Biomarkers and Why Testing is Important

Once a person has been diagnosed with lung cancer, the “standard of care” practice is to test for a panel of biomarkers that could help to determine the treatment for that particular patient. Determining which biomarker is helping to drive the cancer allows the medical care team to determine the best and most effective treatment for that specific patient.
