Several factors influence whether a given person with the variant will actually develop cancer. The onslaught of genetic innovations in the past decade has resulted in the ongoing identification of a spectrum of genes, some of which, when mutated, result in cancer susceptibility. Confirm the diagnosis of hereditary cancer syndrome. Informed consent is an essential requirement for any genetic laboratory analysis and for all actions based on its results.
