Scottish Provident paid out 93% of all critical illness claims in 2012.
The provider's ‘Critical illness claims report' said this represents a pay out of over £94m. Just 2% of claims declined for non-disclosure.
The average pay out was £88,975, with the largest claim for £1m.
Cancer claims remained the top reason for making a critical illness claim, accounting for 60% of all claims. Cancer payments amounted to nearly £57m. Of the 31 different types of cancers claimed for, a third of all cancer claims were for breast cancer.
Jennifer Gilchrist, senior product development manager, Scottish Provident said: "As the most common cancer in the UK it comes as no surprise that breast cancer accounts for a third of our cancer claims.
"On the positive side improved treatment and early diagnosis means that survival rates for this type of cancer are set to increase by as much as 28% by 2030."
