What is Brain Metastasis?
What are the Causes of Brain Metastasis?Any primary tumor that can spread to the brain is termed as brain metastasis.
Primary tumors of the lung, breast, kidney, colon, genitourinary tract, gastrointestinal tract, and the skin (melanoma) metastasize to the brain. Melanoma has the highest likelihood (nearly 50%) to metastasize to the brain.
Most common sources of brain metastases: The most common sources of brain metastases are lung, melanoma, and breast cancers. The tumor cells travel to the brain through the venous system (Batson’s plexus) that passes out from the skull and the spinal column or through the extensions of the sinus or the arteries.
