8. New blood-based test could detect all lung cancer types
Exact Sciences and the Mayo Clinic recently collaborated on a blood-based lung cancer test that researchers say has shown high accuracy for detecting all stages of lung cancer.
The blood test developed by Exact Sciences was tested on a group of 398 patients. Of those patients, 311 were controls and the remaining 87 had cancer. The study showed that the biomarkers in plasma were highly accurate for determining if a patient had any type at any stage of lung cancer. Four novel methylated DNA markers had a sensitivity of 91-96% at a specificity of 90-94%.
