What Types of Brain Tumors Are Affected by the BBB?
Primary brain tumors, such as gliomas and meningiomas, originate within the brain and are directly impacted by the BBB. Secondary brain tumors, or brain metastases, arise when cancer cells spread from other parts of the body (like the breast, lung, or melanoma) to the brain. Both types of tumors create unique challenges for treatment due to the restrictive nature of the BBB.
