- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This kind of scan is used in hospitals today, but here it was only one patient's story.
The short version
A special brain scan told doctors what a rare brain mass was, without surgery.
What was studied. Doctors report on one woman, age 53. Her breast cancer had come back and spread. A brain scan found a single mass near the back of her brain, close to the ear.
What they found. The mass was 28 x 24 mm. A scan called MR spectroscopy looks at chemicals inside tissue. The pattern it showed pointed to cancer that had spread, so she did not need a biopsy. She had focused radiation, 30 Gy in 5 sessions, and the mass was much smaller five months later.
What this means, and what it doesn't
What it could mean: Most masses in this spot are not cancer that has spread. A chemical scan may help doctors tell what a mass is. For some people, that could mean skipping a biopsy.
What it doesn't mean: This is one person's story, not a study of many people. One good result does not prove the scan works for everyone. It is not a new treatment, and it is not a cure. Your own care team still decides if a biopsy is needed.
