Galleri Cancer Test

If you are above the age of 21 and are interested in a comprehensive and proactive approach to maintaining your health and longevity, the Galleri Cancer Test is an excellent addition to your wellness journey especially if you have a higher risk level of certain types of cancer.

Yes, the Galleri Cancer Test is a transformative blood test redefining cancer detection. It scrutinizes a shared cancer signal within your blood for more than 50 types of cancers, including those evading standard screening. This heralds a new era in early cancer detection, facilitating swift intervention and significantly enhanced chances of successful treatment.

Every time you take the test, Galleri checks more than 100,000 DNA regions and over a million specific DNA sites to screen for a signal shared by multiple cancers. If a cancer signal is detected, results from the test predict the tissue type or organ associated with the cancer signal to help our healthcare provider determine the next steps.

Cancer risk increases for everyone as they age regardless of family history—only 5% to 10% of cancers are inherited. Age is the biggest risk factor for cancer. In fact, adults over age 50 are 13 times more likely to have cancer compared to people under the age of 50.

In a clinical study, Galleri detected a signal shared by over 50 types of cancer —including some fast-spreading and aggressive cancers responsible for approximately two-thirds of cancer deaths. Galleri is a cancer screening test, meaning it looks for cancer before symptoms appear. The Galleri test does not detect a signal for all cancers and not all cancers can be detected in the blood.

A “Cancer Signal Detected” result is expected in approximately 1% or 1 out of 100 Galleri tests in people over 50 years of age. In a recent clinical study, on average, 4 out of 10 people with a "Cancer Signal Detected" result received a cancer diagnosis with diagnostic testing, and 1 out of 200 people without cancer received a "Cancer Signal Detected" result.

No, the Galleri test is not a genetic risk assessment. A genetic risk assessment is a one-time-only measurement and assesses your future risk of developing cancer. The Galleri test looks for a signal associated with active cancer at the time of your blood draw. Genetic tests may look at DNA and assess lifelong risk for cancer but cannot detect if a person currently has cancer. Our goal is for Galleri to be an annual cancer screening test. By regularly using the Galleri test alongside recommended cancer screenings, you can increase your chance of finding cancer early.

If a cancer signal is detected, your healthcare provider will work with you to determine the next steps, which may include additional diagnostic testing to confirm the presence and location of cancer.

No, the Galleri test is not intended to replace routine cancer screenings like mammograms, colonoscopies, or pap smears. It is designed to complement these screenings and enhance early detection efforts.

The test is completed through a blood draw.

No, fasting is not required for this test.

Typically, it takes about 2-3 weeks from the time the sample is received by Grail to process and provide the test results.
