Medical insurers are moving to fill a void in perhaps the most important, and frightening, area of cover – cancer.
Market leader Bupa International has moved into an area which, until recently, has been seen by some insurers as unduly risky. It unveiled a plan whereby former sufferers of cancer, and other serious conditions, can be insured against the cost of treating a recurrence – albeit at a heavy premium loading.
However, the premium loading was modest, he claimed. The loading in breast cancer cases could be as low as £260, and for skin cancer £65. In the event of the disease recurring, all treatment costs would be covered subject to high annual limits, usually £2 million.
