only pay the claim for the Full Payment condition."
Legal & General says claims paid under additional cover won't reduce your amount of cover or change your premiums, and you can claim once per condition. It makes no additional payment when one spell of investigation and treatment produces more than one diagnosis and a full claim is open to you.
Scottish Widows says its policy continues after an additional payment, and that it will consider more than one claim if the carcinoma in situ is for a different organ or tissue to any previous claim. Aviva's Life Insurance+ summary says each person covered can claim for each additional critical illness once.
Where do you check your own policy, and what should you tell an insurer?
The wording that governs a claim is in your own policy conditions and schedule, not on this page. The pages on what critical illness cover is and on what you must tell a life insurer cover the basics, and other cancers have their own pages, such as prostate cancer and skin cancer.
If you have been declined or postponed because of breast cancer, a broker can ask specialist insurers about your circumstances, though no one can promise cover; life insurance with medical conditions explains the wider picture. This is part of the critical illness and income guides.
Whenever you feel ready, a broker can ring to talk through how these policies get assessed, with no fee; you ask for that through the page's form.
Frequently asked questions
Is breast cancer a critical illness?
Cancer is one of the three core conditions the ABI says every critical illness policy covers to at least its model wording. The wording quoted above does not single out breast cancer, so whether a particular diagnosis qualifies depends on whether it meets that cancer definition or one of the smaller-payment conditions in the policy.
Does Zurich critical illness cover pay out for breast cancer?
Zurich's terms (PW720480017 04/26) have the main cancer definition, which excludes cancer in-situ, and an additional payment condition for "less advanced cancer of the breast – with surgical removal", with £25,000 or 25% of the sum assured, whichever is less. Which of those a diagnosis falls under is decided against your own policy.
Do I have to tell an insurer about a breast screening result or biopsy?
The questions on an application differ from insurer to insurer, and the legal duty is explained on the page about disclosure when you apply. A broker can read the questions through with you before anything is sent.
Can I get critical illness cover if I have had breast cancer?
That depends on the insurer's assessment of your history, which this page cannot predict. Critical illness cover after cancer sets out what insurers publish.
