Having a fever means your body temperature is higher than normal. Something inside your body, such as an infection, has caused your temperature to rise.

A number of things can cause fever. This can include some cancers, drugs and other treatment.

Treating a fever depends on what is causing your fever. You can treat the symptoms of fever and make yourself more comfortable.

There are lots of organisations, support groups and helpful books to help you cope with symptoms and side effects caused by cancer and its treatment.
