This was tested in people. That is the most reliable kind of research we share.
This checked online videos, not a treatment for people.
The short version
Many popular short videos about brain tumor treatment leave out key facts.
What was studied. Researchers rated 200 popular Chinese-language videos about treating glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary, a type of brain tumor. The videos came from TikTok (103) and Bilibili (97), and were scored with rating tools for quality and trust.
What they found. TikTok videos were shorter, got more attention from users, and scored higher for quality than Bilibili videos. Videos posted by health professionals were more reliable. Only 30.0% of videos covered treatment based on tumor grade or gene type, and only 15.5% talked about how patients tend to do over time.
What this means, and what it doesn't
What it could mean: If you look up brain tumor care on short-video apps, take it with care. A video being popular does not mean it is right. Videos from doctors and other health workers were the more trustworthy ones. Bring anything you see to your own care team.
What it doesn't mean: This does not mean any of these videos can guide your care. The study only rated videos. It did not test a treatment, and it is not a cure or a promise of one. It also looked only at Chinese-language videos on two apps, so other apps may look different. Nothing here changes the care your doctor offers today.
