This was tested in people. That is the most reliable kind of research we share.
This was computer planning work only, not a treatment given to patients.
The short version
Researchers tested computer plans that aim radiation at hidden tumor cells.
What was studied. Scientists used a computer model to guess how far glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary cells spread. They used brain scans from three patients with different levels of difficulty. They then built radiation dose plans on the computer.
What they found. The plans covered the tumor and still spared healthy organs nearby. The team said these plans were acceptable for clinic use. One score that checks how well a plan matches the goal averaged 95% for the main tumor area. That score got worse as the target area got bigger.
What this means, and what it doesn't
What it could mean: Radiation might one day be aimed wider than a scan shows. The goal is to reach tumor cells that scans cannot pick up. Right now this is only a plan built and checked on a computer.
What it doesn't mean: This does not mean a new treatment is ready for you. It was computer planning work, not a trial in patients. It used only three cases. It is not a promise of a cure. Much more study is needed before this could change care.
