Although childhood cancer is rare, approximately 13,000 children under the age of 20 will be diagnosed with cancer this year. Cancer affects people of all age, sex, race, geographical location and social status. Oncology, the study of cancer and tumors, has made significant progress in the prevention, treatment and prognosis of many childhood cancers. Despite this progress, cancer is the third most common cause of death in children ages 1 to 19.
Childhood cancer varies from adult cancers in development, treatment, response to therapy, tolerance of therapy and prognosis. In most cases, childhood cancer is more responsive to therapy, the child can tolerate more aggressive therapy and the prognosis is better.
The future direction of oncology involves genetic research and improved treatment options. Discovery of certain "cancer genes" has made significant breakthroughs in the study of cancer. Much more investigation into human genes and development are still needed to understand cancer.
