This was tested in people. That is the most reliable kind of research we share.
This is one patient's case, not a test of a new treatment.
The short version
A man's brain tumor grew very large before doctors found it.
What was studied. This is a report about one patient. He was a 54-year-old man with a history of substance abuse.
What they found. For several months he acted in ways that were not like him. His concerns were brushed off at first. Doctors then found a large glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary, a fast-growing tumor, on the left side of his brain. The report says a tumor this size still cannot be cured, and that it is a rare finding in Western countries.
What this means, and what it doesn't
What it could mean: It shows why a big change in behavior is worth checking. If someone acts very differently for months, a doctor should look for a cause. It also shows how easy it is for a person's symptoms to be dismissed.
What it doesn't mean: This is one person's story, not a study of a treatment. It does not test any new drug or therapy. It does not change the care a doctor gives today, and it is not a promise of a cure.
