This was done on cells in a lab, not in people. It is a very early step.
This was only tested on tissue samples with a lab machine, not in real surgery.
The short version
Researchers built a scanner that checks brain tumor tissue in minutes instead of days.
What was studied. Scientists tested a new tissue scanner that uses terahertz light and a computer program. They used frozen tissue from 53 patients, covering 59 tissue samples and 590 spectra.
What they found. The computer program sorted the tissue into five groups that matter for treatment. It got the right group 97.48% of the time across five test runs. One scan took about 8 s, and a sample could be made ready in about 3 min.
What this means, and what it doesn't
What it could mean: Surgeons need to know a tumor's molecular type to decide how much to remove. Today that test is slow. A fast bench test like this could one day give answers during the operation. It would not treat the tumor. It would only help guide the surgery.
What it doesn't mean: This is not a treatment and not a cure. It is early lab work, not care you can ask for. The tissue was tested on a machine in a lab after removal, not inside a patient. The tool has not been approved or proven in real operations. Much more testing is needed before any hospital could use it.
