Chemotherapy aims to inhibit cell division of the cancer cells and kill them, but normal cells are also prone to be affected during treatment. Chemotherapy is usually given over a period of weeks as a series of treatments at set intervals or as a continuous drip into the arm. The aim is that over a period of time a large amount of cancer cells will have been targeted. The chemotherapy drug circulates around the body in the blood stream and is able to target any cancer cells wherever they are within the body. There may be certain side effects from your treatment. Your nurse specialist can discuss these with you.
