Genomic alterations are changes that occur within the DNA of cancer cells. Some of these changes accelerate the growth of cancer. Some respond well to specific therapies. With a clear picture of the genomic alterations in your tumor, your doctor may be able to recommend a targeted therapy. In general, targeted therapies have fewer side effects than broad-based chemotherapy. They can also be more selective in stopping the spread of a cancer when other treatments have failed.

How do we achieve high specificity?
We search for tumor-DNA fragments among billions of cells
We digitally tag each DNA fragment and make millions of copies
Standard sequencing methods introduce errors and false positives
Our digital inference engine reduces these errors by 1000x
