As the drugs are carried through your blood stream they are easily absorbed and can kill all the cancer cells in your body. Chemotherapy can be given in different ways, either by mouth or by an injection into the blood stream. Chemotherapy has to be planned carefully for each person, so the cancer is destroyed during your course of treatment.
Most chemotherapy is given on set days over a few months.
Your doctors will tell you how long your treatment will take and how often you will need to have it. In the Adventures of Captain Chemo, two of the characters are named after chemotherapy drugs. They are Vincristine and Etoposide, drugs that are often used to treat teenagers and children with cancer.
