This was done on cells in a lab, not in people. It is a very early step.
This is an early computer method tested on blood samples, not a test doctors can use.
The short version
Researchers built a computer program that fills in a costly blood scan using a cheaper one.
What was studied. Researchers used blood from five groups: healthy people and people 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, kidney, lung, or food pipe cancer. Glioma is a type of brain tumor. They built a computer program to make one kind of light scan of blood, called Raman, from a cheaper, easier scan.
What they found. The scans the program made looked very close to the real Raman scans. The program did better than the other computer methods it was compared with. Adding the made-up scans also helped a computer tell the cancer groups apart better.
What this means, and what it doesn't
What it could mean: Someday, this might help make blood tests for cancer cheaper and easier to run. Raman machines cost a lot, so a program that fills in the scan could help more clinics use this kind of test.
What it doesn't mean: This is not a test you can get. It is an early computer study done on blood samples. It does not find cancer in patients yet, and it does not treat cancer. It is not a cure. A lot more testing is needed before doctors could ever use it.
