GE Healthcare’s decision to move potentially hundreds of jobs to Massachusetts — and the already-existing cluster of major life sciences companies — could help reduce health care costs and create greater access to cutting-edge medical technology in the Bay State, an expert told the Herald.

“Having these companies close by where research staff are studying these diseases, it probably means our hospitals remain on the cutting edge of medicine,” said Barry Bluestone of Northeastern University. “So when a breakthrough comes and it’s FDA approved, the first who get to use it are probably patients in the Boston area. We probably do benefit — by being the first adopters of new medical breakthroughs.”
