Critical Illness vs Cancer Insurance Comparison
Critical illness insurance pays a lump sum on diagnosis of any covered condition (heart attack, stroke, cancer, major organ failure). Cancer-only policies pay only on cancer diagnosis. Compare premium, coverage breadth, and payout per dollar of premium.

What Critical Illness Insurance Covers
Critical illness (CI) insurance pays a lump sum on diagnosis of any covered condition. Standard policies cover: heart attack, stroke, cancer (all stages or only invasive), major organ failure, kidney failure, paralysis, ALS, and sometimes Alzheimer's, Parkinson's, MS. Aflac, Mutual of Omaha, Globe Life, and Cigna offer CI policies.
The lump sum payment is in addition to health insurance. Health insurance covers medical bills; CI covers lost income, copays, deductibles, experimental treatments, lifestyle costs, or whatever else you need.
Cancer-Only Policies
Cancer-only policies pay a lump sum on cancer diagnosis. They cost about half what CI costs because they cover a narrower risk. They make sense for people with very strong family cancer history (multiple first-degree relatives) or BRCA1/BRCA2 carriers.
Downside: if you have a heart attack or stroke, you get nothing. Lifetime cancer risk is about 40% (NCI); lifetime heart disease risk is about 50%; lifetime stroke risk about 25%. Cancer-only insurance only addresses one of these.

Why Critical Illness Usually Beats Cancer-Only
On the same coverage amount ($50K), CI costs $35-55/month vs cancer-only $20-30/month at age 45. The $15-25/month extra buys coverage for heart attack, stroke, and major organ failure — risks more common than cancer for many people.
Unless you have specific cancer-focused risk factors (BRCA, family history, prior cancer), the broader CI policy is the better risk-adjusted value.
When You Don't Need Either
If you have: 3-6 months emergency fund, comprehensive health insurance with out-of-pocket max under $10K, long-term disability insurance, and no dependents — you may not need CI or cancer insurance at all.
The biggest financial risk of a critical illness is lost income, not medical bills (which health insurance covers up to OOP max). Disability insurance addresses lost income better than CI. See our disability insurance needs calculator.
