This was done in animals, not people. Most findings at this stage never become treatments.
This was only done in dogs.
The short version
This study was in dogs, not people. It tested a simple blood check.
What was studied. Doctors looked back at records for seventy pet dogs. All had a hormone problem caused by a tumor on a small gland under the brain. The team compared a blood check of two hormones with the size of each dog's tumor.
What they found. In this group, 30 dogs had small tumors and 40 had larger ones. Dogs with larger tumors had higher results on the blood check. The result also rose as tumor size rose. But the check could not sort small from large tumors in every dog.
What this means, and what it doesn't
What it could mean: Nothing here changes care for people with brain tumors. For dogs, it hints that a blood check might give a vet a rough idea of tumor size when a scan is not an option.
What it doesn't mean: This does not mean there is a new test for people. It was done in dogs only, and it looked back at old records. It is not a treatment and not a cure. It is a long way from anything you would see at your own clinic.
