While a fever may be a sign of a serious infection in anyone, in a child with cancer, it can be quite serious. Left untreated, your child could become very ill. If your child has a fever, call your health care provider right away. Do not wait until your medical facility opens.

When taking your child’s temperature, do so by mouth or under the arm. Do not take a rectal temperature; this could cause bleeding or infection. Make sure you have a thermometer at home that works and that you know how to use it. Talk with your healthcare team about fever guidelines at your hospital.
