Chemotherapy
Chemotherapy is the use of anticancer drugs to treat cancerous cells. Chemotherapy has been used for many years and is one of the most common treatments for cancer. In most cases, chemotherapy works by interfering with the cancer cell's ability to grow or reproduce.
Different groups of drugs work in different ways to fight cancer cells. Chemotherapy may be used alone for some types of cancer or in combination with other treatments such as radiation or surgery. Often, a combination of chemotherapy drugs is used to fight a specific cancer. Certain chemotherapy drugs may be given in a specific order depending on the type of cancer it is being used to treat.
While chemotherapy can be quite effective in treating certain cancers, chemotherapy drugs reach all parts of the body, not just the cancer cells. Because of this, there may be many side effects during treatment. Being able to anticipate these side effects can help you and your caregivers prepare, and, in some cases prevent these symptoms from occurring.
How is chemotherapy administered?
Chemotherapy can be given:
- As a pill to swallow
- As an injection into the muscle or fat tissue
- Intravenously (directly to the bloodstream; also called IV)
- Intrathecally (chemotherapy given directly into the spinal column with a needle)
