This looks across many earlier studies rather than running a new one.
This is a summary of where the science is heading, not a new treatment.
The short version
Researchers are finding that nerves can feed tumor growth, including in brain tumors.
What was studied. This is a review paper, not a new study. The authors pulled together past research on how nerves and brain activity affect cancer cells.
What they found. Gliomas, a type of brain tumor, form real connections with nerve cells. The tumor cells tap into the brain's own signals to keep growing. The authors report similar links in brain metastases and in small cell lung cancer, breast, pancreatic, and prostate cancer. They also describe how these nerve signals can help tumors resist chemotherapy and other drugs.
What this means, and what it doesn't
What it could mean: The nervous system may become a new target for cancer treatment. Someday, drugs might block the signals that tumors use to grow. This does not change any care a patient can get today.
What it doesn't mean: This is a review of earlier work, not a new result or a trial in people. No treatment was tested here. The authors warn that blocking nerve signals could harm the brain, so safety has to be worked out first. This is not a promise of a cure, and it is far from everyday care.
