It is meant to be used for educational purposes. It contains general disease information, signs and symptoms, and diagnosis and treatment options for ACTs. This section also provides information about genetics and molecular aspects of adrenocortical tumors. We encourage physicians managing children with ACT to contact us for further discussion about their cases.
