Not all chemotherapy drugs work the same way and there are many different types of chemotherapy. This is a head-to-toe treatment approach which makes it different from surgery and radiation.
Curative – used to treat the cancer with the goal of it never coming back.
Maintenance – used to control the tumor by keeping it from growing or spreading and can be given routinely for extended periods of time, until the tumor response or a new treatment regimen is needed.
Palliative – used in advanced stage cancer with the goal of shrinking the tumor to ease symptoms and improve quality of life.
