Side effects and late effects of treatment

Cancer treatment 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.

For information about side effects that begin during treatment for cancer, see our Side Effects of Cancer Treatment page.

Problems from cancer treatment that begin 6 months or later after treatment and continue for months or years are called late effects. Physical problems, such as problems with fertility, may be a late effect of treatment.

Some late effects may be treated or controlled. It is important to talk with your child's doctors about the possible late effects caused by some treatments. Learn more about Late Effects of Treatment for Childhood Cancer.
