What is chemotherapy?
Chemotherapy is the use of anticancer drugs designed to slow or stop the growth of rapidly dividing cancer cells in the body. The drugs may be used:
- As a primary treatment to destroy cancer cells
- Before another treatment to shrink a tumor
- After another treatment to destroy any remaining cancer cells
- To relieve symptoms of advanced cancer
Chemotherapy delivery methods
Some chemotherapy delivery methods include:
- Orally (by mouth as a pill or liquid)
- Intravenously (by infusion into a vein)
- Topically (as a cream on the skin)
- Direct placement (via a lumbar puncture or device placed under the scalp)
When chemotherapy drugs travel through the bloodstream to reach cells throughout the body, it is called systemic chemotherapy. When chemotherapy drugs are directed to a specific area of the body, it is called regional chemotherapy.
