The GRAACC was established in 1991 to provide all possible alternatives of curing cancer in children and teenagers, preserving quality of life. Its hospital, a model in childhood cancer treatments, provides care for over 4,000 patients from every region in Brazil every year, specializing in high-complexity cases (brain, eye and bone tumors). GRAACC has a technical-scientific partnership with the Federal University of São Paulo (UNIFESP) that enables diagnosing and treating childhood cancer and allows for the development of teaching and research.
