This was tested in people. That is the most reliable kind of research we share.
An early computer tool tested on past scans, not yet proven or used in care.
The short version
Researchers built an early computer tool that guesses details about a tumor from brain scans, but it is not ready for patients.
What was studied. Researchers looked at 241 brain MRI scans from 142 people whose breast cancer had spread to the brain. They trained a computer program to guess three tumor markers from the scans alone, without taking a sample from the brain.
What they found. The program did better than chance, but not by much. It did best on one marker, called PR, and worst on another, called ER. The authors say it was less accurate than other computer tools that others have already made.
What this means, and what it doesn't
What it could mean: Tumors that spread to the brain can have different markers than the first tumor in the breast. These markers help doctors choose treatment. Taking a sample from the brain is rarely practical. Someday, a tool like this might help doctors learn about these markers from a scan instead.
What it doesn't mean: This does not mean a scan can replace a tumor sample today. It was an early test using past scans, and the authors call the results preliminary. It has not been shown to help patients. It still needs testing in larger groups at many hospitals. It is not a new treatment and not a cure.
