This was tested in people. That is the most reliable kind of research we share.
Doctors only looked back at scans and tissue from past patients, and no treatment was tested.
The short version
Brain tumors with more of a protein called B7-H3 looked bigger on MRI scans.
What was studied. Doctors looked back at records for 99 adults with brain tumors called gliomas. All had surgery between 2013 and 2021. Their tumor tissue was tested for a protein called B7-H3, and their MRI scans were measured.
What they found. Tumors with more B7-H3 were larger on the MRI scans. They also had more swelling in the brain around the tumor. The link held even after doctors accounted for age, sex, tumor grade, and another tumor marker. But B7-H3 did not track with a score that compares swelling to tumor size.
What this means, and what it doesn't
What it could mean: This protein may be a sign of how much tumor and swelling show up on a scan. That is useful for doctors trying to understand the disease. It does not change how brain tumors are treated today.
What it doesn't mean: This does not mean B7-H3 is a treatment or a cure. No drug was tested here. The doctors only looked back at scans and tissue that already existed. It also does not prove the protein causes the swelling, only that the two went together. This is early lab and imaging work, far from anything a patient can ask for.
