Tests of an AI-based Lymph Node Assistant achieved 99% accuracy in the detection of metastatic breast cancer, according to researchers at Google AI and the Naval Medical Center in San Diego. The system was able to identify a patient with cancer that had spread from her lymph nodes into other parts of her body. When the model was adjusted to find every tumour on every slide, it showed 69% sensitivity with no false positives and was unaffected by air bubbles or poor preparation. The system was not perfect, but performed better than a human pathologist in testing. Further work will look at whether the algorithm improves efficiency and accuracy.
