Breakthrough Blood Test May Detect 50 Types of Cancers

The Mayo Clinic is developing a breakthrough blood test that can detect more than 50 different types of cancer across all stages.

The test, known as Galleri, was created in partnership with Menlo Park, California-based biotechnology and pharmaceutical company Grail.

Galleri looks for signals present in the blood stream that may be associated with cancer at the time of a blood draw.

The test uses next-generation sequencing and machine-learning algorithms to analyze methylation patterns of cell-free DNA (cfDNA) in the bloodstream, which can carry cancer-specific information. DNA methylation is a process used by cells to regulate gene expression. If a cancer signal is detected, Galleri will pinpoint where in the body the cancer is coming from to help health care providers determine the appropriate next steps for patient treatment.
