This was tested in people. That is the most reliable kind of research we share.
This is a report about a patient, not a tested treatment.
The short version
A brain scan looked like cancer had spread, but it was not.
What was studied. Doctors describe the case of a patient. An 82-year-old woman had lung cancer removed. She had a brain scan after a fall.
What they found. The first scan looked like cancer had spread to the lining of her brain. But she felt well and her spinal fluid had no cancer cells. A second scan showed tiny bleeds, and a biopsy found swollen brain vessels.
What this means, and what it doesn't
What it could mean: A scan that looks like spread cancer is not always spread cancer. Doctors may repeat scans or run more tests first. In this case, the woman got better on her own. She did not need cancer treatment for her brain.
What it doesn't mean: This is a case report about one patient, not a study. It does not test any new treatment, and it is not a cure. It does not mean brain scan findings in cancer are usually harmless. Your own case may be different. Talk with your care team.
