Cancer in children is a rare disease of high social and financial cost; differences in regional survival rates result from missing diagnostic and/or therapeutic opportunities. According to the OPS, more than 27,000 cases of cancer are diagnosed each year in children under 14 years in the Americas, leading to an estimate of 10,000 deaths caused by the disease. Most cases of childhood cancer occur in Latin America and the Caribbean where 17,500 new cases are diagnosed each year, resulting in more than 8,000 deaths.
