New Testing Approach using Genomic Technology and Machine Learning to Detect Cancer Signals in Blood
Dr. Josh Offman, president of Grail, explains a new testing approach that utilizes genomic technology and machine learning to detect cancer signals in the blood. This approach goes beyond current screening methods and can identify over 50 types of cancers. The test analyzes methylation patterns on DNA, which are specific to cancer cells, and employs a machine learning classifier to accurately detect the presence of cancer. The test has a low false-positive rate and a high positive predictive value, making it a game-changer in early cancer detection.
