Cancer treatments can cause side effects. Which side effects your child might have depends on the type of treatment they receive, the dose, and how their body reacts. Talk with your child's treatment team about which side effects to look for and ways to manage them.

Problems from cancer treatment that begin 6 months or later after treatment and continue for months or years are called late effects. Late effects of cancer treatment may include:
physical problems
changes in mood, feelings, thinking, learning, or memory
second cancers (new types of cancer)
Some late effects may be treated or controlled. It is important to talk with your child's doctors about the long-term effects cancer treatment can have on your child. Learn more about Late Effects of Treatment for Childhood Cancer.
