Overview of genetic counselling in cancer care

Abstract

The accelerated discovery of disease and susceptibility genes made possible by the sequencing of the human genome has brought new and exciting challenges to the field of genetic counselling. Genetic counselling has therefore been the topic of many studies and wide discussion because of its importance in providing and interpreting genetic information to patients and their relatives. Besides, as the use of genetics in clinical care has increased, both interest in and concern about the impact of genetic information on the life of individuals have been raised. As the scope of genetic counselling therefore expands and evolves, patient, professional and community education will be imperative. Hence, the importance of cancer genetic counselling cannot be over emphasized and it is hoped that this write up will contribute to this quest. Various definitions of genetic counselling and roles were examined; a typical structure was described following a model guideline of pre and post-test counselling. An illumination into vital aspect of family history, pedigree development and its relevant to health care providers especially nurses was also provided.
