A type of treatment that uses chemical agents to destroy infections and diseases within the body. In modern usage, this therapy has been adopted as a cancer treatment to help destroy cancer cells. Chemotherapy proceeds by stopping or slowing the growth of cancer cells, which typically grow and divide quickly.
Chemotherapy may be given to an individual in many ways:
- Injection – The individual is given a shot typically in their arm, thigh or hip muscle.
- Intra-arterial – The chemotherapy goes directly into the artery that is feeding the cancer.
- Intraperitoneal – The chemotherapy goes directly into an area that contains organs such as your intestines, stomach, liver, and ovaries.
- Intravenous – The chemotherapy goes directly into a vein.
- Topically – The individual is given a type of chemotherapy cream to rub onto their skin.
- Orally – The chemotherapy comes in pills, capsules, or liquids that an individual must swallow.
