Essay: California Can Close Its Colorectal Cancer Gap

August 13, 2026

Colorectal cancer reveals significant racial health disparities in California, where Black residents face both higher incidence rates and a 43% higher mortality rate compared to White Californians. While the state possesses excellent cancer infrastructure, gaps persist throughout the entire care continuum—from prevention and screening through treatment and post-treatment surveillance. Kaiser Permanente Northern California demonstrated that organized interventions, including mailed stool tests and systematic follow-up tracking, can virtually eliminate racial mortality gaps, raising screening rates among Black members from 40% to 80% between 2009 and 2019.

Who is affected

Black Californians (experiencing higher colorectal cancer incidence and mortality rates)
White Californians (used as comparison group)
Patients in Medi-Cal, county health systems, and community clinics
Kaiser Permanente Northern California members (Black members specifically mentioned as benefiting from organized screening programs)
Cancer survivors requiring post-treatment surveillance
Community organizations, churches, and public hospitals involved in outreach efforts

What action is being taken

No explicit ongoing actions are described in the article. The article discusses past interventions (such as Kaiser Permanente Northern California's program from 2009-2019) and proposes future actions, but does not explicitly state what is currently being implemented.

Why it matters

This issue matters because the racial disparities in colorectal cancer outcomes are largely preventable rather than biologically inevitable. The 43% difference in mortality rates between Black and White Californians represents lives that could be saved through equitable access to screening, timely diagnosis, and guideline-concordant treatment. Colorectal cancer is one of the few cancers that can actually be prevented through screening (by removing precancerous polyps), making missed screening opportunities particularly consequential. The Kaiser Permanente success story demonstrates that organized, systematic approaches can eliminate racial mortality gaps, proving these disparities stem from healthcare system failures rather than unchangeable factors.

What's next

Mailed screening outreach, patient navigation, and guaranteed follow-up colonoscopy should become standard across Medi-Cal, county health systems, and community clinics
Health systems should publicly report screening completion, time from positive stool test to colonoscopy, time from diagnosis to treatment, receipt of guideline-concordant therapy, and completion of post-treatment surveillance—all stratified by race, insurance, and neighborhood
Address practical barriers including transportation, paid time off, bowel-preparation costs, childcare, and distrust
Community organizations, churches, clinicians, and public hospitals should help design outreach from the beginning
Cancer survivors should leave treatment with clear surveillance plans, navigation support, and sustained reminders
