In 2007, an estimated 10, 400 new cancer cases were expected to occur
among children aged 0-14 years old.  An estimated 1,545 deaths from
cancer were expected to occur among children in 2007. [31]

Leukemia is the most common cancer in children under 15, accounting
for 30 percent of all childhood cancers, followed by brain and other
nervous system cancers. [32]

Cancer is the second leading cause of death among children ages 1 to
14 years of age, with unintentional injuries being the leading cause. [33]

The causes of childhood cancer are poorly understood, though
different forms of cancer have different causes.[34] Parental and
childhood exposure to pesticides and radiation may cause certain
cancers in children. [35]
