The Math is Simple. Early Cancer Detection Matters.
The difference can be staggering. For certain cancers, five-year relative survival can exceed 90% when diagnosed at Stage I — but fall below 10% when diagnosed at Stage IV. That’s why Kevin Costner is helping us bring greater attention to the importance of finding cancer early. In our commercial, Kevin delivers a simple message with profound importance: finding cancer early matters.
BEYOND THE COMMERCIAL
Hear the Story Behind the Message
Kevin Costner sits down with David Dean Halbert, Founder, Chairman and CEO of Caris Life Sciences for a deeper conversation about early cancer detection, the importance of knowing early and why advancing cancer care starts with giving people better information earlier.
This video contains explicit language and may not be suitable for all audiences.
WHY EARLY DETECTION MATTERS
Early Cancer Detection can Change Everything.
Caris Detect — the only multi-cancer early detection blood test that analyzes the entire genome — has the ability to detect cancer signals that other tests may miss, even at early stages of disease development.
Powered by advanced Al technology trained on 50 billion molecular markers from more than 1 million real patient cases, Caris Detect is rooted in one of the largest oncological datasets of its kind. Through this depth and breadth of real-world evidence, Caris Detect identifies cancer earlier — and with industry-leading accuracy.
| Stage | Sensitivity |
|---|---|
| Stage I | 56.8% |
| Stage II | 67.7% |
| Stage I-II Combined | 60.3% |
| Stage III | 79.0% |
| Stage IV | 98.6% |
| Specificity | 99.2% in the asymptomatic screening population |
Stop waiting. Start knowing.
The sooner you know, the more power you have to take action. Caris Detect identifies cancer signals before symptoms even appear, when patients still have the greatest number of options — and the most time to act.

Understanding the
Caris Detect Report.
WHAT THIS MEANS
Results will be delivered directly to the patient and ordering healthcare provider. In the results report, Caris Detect recommends that patients review their results with their healthcare provider and develop a personalized cancer prevention and detection plan.
CARIS PROCESSES AND DELIVERS RESULTS
- Caris analyzes the sample using ultra-deep whole genome sequencing and advanced
artificial intelligence.
- Results will be delivered to the ordering provider and patient.
RESULTS REVIEWED WITH PROVIDERS
- The patient brings their results to their provider’s office for clinical interpretation and counsel.
- Provider guides the patient through next steps: specialist referral (if signal detected), monitoring plan (if atypical) or continued routine screening (if not detected).
- Providers can contact Caris Detect Clinical Care for additional support at (855) DETECT-0 (855-338-3280) or CarisDetect@CarisLS.com
No Cancer Signal Detected
WHAT THIS MEANS
No cancer signal was identified at the time of testing.
RECOMMENDED NEXT STEPS
- Continue all routine cancer screening tests recommended for your age, sex, personal medical history and family history, consistent with established guidelines such as those from the U.S. Preventive Services Task Force (USPSTF)1 and the American Cancer Society (ACS).2
- Maintain regular follow-up visits with your healthcare provider and promptly report any new, persistent or
unexplained symptoms or health changes.
- Consider repeating Caris Detect as part of your annual wellness and preventive screening plan in consultation with your healthcare provider.
Atypical Signal Detected
WHAT THIS MEANS
A minor abnormality was found in the blood sample that could be an early cancer signal.
RECOMMENDED NEXT STEPS
- Caris will provide complimentary repeat testing approximately 3 months after your initial Caris Detect result. The Caris Customer Support team will contact you directly to coordinate the blood draw and kit delivery.
- Continue all routine cancer screening tests recommended for your age, sex, personal medical history and family history, consistent with established guidelines such as those from the U.S. Preventive Services Task Force (USPSTF)1 and the American Cancer Society (ACS).2
- Maintain regular follow-up visits with your healthcare provider and promptly report any new, persistent or unexplained symptoms or health changes.
Cancer Signal Detected
WHAT THIS MEANS
Cancer signal was identified at the time of testing.
RECOMMENDED NEXT STEPS
- Review these results with your healthcare provider. Additional testing may be warranted to evaluate for the presence of cancer and could include laboratory studies, imaging and/or referral to a specialist.
- Based on the suspected tissue of origin information included in this report, your healthcare provider may recommend additional targeted screening or diagnostic evaluations.
- Continue all routine cancer screening tests recommended for your age, sex, personal medical history and family history, consistent with established guidelines such as those from the U.S. Preventive Services Task Force (USPSTF)1 and the American Cancer Society (ACS).2
What Happens if a Cancer Signal is Detected?
HOW IT WORKS
A Cancer Signal Detected result is not a cancer diagnosis. Additional diagnostic evaluation is required to determine whether cancer is present.
Blood Draw
A blood sample provides the molecular information analyzed by Caris Detect.
Detect
Caris Detect looks for molecular signals associated with cancer.
Identify Likely Origin
If a cancer signal is detected, potential Tissue of Origin sites are evaluated and ranked.
Guide Next Steps
The result can help your healthcare provider determine where to begin appropriate diagnostic evaluation.
Detection tells us there may be something to investigate. Tissue of Origin helps inform where to begin.
ACT ON YOUR RESULTS
Caris Detect does more than identify a cancer signal. When a Cancer Signal Detected result is returned, Tissue of Origin information can help identify where that signal may be coming from — giving you and your healthcare provider a more informed place to begin the next step.
Why Tissue of Origin Matters
More Informed Starting Point
Tissue of Origin information helps identify where a detected cancer signal may have originated, giving your healthcare provider a place to begin.
More Targeted Next Steps
Your healthcare provider can consider the Tissue of Origin information together with your health history and other clinical information when determining appropriate follow-up.
Information to Move Forward
A Cancer Signal Detected result can raise immediate questions. Tissue of Origin provides additional information designed to help guide what comes next.
Clinical Information About Tissue of Origin
FOR HEALTHCARE PROVIDERS
Caris Detect’s Tissue of Origin approach evaluates molecular features from plasma cell-free nucleic acids to generate and rank probabilities across potential tumor origins. These probabilities are intended to support an informed diagnostic pathway following a Cancer Signal Detected result.
Score
Caris Assure®-based GPSai® outputs a probability for each of 15 organ-system workups, per patient.
Rank
Order the suspected tissues of origin from most to least likely.
Turning Detection into Diagnostic Guidance
Target
A single anatomically focused scan for the top site provides answer for most patients.
Escalate
If initial evaluation is inconclusive, proceed to the next targeted scan or a bundled CT covering multiple candidate sites.
Caris Detect does not detect a signal for all cancers and not all cancers can be detected in the blood. False positive and false negative results may occur. Caris Detect is a companion screening test. It is not a replacement for routine cancer screenings recommended by your healthcare provider. Continue to get regular mammograms, colonoscopies and other routine screenings on your individual risk factors. Talk to your doctor about where Caris Detect fits in your personal health plan.
This test is a laboratory developed test (LDT) that has undergone Clinical Laboratory Improvement Amendments (CLIA) validation. This test is currently available on a cash-pay basis. No insurance coverage is currently available. FSA and HSA accounts may be used. A positive result is not a diagnosis. Results should be interpreted in conjunction with follow-up diagnostic testing and discussion with your healthcare provider.
