Mystery in the USA: Five Nurses Diagnosed with Brain Tumors in Same Clinic

An investigation is underway in the **USA** after five nurses working in the same obstetrics clinic at a Boston hospital were diagnosed with **brain tumors**. The **Newton-Wellesley** hospital conducted an investigation, which began in December 2024, to identify potential environmental risk factors, such as **water**, **radiation levels**, and **air quality**, but found no correlation.
The nurses' labor union, the Massachusetts Nurses Association, is continuing its own investigations, as it believes the hospital's investigation was not thorough enough. It has collected 300 questionnaires from current and former employees and is evaluating them.
