This was done in animals, not people. Most findings at this stage never become treatments.
This was only done in mice.
The short version
In mice, a brain tumor seemed to change how organs across the body signal each other, not just the brain.
What was studied. Researchers scanned the whole bodies of mice using a type of PET scan that picks up a marker linked to immune cells. They compared 18 mice without a tumor to 20 mice with an early stage glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary and 29 mice with a late stage glioblastoma.
What they found. Mice with late stage tumors had a stronger signal in the tumor area. The signal in other single organs did not change in a meaningful way. But the way organs signaled together, including the lungs and healthy parts of the brain, was disrupted in both early and late stage mice. A second scan tracer in 53 more scans showed the same pattern, and these whole body patterns were linked to the stage of the tumor and to how long the mice lived.
What this means, and what it doesn't
What it could mean: This hints that a brain tumor may affect the immune system across the whole body, not only in the head. If that holds up, scans like this might one day help doctors track what a tumor is doing. Right now it is a research idea.
What it doesn't mean: This is not a treatment, and it is not a cure. The work was done in mice, not in people. Mice and people often respond differently. Nothing here changes the care you get today, and it does not mean a new scan or test is coming soon.
