Chemotherapy uses anti-cancer (cytotoxic) drugs to destroy cancer cells. Cytotoxic means toxic to cells.
These drugs disrupt the way cancer cells grow and divide, but they also affect normal cells.
Sometimes chemotherapy is given before radiotherapy. This is to shrink the tumour and help to make the radiotherapy more effective.
Chemotherapy may also be used on its own. It may be given to relieve symptoms and improve quality of life if it is not possible to cure the cancer. This is called palliative chemotherapy.
Some people have palliative chemotherapy with a targeted therapy drug.
Chemotherapy drugs are usually given into a vein (intravenously), but some are given as tablets. The drugs travel in the blood, which means they can reach cancer cells that might be elsewhere in the body.
