Six healthcare employees on the same floor at a Massachusetts hospital report developing brain tumors. | Massachusetts

The number of staff members at a Boston-area hospital who have developed brain tumors while working on the same floor has risen to at least six, according to the facility’s leadership. The newest reported tumor is benign, as are five previously documented cases. Investigators have not found evidence of environmental risks at the hospital, but their work continues. A labor union representing nurses at the hospital is calling for answers, and has expressed concerns over the hospital’s testing methods and limited consultations with nurses. The hospital maintains that the cases may be a coincidence, and has assured the public that no environmental risks have been identified.
