In recent decades the improved treatment of childhood cancer has incre
ased the proportion of children being cured. However, the intensive tr
eatment required also implies a heavy burden for the children and thei
r families. The purpose of this article is to judge the ethical aspect
s of different treatment regimens used for children with cancer by mea
ns of a case study. The analysis is based on the ethical model by Beau
champ and Childress. The assessment is based on every person, or group
of persons, involved and is on the principles of autonomy, nonmalefic
ence, beneficence and justice. The analysis shows that intensification
of treatment of children with cancer is ethically justified from a de
ontological point of view. The consequences are more difficult to anti
cipate from a utilitarian perspective.
