A cluster of nurses at Newton-Wellesley Hospital have reportedly been diagnosed with brain tumors, according to hospital officials who are assuring staff and patients that there’s “no environmental risk” at the facility.
But the Massachusetts Nurses Association says the hospital’s environmental testing was “not comprehensive,” as the union continues to investigate the situation.
The nurses diagnosed with brain tumors have worked in the maternal care labor/delivery unit on the hospital’s fifth floor.
As of earlier this week, 11 staff who worked at some point and for varying durations on the fifth floor had been interviewed by the Mass General Brigham Occupational Health Service.

Five cases were determined to be brain tumors of three different types — all of which were benign (non-cancerous). The only type of benign tumor that had more than one case was meningioma.
Six cases were determined to not be brain tumors, but rather other health concerns.
“Based on the results of the extensive and deliberate investigation… we want to reassure our dedicated team members and all of our patients that there is not an environmental risk at Newton-Wellesley Hospital,” Mass General Brigham wrote in its “Fifth Floor Work Environment FAQs” after a staff town hall about the situation.
“We take this very seriously; our top priority is providing high-quality care in a safe and healthy environment for our staff and patients,” Mass General Brigham added.
This situation at Newton-Wellesley Hospital was first reported by WBZ.

After hospital officials learned of the reported brain tumors, they conducted an investigation with the Department of Occupational Health and Safety, Newton-Wellesley Safety Officer, radiation and pharmaceutical safety offices, and external environmental consultants.
“Every staff member who came forward was given the opportunity to be interviewed by the Occupational Health and Safety team to evaluate each diagnosis in the context of their individual medical history and risk factors,” hospital officials said in a statement. “To evaluate for any possible environmental exposures in that area of the hospital, comprehensive environmental assessments following CDC guidelines began in December.
“The investigation found no environmental risks which could be linked to the development of a brain tumor,” the officials said, later adding, “Based on these results, we can confidently reassure our dedicated team members at Mass General Brigham/Newton-Wellesley Hospital and all our patients that there is no environmental risk at our facility. As always, the health and wellbeing of our staff, clinicians, and patients is our absolute top priority.”
Staff members have raised several concerns about this cluster of cases. The hospital addressed questions about whether brain tumor cases can be related to: wearing masks during the pandemic, the drinking water, use of x-rays, or the pharmacy on the floor below.
“There is no scientific evidence linking long-term mask use (including processing/re-wearing of masks) to the development of brain tumors,” reads the Fifth Floor Work Environment FAQs.

Water serving the hospital is tested regularly by the Massachusetts Water Resources Authority.
“Out of an abundance of caution, additional water samples from the tap and ice machines have been sent for additional testing by Triumvirate Environmental, an independent environmental testing firm,” reads the FAQs. “Those results should be available in the coming week.”
Hospital officials said they use appropriate x-ray safety techniques throughout the hospital.
“To make sure that there was not another, unknown, source of ionizing radiation on the Fifth Floor, radiation levels were surveyed across the Fifth Floor using Geiger counters,” the hospital wrote. “This did not find any abnormal/increased levels of ionizing radiation.”
The pharmacy located on the fourth floor processes chemotherapy medications.

“These are handled within an independently ventilated, closed system and with appropriate precautions and controls that have been validated as part of this investigation,” the hospital wrote. “The hoods used in the Fourth Floor pharmacy have been installed and tested to ensure that they are functioning properly and safely ventilating away from the building. This system was re-tested by Triumvirate Environmental, an independent environmental firm, as part of the investigation, and was found to be operating properly.”
The Massachusetts Nurses Association’s division of health and safety, consisting of occupational health nurses, is investigating the situation.
“We do not have a specific number (of nurses) we are releasing now because we are still verifying diagnoses via medical records. We do not have a specific cause as we are still investigating,” a spokesperson for the union said in a statement.
“We brought this to the hospital in December to urge an investigation by MGB,” the union spokesperson added. “We have been in communication with NWH nurses about this regularly and specifically with nurses who are self-reporting.”
The union spokesperson said the investigation is focused on the maternity unit, though they have reports from other areas as well.

“We are engaging with the hospital about their inquiry,” the union spokesperson said. “They only spoke to a small number of nurses and their environmental testing was not comprehensive. The hospital cannot make this issue go away by attempting to provide a predetermined conclusion.”
Up the road from Gillette Stadium, a town neighboring Foxboro is pressing for funding to meet public safety demands arising from the World Cup, with the first match just over a month away.
Walpole’s state delegation has written a letter to the state Office of Travel and Tourism requesting approval of the town’s request for nearly $200,000 to support “essential public safety personnel,” as officials expect “significant spillover impacts” from the premier soccer tournament.
As the Walpole/Foxboro town line on Route 1 is a handful of miles north of Gillette Stadium, officials are expecting increased traffic congestion and pedestrian activity to amount to “heightened public safety demands.”
“As outlined in the Town’s proposal,” the state delegation wrote in the letter it sent to the state last week, “Walpole will play a critical role in ensuring safe and efficient operations for both residents and visitors.”

“This funding will help close a critical gap and ensure that Walpole can safely support this internationally significant event,” the delegation added.
The state Office of Travel and Tourism confirmed to the Herald that it received the letter from state Reps. John H. Rogers, Paul McMurtry, Ted Philips and Marcus Vaughn and Sen. Mike Rush. The office said it will announce decisions in the coming weeks about round two of the $2 million grant program that supports municipal public safety needs tied to the World Cup.
The first round of the program, a $10 million competitive initiative, awarded funding earlier this year to 17 communities to support tournament-related events, including fan festivals, watch parties and regional activations.
This comes after the Foxboro Select Board battled the Boston Soccer 2026 nonprofit host committee and Kraft Sports & Entertainment, which operates Gillette Stadium, for months to ensure it received full funding to cover all security personnel and equipment.
In mid-March, the David vs. Goliath fight concluded, with Boston Soccer 2026 and the Krafts agreeing to cover Foxboro’s $7.8 million request.

Gillette, which will be rebranded as “Boston Stadium,” is set to host seven matches – five in the group stage and two knockout games – between June 13 and July 9. The World Cup is considered a SEAR 1 event, the highest risk level for public gatherings in the country.
“These matches will bring an excitement that this town has never seen,” Foxboro Police Chief Michael Grace said before the Select Board voted to grant an entertainment license for the matches to go on.

No other city in the country boasts more championships than Boston, giving Massachusetts a sporting pedigree unlike any other.
What’s unique about many of the state is that several of the stars from those championship-winning teams were Massachusetts natives.
Before they were winning the Stanley Cup, the Super Bowl, the NBA Finals, World Series or a gold medal, those athletes were high school standouts.

According to a study conducted by Niche, which accounts for survey feedback from students and parents—accounting for “reviews of athletics, number of state championships, student participation in athletics, and the number of sports offered at the school”—and data from the U.S. Department of Education, these are the top 25.
BOSTON (WHDH) – It was a powerful moment on Friday during the annual Law-Enforcement Memorial Ceremony at the State House, as the ceremony remembered those lost in the line of duty, including State Trooper Kevin Trainor.
Trainor was killed in a wrong-way crash this week. Trainor’s family was in attendance.
“We’re here today with the Trainor family as another tragedy and agonizing time in policing has found us,” Larry Calderone, Boston Police Union President, said.
The day brought a moment to pause and remember the 30-year-old who is being hailed a hero after he was struck and killed Wednesday morning on Route 1 in Lynnfield.

“We’ve lost a brother,” Massachusetts State Police Col. Geoffrey Noble said.
The fallen trooper’s fiancée spoke out for the first time since losing the love of her life. She posted to social media, “I am beyond proud of the amount of love you have been given by those who loved and cared about you shows us who you really were, a friend, a partner, a brother, a son, and a hero. You weren’t just a hero to me but a hero to all.”
