How critical illness cover can pay up to £50,000 extra for early-stage breast cancer

Women diagnosed with the earliest form of breast cancer, ductal carcinoma in situ (DCIS), can claim between a quarter and half of their critical illness cover — up to £50,000 — without touching the main payout, new research by Newspage, sponsored by Check Financial, has found.

All five of the large insurers checked pay DCIS as an “additional” payment. On a £100,000 policy that means £25,000 to £50,000 now, and the full £100,000 still available if the cancer progresses or another covered condition is diagnosed later.

But the caps bite hardest on women with the most cover: £25,000 is a quarter of a £100,000 policy and a twentieth of £500,000.

Aviva Critical Illness Plan and Legal & General Critical Illness Cover pay 25%, capped at £25,000.

Royal London Critical Illness Cover pays up to 50%, capped at £35,000. Zurich Personal Protection’s enhanced level and Guardian Critical Illness Protection pay 50%, capped at £50,000.

Additional payout

Oliver Jordan, Director at Watford-based Check Financial, said you need to make sure you claim any additional payment.

He added: "Usually the type of claim which has justified an additional payment rather than a full claim is deemed less invasive or less severe. To get the most value out of your insurance, you would want to claim an additional payout.

"It doesn't affect your overall sum assured so if you are unlucky enough to be diagnosed with something else or the condition progresses, you could claim in full too. This means someone with £100,000 of cover with Guardian could claim £50,000 for cancer in situ of the breast, if this then progresses to stage 1, you could then claim the full £100,000. £150,000 in total. 

“The bigger concern is where providers aren't covering this at all. A simple comparison between the worst critical illness cover policy on the market with the best from 15 years ago shows the worst policy today is more comprehensive. Things like carcinoma in situ aren't covered at all by older plans. What is also concerning is future improvements meaning it is vital to regularly update your cover.”

Michelle Lawson, Director at Fareham-based Lawson Financial, said it was an “excellent inclusion in a policy”.

She added: "Sums payable do differ from insurer to insurer as do the terms and conditions of the point of payout and the policy wording itself. However, this cover is usually in addition to the standard sum insured and doesn't affect any future subsequent claims. 

“Most claim payouts for this would be the lower of the sum insured or a set figure. This benefit can be used to bridge a gap for time off work, childcare, transport to and from hospital, private medical treatment, among other things that impact daily life following a diagnosis.”

Careful

Scott Gallacher, Director at Leicester-based Rowley Turton, said additional payments are “an improvement in critical illness cover”.

He added: "Critical illness policies were originally designed to pay when someone suffered a defined condition meeting specified severity criteria. An early diagnosis such as DCIS may not meet the definition for a full cancer payout. Historically, that could have meant no payment at all. 

“Partial or additional payments therefore improve these policies, broadening cover rather than reducing it. In many cases, the balance of the main sum assured also remains intact, so the policy can still potentially pay the balance later if a more serious condition meets the definition.”

Harvey Dhillon, Founder & CEO at Zmartly, said you need to be careful with the money if you get a payout.

He added: "The gap worth worrying about is the one between that payment and the income you lose while you're off work. On a policy you own, the lump sum isn't taxed as income. Employees now get Statutory Sick Pay from the first day off, but that's only the legal minimum, so ask what your employer adds. 

“The self-employed get no sick pay, and the Self Assessment bill due on 31 January can include an advance on this year's tax based on last year's bill. If profits drop this year, they can claim to cut that advance, though going too low means interest on the difference. Don't spend the lump sum until you've listed the bills due while your pay is down.”

Early-stage breast cancer and critical illness cover: your questions answered

Oliver Jordan, Director at Check Financial, the adviser behind this research, answers the questions readers most often ask about DCIS and critical illness insurance. Updated 11 October 2026.

What is DCIS, and why do critical illness policies class it as a “less advanced” cancer? 

DCIS stands for ‘ductal carcinoma in situ’. It’s a very early form of breast cancer where abnormal cells are found in the milk ducts but haven’t spread into the surrounding breast tissue. “In situ” literally means “in place”, in Latin. Because the cancer hasn’t spread, insurers put it in the “less advanced” or “early-stage” category rather than treating it as a full critical illness claim. That’s not the insurer saying it isn’t serious — it’s a technical distinction about how far the cancer has progressed. And clearly it is still cancer, which can be frightening. But it has been caught very early, which is a positive. The practical effect is that most policies pay a partial amount for DCIS rather than the full sum assured.

If I’m diagnosed with DCIS, what will my policy actually pay — and does that payment come off my main cover?

Most policies these days will pay what’s called an additional payment. That’s usually a percentage of your sum assured, with a cap — usually somewhere between a quarter and a half of your cover, up to a fixed maximum. The important bit is that it’s paid as a completely separate claim. On most policies it doesn’t reduce your main cover, so if you later needed to claim for a condition under the full-payout definitions, or another additional-payment condition, you’d still be covered in full. Always check your own policy’s unique wording, because the percentage and the cap vary from insurer to insurer.

Do I have to have surgery before I can claim, and does it matter whether it’s a lumpectomy or a mastectomy?

Usually, yes. Most policies require the DCIS to have been removed by surgery before an additional-payment claim will be accepted. A diagnosis in itself usually isn’t enough. The definition in your policy will say what treatment it expects, and that wording differs between insurers, so it’s worth reading the exact line rather than assuming. Whether it’s a lumpectomy or a mastectomy, the key question is whether the surgery meets your policy’s definition. If you’re unsure, ask the insurer’s claims team or an adviser to check the definition against your treatment plan before you claim.

After a DCIS payout, does my policy carry on — and could I still claim in full for a later invasive cancer?

Provided your policy pays DCIS as an “additional” claim — and many policies these days do — then yes, your cover carries on afterwards. You’d still be covered for the original value of your plan, or the current value if you have increasing or decreasing cover. So if the cancer later progressed, or you were diagnosed with something else covered under the full-payout definitions, you could claim in full on top of the earlier payment. Where you need to be careful is older policies, where an early-stage payment might have been deducted from the main cover. Check which type you have.

How do I find out what my own policy pays for DCIS, and what should a woman taking out cover today look for?

Look at the definitions section of your policy document, usually under “additional payments” or “less advanced cancers”, and find carcinoma in situ of the breast. It will tell you the percentage, the cap, and whether surgery is required. If the document is hard to follow, an adviser can read it for you. If you’re taking out cover today, the things to compare are how clear the cancer definitions are, how early-stage cancers are paid, whether the payment comes off your main cover, and the insurer’s record on paying breast cancer claims quickly.

These answers are general information, not personal advice. Always check your own policy wording or speak to a regulated adviser.
