Watson for Genomics uses IBM's Watson cognitive computing system to help personalize cancer care. It analyzes genomic sequencing data and clinical records to provide treatment suggestions and clinical trial matches for patients in minutes, compared to weeks for traditional approaches. Researchers are finalizing the algorithm and testing it in clinical trials. Watson draws from a large corpus of medical literature and patient data to understand questions, generate hypotheses, and provide evidence to support its answers. It could help reduce health professionals' workload and improve access to care, though challenges remain in developing the algorithm and acquiring sufficient data sets.
