Sun Life U.S. Expands Cancer Second-Opinion Service to Disability, Critical Illness Claims
Event summary
- Sun Life U.S. will now proactively offer Expert Cancer Review (ECR) services when members file cancer-related disability or critical illness claims, expanding access beyond stop-loss policies.
- 41% of second opinions facilitated by Sun Life from 2024–2025 resulted in changes to diagnosis or treatment plans.
- Average annual cost of cancer claims ranges from $235,000 (solid cancers) to over $300,000 (blood cancers), per Sun Life's 2025 High Cost Claims Report.
- ECR is facilitated through Sun Life Health Navigator, which provides personal health advisors for care coordination.
The big picture
Sun Life's move aligns with rising cancer diagnoses among working-age adults (under 50) and the growing need for integrated benefits that support both health and financial security. By embedding ECR earlier in the claims process, Sun Life aims to improve care coordination while managing high-cost claims—a strategic shift as cancer treatment costs continue to escalate. The expansion builds on Sun Life's broader push to integrate health and risk solutions, following last year's Health Navigator service launch.
