Metastatic breast tumors can lead to pressure and swelling in the brain. Your doctor may prescribe a corticosteroid such as dexamethasone to manage these symptoms.
About one-third of people with brain metastases eventually develop seizures. Seizures can affect different functions such as movement, consciousness, and speech. Your doctor may prescribe an anti-seizure medication such as Dilantin (chemical name: phenytoin), Depakote (chemical name: valproate), or Keppra (chemical name: levetiracetam) to prevent seizures or control their symptoms.
