Chemotherapy is considered systemic therapy and is used as primary therapy or adjuvant therapy for cancers that may not be confined to a localized body area. Because chemotherapy is systemic, it circulates through many body areas and can harm cancer cells that may be some distance from the primary tumor. Many types of chemotherapy, however, are not able to cross the blood-brain barrier and are not useful for tumors that either develop in the brain or metastasize to the brain.
