Brain Metastasis

A brain metastases are tumors that originate from the central nervous system (CNS) and spread secondarily to the CNS via haematogenous route or by direct invasion from adjacent tissues.

Brain metastases are the most common cause of intracranial mass lesions, and up to 45% of cancer patients eventually develop brain metastases during the course of their illness.
As primary cancer treatments such as surgery, radiation therapy, Cyber Knife and chemotherapy have become more effective in the past few decades, people with cancer are living longer after initial treatment than ever before.

Brain metastases have a poor prognosis for cure, but modern treatments are allowing patients to live months and sometimes years after the diagnosis.
