Cancer Genetics Overview (PDQ®): Genetics - Health Professional Information [NCI] - Structure and Content of PDQ Summaries

PDQ cancer genetics summaries focus on the genetics of specific cancers, inherited cancer syndromes, and the ethical, social, and psychological implications of cancer genetics knowledge. Sections on the genetics of specific cancers include syndrome-specific information on the risk implications of a family history of cancer, the prevalence and characteristics of cancer-predisposing mutations, known modifiers of genetic risk, opportunities for genetic testing, outcomes of genetic counseling and testing, and interventions available for people with increased cancer risk resulting from an inherited predisposition.

The source of medical literature cited in PDQ cancer genetics summaries is peer-reviewed scientific publications, the quality and reliability of which is evaluated in terms of levels of evidence. Where relevant, the level of evidence is cited, or particular strengths of a study or limitations of the evidence are described.

In addition, established methods for evaluating the quality of the evidence are available for some, but not all, aspects of...
