How Does Galleri Work?
Galleri is a simple blood test that analyzes circulating cell-free DNA (cfDNA) fragments in the blood. These fragments, shed by tumors, can be indicative of various types of cancer. By examining the genetic makeup of these fragments, the test can identify potential cancer signals.
What Cancers Can Galleri Detect?
Galleri is designed to detect a wide range of cancers, including those that are difficult to detect through traditional screening methods. While the specific cancers that can be detected may vary, the test has shown promise in identifying cancers of the lung, breast, colon, rectum, esophagus, stomach, liver, pancreas, kidney, ovary, uterus, cervix, and prostate.
Early Detection and Improved Outcomes
Early detection is crucial in cancer treatment. By identifying cancer at an early stage, when it is often more treatable, Galleri can significantly improve patient outcomes.
Limitations and Considerations
It’s important to note that Galleri is not a definitive diagnostic test. A positive result from the Galleri test may indicate the presence of cancer, but further diagnostic tests, such as imaging or biopsies, are necessary to confirm the diagnosis and determine the exact type and location of the cancer.
The Future of Cancer Detection
The development of Galleri represents a significant step forward in cancer detection. As technology continues to advance, it is likely that blood-based cancer tests will become increasingly sophisticated and accurate. By enabling early detection and intervention, these tests have the potential to save countless lives.
