5 nurses who work on the same floor at Massachusetts hospital have brain tumors

Main Idea: Mass General Brigham Newton-Wellesley Hospital is investigating after five nurses on the same maternity floor were found to have brain tumors, but the hospital says it found no clear environmental cause.

Key Points:

• The hospital said 11 employees from the fifth-floor maternity unit reported health concerns, including five brain tumors.
• All of the tumors were benign, and two were meningiomas, a common benign brain tumor.
• The hospital said it looked at possible causes such as masks, water, nearby X-rays, and chemotherapy treatment below the floor, and ruled them out.
• The Massachusetts Nurses Association says it will keep investigating and wants an independent scientific review.
