New DNA sequencing technology at the Brigham and Women's Hospital (BWH) has identified several new unique genetic mutations in mesothelioma cancer cells that were previously unidentified. The findings serve as promising evidence that the improved sensitivity and effectiveness of DNA sequencing technology is providing more pertinent and rapid results in relation to cancer gene profiling.
