Key Takeaway
The best supplemental cancer insurance depends on how you want to be paid. Lump-sum plans such as Aetna and HealthSpring pay one large check at diagnosis, while scheduled plans such as Aflac pay cash through months of treatment. Pick a highly rated insurer, a benefit sized to your out-of-pocket gap and riders you will actually use.
There is no single best cancer policy for everyone. A 30-year-old with a high-deductible plan at work, a self-employed parent on an ACA Marketplace plan and a retiree on Medicare all need different things from the same kind of coverage. What they share is a gap between what health insurance pays and what cancer actually costs.
This guide ranks options by the need they fill best, explains the two ways plans pay, and gives you a short process for choosing. For a broader look at the market, see our list of the 5 best cancer insurance policies. Every plan here is supplemental, limited-benefit cancer insurance. It pays you cash and does not replace health insurance.
