The Department of Oncology at Hospital Infantil de México Federico Gómez (HIMFG) was the first unit in our country, and one of the first in Latin America, to specialize in the management of children with cancer. The HIMFG is part of the National Institutes of Health of Mexico, and is a reference hospital with research, educative, and tertiary care medical function. To date, the HIMFG and the Instituto Nacional de Pediatria are the principal medical centers in which children with cancer receive comprehensive care.
