This was done in animals, not people. Most findings at this stage never become treatments.
This was only done on cells in a dish and in mice.
The short version
Scientists built a lab test that picked out tumor signs in mouse blood.
What was studied. Researchers tested a new lab tool that shines light on tiny bubbles shed by cells. They used bubbles from lung cancer cells and blood from mice with a brain tumor called glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary.
What they found. The tool told the two kinds of lung cancer cell bubbles apart with 98% accuracy. It told blood from mice with glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary apart from healthy mouse blood with 97% accuracy. It worked better than older versions that used only one color of light.
What this means, and what it doesn't
What it could mean: Someday this kind of tool might lead to a blood test that helps find tumors. Right now it is only a lab method, not something a doctor can order.
What it doesn't mean: This does not mean there is a new test or treatment for people. The work was done on cells in a dish and in mice. The authors say it still needs testing on human blood samples. This is early lab work, far from everyday care, and it is not a cure.
