This was tested in people. That is the most reliable kind of research we share.
This looked back at past surgeries in people, and it still needs a planned study.
The short version
A glowing dye helped surgeons see tumor tissue that was left behind.
What was studied. Doctors looked back at 265 meningioma surgeries in 244 patients. Each surgery used a drug called 5-ALA: A medicine you are given before some brain operations. The tumor soaks it up. Under a special light the tumor then glows, so the surgeon can see where it stops and healthy brain starts. See the glossary, which makes tumor tissue glow during the operation.
What they found. The tumor glowed in 254 of 265 cases. The tumor bed had no glow left in 216 of 254 cases. A glowing lump was still left in 38 of 254 cases.
What this means, and what it doesn't
What it could mean: The glow can show a surgeon tissue that is easy to miss. It also gives a simple way to write down what was left behind. This dye is already used in some brain surgeries.
What it doesn't mean: This is not a new treatment, and it is not a cure. The team only looked back at past surgeries at one hospital. They did not test whether the glow helps people live longer or keeps the tumor from coming back. The authors say the idea still needs to be tested in a planned study before it becomes normal care.
