Only 5 types of cancer have recommended screening tests1
Screening tests look for cancer before symptoms appear. Currently, only 5 types of cancer—colorectal, lung (for those at risk), breast, cervical, and prostate—have recommended screening tests that can identify cancer earlier.1 Most other cancers, like pancreatic and ovarian, do not show symptoms early and are often diagnosed at a later stage.2
When cancer is diagnosed early before it has time to spread, the overall 5-year cancer-specific survival rate is 4 times higher than when cancer is diagnosed late.3
Many cancers are often found too late, when symptoms appear in later stages of cancer. The earlier that cancer is diagnosed, the greater the chance of successful treatment and survival.2 The earlier you know, the sooner you can act.
Get started with the Galleri® test
I am interested in learning more about the Galleri test
I am a healthcare provider interested in offering the Galleri test to my patients
I represent an employer interested in offering the Galleri test to my organization’s employees
I represent a health system interested in making the Galleri test available to my patient population
The Galleri test is recommended for use in adults with an elevated risk for cancer, such as those aged 50 or older. The Galleri test does not detect all cancers and should be used in addition to routine cancer screening tests recommended by a healthcare provider. Galleri is intended to detect cancer signals and predict where in the body the cancer signal is located. Use of Galleri is not recommended in individuals who are pregnant, 21 years old or younger, or undergoing active cancer treatment.
Results should be interpreted by a healthcare provider in the context of medical history, clinical signs and symptoms. A test result of “No Cancer Signal Detected” does not rule out cancer. A test result of “Cancer Signal Detected” requires confirmatory diagnostic evaluation by medically established procedures (e.g. imaging) to confirm cancer.
If cancer is not confirmed with further testing, it could mean that cancer is not present or testing was insufficient to detect cancer, including due to the cancer being located in a different part of the body. False-positive (a cancer signal detected when cancer is not present) and false-negative (a cancer signal not detected when cancer is present) test results do occur. Rx only.
GRAIL’s clinical laboratory is certified under the Clinical Laboratory Improvement Amendments of 1988 (CLIA) and accredited by the College of American Pathologists (CAP). The Galleri test was developed, and its performance characteristics were determined by GRAIL. The Galleri test has not been cleared or approved by the Food and Drug Administration. GRAIL’s clinical laboratory is regulated under CLIA to perform high-complexity testing. The Galleri test is intended for clinical purposes.
