This was done on cells in a lab, not in people. It is a very early step.
This was only done on cells and a few tissue samples in the lab.
The short version
Researchers tested a light based tool that can tell brain tumor cells from normal brain cells in the lab.
What was studied. Researchers shined a special light on three glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary cell lines and one normal brain cell line. They then checked tissue from three patients with glioblastoma and one patient with a severe head injury.
What they found. The light readings told the four cell lines apart. A computer program found clear differences between the normal brain cells and the three glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary cell lines. The same differences showed up in the patient tissue samples.
What this means, and what it doesn't
What it could mean: Surgery works better when the whole tumor can be taken out. But it is hard to see where a tumor ends during surgery. A tool like this might one day help surgeons see that edge. This study is an early step toward that.
What it doesn't mean: This does not mean a new test is ready for the operating room. The work was done on cells in a dish and on a small number of tissue samples. The tool was not used on people during surgery. It does not treat the tumor, and it is not a cure.
