This was tested in people. That is the most reliable kind of research we share.
This is a small report on three girls who were already treated, not a new treatment.
The short version
Three girls showed early puberty signs that came from a brain tumor.
What was studied. Doctors looked back at the records of three girls. Each girl had a germ cell tumor in the brain. The doctors checked which signs showed up first.
What they found. All three girls were very thirsty and peed a lot first. Tests found a high hormone level in their blood and spinal fluid. After chemo and radiation, the hormone levels dropped to normal and the tumors got smaller.
What this means, and what it doesn't
What it could mean: Early puberty signs can point to a problem in the brain. The doctors say a simple blood test and a brain scan can help find the cause. Found early, treatment can start sooner.
What it doesn't mean: This is not a new treatment, and it is not a promise of a cure. It is a report on just three girls. A report this small cannot show how often this happens. Most children with early puberty do not have a brain tumor. Ask your doctor about any new signs.
