The types of cancers that develop in children are often different from the types that develop in adults. Unlike many cancers in adults, most childhood cancers are not strongly linked to lifestyle or environmental risk factors. And only a small number of childhood cancers are caused by DNA (gene) changes that are passed from a parent to their child.

The types of cancers are different

There are differences in the types of cancers that children tend to get, as well as how they are treated.

Treatment is often more intense, and more successful

With some exceptions, childhood cancers tend to respond better to certain treatments. This might be because of differences in the cancers themselves, as well as because children often get more intense treatments. Also, children usually don’t have many of the other health problems that adults with cancer might have, which can often get worse with treatment. 

Long-term side effects are more of a concern

On the other hand, children’s bodies are still growing, and they’re more likely to have side effects from some types of treatment. For example, children (especially very young children) are more likely to be affected by radiation therapy. Many cancer treatments also can cause long-term side effects, so children who have had cancer will need careful follow-up for the rest of their lives.

Children with cancer are treated at pediatric cancer centers

In the United States, most children and teens with cancer are treated at a center that is a member of the Children’s Oncology Group (COG). All of these centers are associated with a university or children’s hospital. These centers offer the advantage of being treated by a team of specialists who know the differences between adult and childhood cancers, as well as the unique needs of children and teens with cancer and their families. This team usually includes pediatric oncologists (childhood cancer doctors), surgeons, radiation oncologists, pediatric oncology nurses, physician assistants (PAs), and nurse practitioners (NPs). As we have learned more about treating childhood cancer, it has become even more important that treatment be given by experts in this area.

These centers also have psychologists, social workers, child life specialists, nutritionists, rehabilitation and physical therapists, and educators who can support and educate the entire family. (See Who Treats Children with Cancer? for more on the professionals who help treat children with cancer.)

Any time a child is diagnosed with cancer, it affects every family member and nearly every aspect of the family’s life. You can read more about coping with these changes in If Your Child Is Diagnosed With Cancer.
