Multi Cancer Early Detection Test

Revolutionizing cancer screening with a single, simple blood test.

Cancer is most treatable when detected early—but traditional screening methods only cover a few types of cancer, leaving many others to go undetected until they’ve advanced. The Multi-Cancer Early Detection Test by GRAIL changes this approach, offering an innovative way to screen for more than 50 different types of cancer from a single blood draw.

This groundbreaking test uses advanced genomic sequencing and machine learning technology to analyze tiny fragments of DNA—called cell-free DNA (cfDNA)—that are released into the bloodstream. By identifying specific patterns in these fragments, the test can detect potential cancer signals, often before symptoms appear.

This proactive screening tool represents a new era in preventive healthcare, helping you and your provider take action earlier and with greater precision. It sits within our Advanced Lab Testing offerings, offering a broader context of health diagnostics.

Why the GRAIL Test is Different

Most cancer screenings focus on one type of cancer at a time—like mammograms for breast cancer or colonoscopies for colorectal cancer. The Multi-Cancer Early Detection Test by GRAIL provides a much broader layer of protection, detecting signals for hard-to-screen cancers such as:

• Pancreatic cancer

• Ovarian cancer

• Esophageal cancer

• Liver and bile duct cancers

• Head and neck cancers

• And many others that currently lack standard screening protocols

By covering a wide spectrum of cancers, including those that often remain hidden until late stages, GRAIL’s test helps uncover potential risks at a point when treatment is far more effective.

Galleri can detect early-stage cancers before symptoms arise. Though still evolving, its high specificity aims to minimize false positives while helping pinpoint tissue-of-origin for positive findings.

Who Should Consider the Multi-Cancer Early Detection Test?

This test is designed for individuals who want to take a proactive approach to their health. It’s especially valuable for:

• Those with a family history of cancer, seeking earlier insight into their own risks

• Individuals at elevated risk due to age, lifestyle, or environmental exposures

• Patients undergoing comprehensive health assessments who want an added layer of cancer screening

• Anyone who wants to detect cancer activity early, even when there are no obvious symptoms

While it’s not a replacement for guideline-recommended screenings (like mammograms or colonoscopies), it serves as an additional tool to broaden your cancer detection strategy. It's intended as a supplementary tool—not a replacement—for guideline-recommended cancer screening.

How It Works

The process is simple:

1. A single blood draw is collected from your arm.

2. The sample is analyzed using genomic sequencing to evaluate cfDNA for abnormal patterns associated with cancer.

3. Machine learning algorithms interpret these patterns to determine if there are any concerning cancer signals present.

4. Results are shared with you and your provider, offering clear insight into potential next steps if any signals are detected.

This seamless process makes the test a convenient and powerful addition to your preventive healthcare plan.

Benefits of the GRAIL Multi-Cancer Test

• Broad Coverage: Detects potential signals for over 50 types of cancer, including many that have no standard screening test.

• Early Detection: Helps identify cancer activity at earlier, more treatable stages, potentially improving outcomes.

• Peace of Mind: Provides reassurance if no signals are found, while giving you the information needed for timely medical follow-up if needed.

• Empowerment: Enables you and your healthcare provider to take informed, proactive action for long-term wellness.

With this test, you gain a critical layer of insight into your health—one that could be truly life-saving.

A Smarter Approach to Cancer Prevention

Traditional screenings save lives, but they only cover a small percentage of cancers. By adding the Multi-Cancer Early Detection Test by GRAIL to your preventive care plan, you’re expanding your ability to catch cancer earlier, when interventions are far more effective and outcomes more favorable.
