Question

J.F. is a 26-year-old woman in the clinic today for her annual physical examination. As you take her medical history, it becomes apparent that she is quite concerned about her risk for developing breast cancer. Her mother and a maternal aunt both developed breast cancer in their late 40s. J.F. has heard that genetic testing can be done to see whether she carries “breast cancer genes.”

If genetic testing reveals that J.F. does carry the BRCA1 gene, what does this mean for her risk of developing breast cancer?

Mrs. Ortez has type III breast cancer and is now concluding the trial portion of a certain research study about this condition. She has responding well to the series of neoplastic medications and is currently in remmision. The researchers and her surgeon have informed both mrs Ortez and her husband that there is the possibility that her unique type of cancer could have a genetic foundation. Most at risk would be her 8 year old daughter, through both her 10 yr old and 2 yr old sons could carry the genetic mutation for this cancer. How do you, as her primary nurses, address her concerns for possible genetic testing of her children? Should the identification of the children's risk as possible carriers of this specific gene be identified at this time? Should the testing be even considered to be done at this time?
