The primary goal of this effort is to foster expanded access to and continued advances in medical care provided to patients and families affected by hereditary cancer syndromes. The 1996 ASCO Statement on Genetic Testing for Cancer Susceptibility set forth specific recommendations relating to clinical practice research needs educational opportunities requirement for informed consent indications for genetic testing regulation of laboratories and protection from discrimination as well as access to and reimbursement for cancer genetics services. In updating this Statement ASCO endorses the following principles Indications for Genetic Testing ASCO recommends that genetic testing be offered when 1 the individual has personal or family history features suggestive of a genetic cancer susceptibility condition 2 the test can be adequately interpreted and 3 the results will aid in diagnosis or influence the medical or surgical management of the patient or family members at hereditary risk of cancer. ASCO recommends that genetic testing only be done in the setting of pre- and post-test counseling which should include discussion of possible risks and benefts of cancer early detection and prevention modalities.
