Could Your Brain Microbiome Be Fuelling Cancer Growth?

We used to think the brain was sterile—but research now shows the brain has its own microbiome, just like the gut!

And it’s not just about neurodegenerative diseases like Alzheimer’s; this hidden community of microbes might be fueling brain metastasis too. 🌿🔬

The brain microbiome affects the local environment, potentially promoting inflammation through cells like microglia, and disrupting the blood-brain barrier. This creates pathways for cancer to invade the brain—much like how gut dysbiosis can lead to leaky gut. 🌱🧠

Here are some of the cancers affected by their unique microbiomes:

* Colorectal Cancer

* Pancreatic Cancer

* Breast Cancer

* Lung Cancer
