Chemotherapy is used to kill cancer cells in people with cancer.
There are a variety of settings in which chemotherapy may be used in people with cancer:
- To cure the cancer without other treatments. Chemotherapy can be used as the primary or sole treatment for cancer.
- After other treatments to kill hidden cancer cells. Chemotherapy can be used after other treatments, such as surgery, to kill any cancer cells that might remain in the body. Doctors call this adjuvant therapy.
- To prepare you for other treatments. Chemotherapy can be used to shrink a tumor so that other treatments, such as radiation and surgery, are possible. Doctors call this neoadjuvant therapy.
- To ease signs and symptoms. Chemotherapy may help relieve signs and symptoms of cancer by killing some of the cancer cells. This is called palliative chemotherapy.
