How Childhood Cancers Differ From Adult Cancers
We sometimes look at children and only see smaller versions of ourselves. But when we look deeper, we know that children have needs, wants, likes, dislikes, and even medical issues that vary greatly from their adult counterparts. Pediatric oncologists and other physicians who work with children are very aware of these differences. Childhood cancers are quite different from cancers in adults.
Differences Between Childhood and Adult Cancers
Childhood cancers differ from adult cancers in many ways.
Childhood cancers are much less common than cancers in adults. Cancers in children and adolescents account for a small percentage of all cancers that are diagnosed.
Risk Factors and Causes
Many cancers that affect adults are related to lifestyle risk factors such as tobacco or alcohol use, poor diet, or sedentary lifestyle. On the other hand, the causes of most childhood cancers are not known.
Types of Cancers
Childhood cancers tend to occur at different sites from those common in adults. Among the most common childhood cancers are
Most adults who are diagnosed with cancer are treated in their local community by their primary care physicians and cancer specialists. Children’s cancers are much more rare than those of adults, so specialists in many smaller communities do not have continuing experience with the management of these diseases. For this reason, children usually are best treated by teams of doctors who specialize in the diagnosis, treatment, and management of childhood cancers. Such teams are much more likely to be found in eminent children’s hospitals, university medical centers, and cancer centers.
Over the past 20 years, there has been an increase in the number of children diagnosed with cancer. But, according to the National Cancer Institute, the death rate has decreased and the five-year survival rate has increased.
Common Childhood Cancers
The most common childhood cancers are leukemias, lymphomas, brain tumors, and bone cancers.
Young children are most likely to have a type of leukemia called
Non-Hodgkin’s lymphoma is more common in very young children, while Hodgkin’s disease is more common in adolescents.
The incidence of brain tumors peaks between the ages of 5-10. Brain tumors occur somewhat more often in boys than girls.
There are many other uncommon childhood cancers that cancer specialists are called upon to diagnose and treat. Fortunately, effective therapies exist for many of these cancers. The diagnosis of cancer can be a trying time for a child and family, but helpful and caring treatment can make a difference.
