Chemotherapy
Chemotherapy is a systemic cancer treatment that uses powerful drugs to kill rapidly dividing cancer cells throughout the body. It can be administered orally (as pills) or intravenously (through a vein), and treatment may take place in an outpatient clinic or, in some cases, in an inpatient setting.
Chemotherapy is often used as the primary treatment for cancers that have spread or are at high risk of spreading.
It may also be given before surgery (neoadjuvant) to shrink a tumor or after surgery (adjuvant) to eliminate any remaining cancer cells and reduce the risk of recurrence.
Side effects are common but manageable, as healthy cells that divide rapidly are also affected.
