This was done on cells in a lab, not in people. It is a very early step.
This was only tested in a lab on samples, not in patients.
The short version
Scientists built a small, cheap device that can spot glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary cells in a liquid sample.
What was studied. Researchers built a sensor that pulls liquid in by itself, with no pump. They tested it on glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary cells in liquid and on blood serum from healthy people and patients.
What they found. The sensor's reading changed as the number of tumor cells in the liquid went up. It also gave different readings for different kinds of glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary cells. It showed some difference between healthy and patient serum. But the authors say it did not tell the serum samples apart well.
What this means, and what it doesn't
What it could mean: For now this means nothing changes in your care. If it keeps working, it might one day become a fast, low cost lab test. The sample needs little prep, and the cells are not destroyed.
What it doesn't mean: This is not a treatment, and it is not a cure. It does not help anyone feel better today. The work was done in a lab on samples, not in patients. The device has not been proven as a test a doctor can order. Much more testing is needed first.
