- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This study looked at scans of people, but it does not test any treatment.
The short version
Researchers looked at brain scans to see how a small part of the brain changes in people with brain tumors.
What was studied. Researchers looked back at brain scans from 811 people with brain tumors and 744 people without them. The tumor group had 674 people with gliomas and 137 with a related kind of tumor. A computer program measured the size of a small part inside the brain called the choroid plexus.
What they found. This part was larger in people whose tumors were in the lower back part of the brain. How fast-growing or serious the tumor was did not seem to change its size. It was also larger with certain tumor types, and a certain gene change was linked to a smaller size, but that finding needs more study.
What this means, and what it doesn't
What it could mean: Where a tumor sits and what type it is may be linked to changes in this part of the brain. This could help researchers understand brain tumors better over time.
What it doesn't mean: This study only looked at scans. It does not test a treatment. It does not change how doctors care for patients today. It is not a cure, and the gene finding still needs to be checked.
