Chemotherapy means treatment with anti-cancer drugs.
These drugs are often used to treat or control obvious disease which may be causing symptoms. Often several different drugs are given together. Chemotherapy may also be given when we know there is a high chance of cancer cells being present in your body. It may not be possible to detect these cells but it is important to destroy them. Cytotoxic drugs are often used as part of a treatment plan, for example before or after an operation or a course of radiotherapy.
