Overdose of Chemotherapy in a 9 month infant

Dear Ask The Doctor: Ive just recieved a call from my sister and ive been informed that my 9 month old nephew has been given a double dosage of chemotherapy by mistake and has been rushed back to hospital. what will this mean?

Dear Paula: It is difficult to say what consequence the overdose of chemotherapy will have on your nephew. Chemotherapy side effects are different for each child. The type of anticancer drug used, the dosage, and a child's general health affect the risk of developing unpleasant side effects.
