Comprehensive cancer risk assessment is a consultative service that includes clinical assessment, genetic testing when appropriate, and risk management recommendations delivered in the context of one or more genetic counseling sessions.
Several professional organizations emphasize the importance of genetic counseling in the cancer risk assessment and genetic testing process. Examples of these organizations include the following:
PC-SPES is a mixture of 8 herbs that was sold as a dietary supplement to keep the prostate healthy (see Question 1).
Some batches of PC-SPES were found to contain prescription medicines. It was taken off the market and is no longer being made (see Question 1).
Herbs in PC-SPES have been used in traditional Chinese medicine for many health problems, including prostate problems, for hundreds of years (see Question 2).
The herbs used in PC-SPES have been reported to help keep cancer cells...
Genetic counseling informs the consultand about potential cancer risks and the benefits and limitations of genetic testing and offers an opportunity to consider the potential medical, psychological, familial, and social implications of genetic information.[4,10,11] Descriptions of genetic counseling and the specialized practice of cancer risk assessment counseling are detailed below.
Genetic counseling has been defined by the American Society of Human Genetics as "a communication process that deals with the human problems associated with the occurrence, or risk of occurrence, of a genetic disorder in a family." The process involves an attempt by one or more appropriately trained persons to help the individual or family do the following:
Comprehend the medical facts, including the diagnosis, probable course of the disorder, and the available management.
Appreciate the way that heredity contributes to the disorder, and to the risk of recurrence (occurrence), in specific relatives.
Understand the alternatives for dealing with the risk of recurrence (occurrence).
Choose a course of action that seems to them appropriate in view of their risk, their family goals, and their ethical and religious standards and act in accordance with that decision.
Make the best possible adjustment to the disorder in an affected family member and/or to the risk of recurrence (occurrence) of that disorder.
In 2006, the National Society of Genetic Counselors further refined the definition of genetic counseling to include the process of helping people understand and adapt to the medical, psychological, and familial implications of genetic contributions to disease, including integration of the following:
Interpretation of family and medical histories to assess the chance of disease occurrence or recurrence.
Education about inheritance, testing, management, prevention, resources, and research.
Counseling to promote informed choices and adaptation to the risk or condition.
