This was tested in people. That is the most reliable kind of research we share.
This kind of focused radiation is already used in patients today.
The short version
Focused radiation kept most of these deep brain tumors from growing.
What was studied. Doctors looked back at records from one hospital, from 2002 to 2024. They found 47 patients with 49 spots of cancer that had spread to the thalamus, a deep part of the brain. All the spots were treated with focused radiation.
What they found. At 12 months, 82.5% of the treated spots were still under control. At 24 months, 78% were still under control. Higher radiation doses were linked to less tumor regrowth.
What this means, and what it doesn't
What it could mean: Focused radiation may be one option for tumors in this deep part of the brain. It does not need surgery. Your own doctor can tell you if it fits your case.
What it doesn't mean: This is not a cure. The team only looked back at old records from one hospital. They did not compare this to any other treatment. It does not promise how long any one person will live. What happened to this group may not happen for you.
