Story summary

A study by Mass General Brigham indicates adults with moderate-to-severe traumatic brain injury (TBI) face a higher risk of malignant brain tumors.
In 3-5 years post-injury, 0.6% of TBI patients developed tumors, versus 0.4% in controls.
No increased risk was found for mild TBIs, such as concussions.
The findings highlight the importance of long-term monitoring for TBI patients.
