Researchers have developed an AI-powered blood test that can accurately detect over 50 different types of cancer and identify where in the body it resides.
Until now, doctors had to look for specific types of cancer individually, which was not practical, and many cases were being diagnosed much too late.
The test uses a machine learning algorithm to search for specific changes to DNA associated with cancer. It is able to detect 18% of stage I tumors, 43% of stage II, 81% of stage III and 93% of stage IV, and can pinpoint the tissue it is located in with 93% accuracy.
Obviously the main drawback to this breakthrough technology is the low detection rate for stage I cancers.
