This was tested in people. That is the most reliable kind of research we share.
This is a report on one patient who was watched over time, not a tested treatment.
The short version
Doctors found a rare tumor in a woman's pelvis, and it did not grow over a year.
What was studied. This is a report about one patient. She was a 32 year old woman with no symptoms. A 38 mm lump near her right sacroiliac joint was found by chance on a CT scan.
What they found. Scans showed a smooth, well defined lump on the bone near the joint. It had not eaten into the bone around it. Doctors took a small sample with a needle. Lab tests showed it was a meningioma, grade 1, which is the slowest growing kind. One year later, scans showed no change at all, so doctors chose to watch it instead of treating it.
What this means, and what it doesn't
What it could mean: Meningiomas usually grow on the coverings of the brain or spine. This report shows one can also show up on its own in the pelvis. For a patient, it is a reminder that a lump like this can be slow growing. Watching it with scans can be a reasonable choice when there are no symptoms.
What it doesn't mean: This is a report about one person, not a study of a treatment. Nothing here was tested against anything else. It does not tell you what will happen in your own case, and it is not a cure or a new therapy. Only your own care team can say what your scans mean for you.
