Cancer insurance is a type of supplemental health insurance that is meant to manage the risks associated with the cancer disease and its numerous manifestations. Cancer insurance is relatively new trend within the insurance industry at large. It is meant to mitigate the costs of cancer treatment and provide policyholders with a degree of financial support. This support is based upon the terms written into a particular policy by an insurance company. As with other forms of insurance, cancer insurance is subject to charges, called premiums, which change depending on the risk associated with covering the disease.
