Investigations Find No Environmental Cause for Nurses' Brain Tumors at Massachusetts Hospital

Multiple investigations by the Massachusetts Department of Public Health, Mass General Brigham Occupational Health Service, and OSHA have found no environmental link between working conditions at Newton-Wellesley Hospital and the cluster of noncancerous brain tumors diagnosed among seven current and former maternity ward nurses. These reports confirmed that all radiation levels on the relevant hospital floor were within regulatory limits, and air and water testing revealed no hazards. Hospital leadership emphasized the facility's safety and their commitment to staff well-being, noting that most brain tumors develop without identifiable environmental risk factors. Despite these findings, some affected nurses remain concerned and are calling for an independent third-party review, questioning the thoroughness and impartiality of the investigations conducted so far. The hospital has indicated willingness to consider further review to reassure staff. The Department of Public Health also invited additional staff to come forward if they have concerns.
