DCIS and Critical Illness Cover

DCIS is a very early form of breast cancer where abnormal cells are found inside the milk ducts but haven't spread into the surrounding breast tissue. It's often picked up through routine breast screening rather than because of symptoms. Because it's found so early, it's usually very treatable. If you've been diagnosed, your consultant and breast care team are the best people to talk to about your treatment. This guide only covers how your insurance may respond.

Critical illness policies pay a lump sum when you're diagnosed with a condition that meets the policy's definition. For cancer, a full payout usually requires the cancer to be invasive, meaning it has spread beyond where it started. Because DCIS hasn't spread, it typically doesn't meet that full definition. Historically, that could have meant no payment at all. Today, many policies include an additional or partial payment specifically for conditions like DCIS.

• An additional payment is a set amount, usually a percentage of your sum assured, paid when you're diagnosed with a less advanced condition such as DCIS.
• Recent research by Newspage, sponsored by Check Financial, found that critical illness cover pays between 25% and 50% of a £100,000 plan for early-stage breast cancer or DCIS, depending on the insurer and the plan.
• On many plans this payment doesn't reduce your main sum assured. If you're later diagnosed with something else, or the condition progresses, you could still claim your full cover.
• Insurers differ on how much they pay, any cap on the amount, and the conditions that need to be met (for example, the type of treatment received). Your policy wording sets out the exact terms.

Additional payments for DCIS from selected insurers (Newspage research, October 2026)

Based on research published by Newspage in October 2026. Policy terms change and the amount paid depends on your plan, the policy wording and the circumstances of your claim. This is not a recommendation of any insurer.

Critical illness cover has improved a lot over the years. Some older plans don't include carcinoma in situ at all, while many policies available today do. If you took out your cover several years ago, it's worth having it reviewed to see whether a newer plan would give you broader protection. Don't cancel an existing policy before any replacement is in place, as your health and circumstances may have changed since you first took it out.

• Contact your insurer, or the adviser who arranged your policy, as soon as you feel able. Many people don't realise an additional payment is available.
• Ask whether your policy includes a payment for carcinoma in situ of the breast and what evidence is needed.
• Check whether the payment reduces your main cover. On many plans it doesn't.
• Think about how you'll use the money. It can help with time off work, childcare, travel to and from hospital, private treatment or day-to-day bills while you recover.
• If you have income protection or sick pay through your employer, check what those pay too, as a lump sum is a one-off and income may still be affected.
