Key Takeaway
Supplemental cancer insurance companies include Aflac, Colonial Life, Mutual of Omaha, Physicians Mutual, Washington National and ManhattanLife. The best choice depends on whether you buy at work or on your own, how the plan pays, and the company’s financial strength and claims record.
Dozens of companies sell supplemental cancer insurance, and many of their plans look alike at first glance. The real differences show up in how a company designs its benefits, how it handles claims, how it sells, and how financially strong it is.
This guide gives you a simple way to vet any company, with examples from well-known carriers. For a list of companies with ratings, see our cancer insurance providers page. Keep one rule in mind with every company: supplemental cancer insurance is limited-benefit coverage that pays cash on top of your health plan. It does not replace health insurance.
