This was tested in people. That is the most reliable kind of research we share.
This is a report about one person's care, not a treatment you can get.
The short version
Doctors found lung cancer growing inside a man's brain tumor.
What was studied. This is a report about one person's care, not a study. An 80-year-old man who smoked had thinking problems that kept getting worse. A scan showed a fast growing mass on the covering of his brain.
What they found. A chest x-ray showed a spot in his chest. He did not get a chest CT scan or other cancer tests before brain surgery. After surgery, lab tests found lung cancer cells inside the brain tumor. He had radiation and chemotherapy, but the cancer spread to the lining around his brain. He died 15 months after surgery.
What this means, and what it doesn't
What it could mean: Sometimes one tumor can grow inside another tumor. For an older person who smoked, a chest scan before brain surgery may matter. It can change what doctors expect to find and how they plan the surgery.
What it doesn't mean: This is a report about one person's care, not a study. It does not test a new drug or a new treatment. It is not a cure and it does not promise anything. What happened to this man may not happen to anyone else.
