This looks across many earlier studies rather than running a new one.
This looks back at a few rare cases and is not a treatment.
The short version
In a few rare cases, a brain tumor in a baby went away on its own.
What was studied. Doctors searched for past reports of babies born with brain tumors that went away on their own. They found six reports and also shared one new case, a baby whose tumor went away at 3 months old.
What they found. The babies had different signs, and one newborn had no signs at all. The tumors were in different parts of the brain, and some were fast-growing types. The tumors went away fully between 3 and 33 months of age.
What this means, and what it doesn't
What it could mean: It shows that, very rarely, a brain tumor in a baby can go away by itself. Doctors still do not fully understand why this happens.
What it doesn't mean: This does not mean a baby's brain tumor will go away without care. It was very rare and seen in only a handful of reported cases. This study looks back at past cases. It is not a new treatment and it is not a cure. Families should keep following their care team's advice.
