Fewer than half the people found to have colorectal cancer are diagnosed at an early stage, when treatment is most effective. New therapies can reduce tumor size and prolong life, but they can also be costly and not work as intended. The results and interpretations from our laboratories provide clinically actionable results to guide treatment selection, ensuring every patient receives the medication most appropriate for care. In addition to guiding treatment, our testing also assesses risk for developing hereditary cancer syndrome.
