Five nurses from same unit in Boston hospital diagnosed with brain tumors

Newton-Wellesley hospital says it ruled out environmental risk as staff members diagnosed with benign growths

Five nurses working in the same unit at a Boston-area hospital have been diagnosed with non-cancerous brain tumors, prompting them and their labor union to search for answers while the medical facility contends it has ruled out an environmental risk for workers there.

According to a statement that Mass General Brigham's Newton-Wellesley hospital provided to NBC10 Boston, the five nurses either work or have previously worked in the facility's fifth-floor maternity unit.
