Chemotherapy is a treatment option that uses drugs to kill cancer cells or to make them less active. Chemotherapy is usually suggested when the cancer cells have spread to a few different parts of the body and also for patients who had undergone surgery for cancer, to prevent relapse.
Chemotherapy is a cocktail of drugs administered in different ways:
- Intravenous (IV) - Chemotherapy goes directly into a vein, given as infusion.
- Intra-arterial (IA) - Chemotherapy goes directly into the artery that is feeding cancer.
- Intraperitoneal (IP) - Chemotherapy goes directly into the peritoneal cavity (the area that organs such as intestines, stomach, liver, and ovaries).
- Topical - Chemotherapy comes in a cream that you rub onto your skin. Oral - Chemotherapy comes in pills, capsules, or liquids that you swallow.
