Central nervous system metastasis

Central nervous system (CNS) metastasis occurs when cancer cells spread from their original site (like the breast, lung, or colon) to the brain or spinal cord. This can happen through the bloodstream or by invading nearby tissues. CNS metastasis can lead to various symptoms, such as headaches, seizures, or neurological changes, depending on the location and size of the tumors. Treating metastasis in the CNS can be challenging, often involving a combination of surgery, radiation therapy, and chemotherapy, and it represents a serious condition that requires specialized medical care.
