Stress may help brain tumors grow
Original title: Stress lends a helping hand to glioma.
How far along is this research?
This is a news item, not a research finding.
This is early lab science, not a treatment a patient can get.
The short version
Stress may push certain immune cells to help a brain tumor.
What was studied. This report looks at how stress affects the immune system around glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary, a type of brain tumor. It looks at immune cells called macrophages that gather at the tumor.
What they found. Stress sets off a link between the nerves and the immune system. That link pulls macrophages toward the glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary. Those cells make the area friendlier to the tumor.
What this means, and what it doesn't
What it could mean: It hints that stress may play some part in how these tumors grow. Care teams already offer help with stress. This work does not change your treatment today.
What it doesn't mean: This is early science, not a treatment you can get. It does not mean stress caused your tumor. It does not mean lowering stress will shrink a tumor. It is not a cure, and it is a long way from everyday care.
