This was tested in people. That is the most reliable kind of research we share.
This was a look back at past patient records, not a test of a new treatment.
The short version
In this large look at past records, breast cancer rarely returned in the brain first, but those people did worse.
What was studied. Researchers went back through records from 7 breast cancer studies in Greece. The records covered 5,318 people who had treatment for early breast cancer.
What they found. 106 people (2%) had the cancer return in the brain first. Of those, 68 (64.2%) had it in the brain only. The risk was higher in triple negative breast cancer, and in people with four or more affected lymph nodes. People whose cancer came back in the brain lived a shorter time than people whose cancer came back elsewhere.
What this means, and what it doesn't
What it could mean: If you had triple negative breast cancer, or many affected lymph nodes, your risk of brain spread may be higher. You can ask your doctor what signs to watch for. Findings like these may help doctors decide who needs closer checks.
What it doesn't mean: This does not mean you will get brain spread. It was rare, seen in 2% of people here. This was a look back at old records, not a test of a new treatment. The care people got in those years was older than the care given today. Nothing here is a new treatment, and it is not a cure.
