This was tested in people. That is the most reliable kind of research we share.
This is a report on one patient, not a new treatment.
The short version
A spot that lit up on a scan turned out to be a harmless growth, not cancer.
What was studied. Doctors report on one man, age 53, who had smoked for a long time. He came in with ear pain and ringing in his ear. A mass taken out of his brain showed cancer that had spread there.
What they found. A PET scan showed a spot in the upper part of his left lung. It also showed a small spot in a spit gland near his ear. Both spots lit up on the scan. A test of the lung spot showed lung cancer. A test of the ear spot showed a Warthin tumour, which is a growth that is not cancer.
What this means, and what it doesn't
What it could mean: A bright spot on a scan does not always mean cancer has spread. Some harmless growths light up the same way. This kind of growth is closely tied to smoking. Doctors may take a sample of a spot before they call it cancer.
What it doesn't mean: This is a report about one person, not a study. It does not test any new treatment. It is not a cure and it does not change care on its own. It also does not mean a bright spot is safe to ignore. Only your own tests can show what a spot is.
