- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This is a report on three patients, not a test of a new treatment.
The short version
In three patients, a brain growth turned out to be thyroid cancer that had spread.
What was studied. Doctors in Karachi, Pakistan report on three patients with a growth in the head. Each had swelling on the scalp and headaches that pain pills did not help. Two also had seizures.
What they found. Scans first made the doctors think of a meningioma, a kind of brain tumor. All three had surgery to take the growth out. Tests on the tissue showed it was medullary thyroid cancer that had spread, not a meningioma. After surgery, the headaches and seizures went away, and the patients stayed stable.
What this means, and what it doesn't
What it could mean: A growth in the head does not always start in the brain. It can come from a cancer that began in another part of the body. Doctors may want to check the rest of the body to find the source.
What it doesn't mean: This is only a report on three patients. It is not a trial, and it does not test any new drug or treatment. The kind of spread shown here is very rare. This is not a cure and it is not a promise of one.
