A woman has just been diagnosed with breast cancer.
ANSWER:- Breast cancer is a complex illness that may be impacted by several variables such as lifestyle, environment, and genetics. The BRCA1 breast cancer susceptibility gene has been linked to an increased risk of developing breast and ovarian cancer in women. Identical twins have the same genetic makeup; if one twin is diagnosed with breast cancer, the other twin is more likely to get the condition.
Numerous considerations must be considered if one identical twin is concerned about acquiring the cancer gene. Genetic testing may give helpful information about the likelihood of getting breast cancer. Nonetheless, the choice to undertake genetic testing should be made with caution and in consultation with a healthcare expert. The daughter should be told that genetic testing is entirely optional and that she has the option not to be tested.
Moreover, if the daughter tests positive for the BRCA1 gene mutation, she should be made aware of the risk-reduction options, which include preventative surgery, heightened monitoring, and lifestyle changes. Moreover, it is critical to address with her the psychological and emotional ramifications of genetic testing and how the results may affect her life and future goals.
The ethical difficulties that arise when one identical twin wants to know her genetic vulnerability to an illness while the other does not are complicated. In such instances, protecting each twin’s individuality and privacy is critical. Healthcare practitioners should ensure that the twin who does not want to undergo genetic testing is not pushed or bullied into it. It’s also crucial to preserve confidentiality and keep the findings of the genetic testing secret since releasing the information to the twin who doesn’t want to know may create unnecessary worry and anxiety.
Finally, the choice to undertake BRCA1 genetic testing is personal and should be taken thoughtfully and in consultation with a healthcare practitioner. Moreover, ethical factors must be considered when dealing with identical twins who may have opposing viewpoints on genetic testing.
QUESTION:- A woman has just been diagnosed with breast cancer. Her doctor tells her that while cancer is a multifactorial disease, she carries the breast cancer susceptibility gene, BRCA1. One of her two identical twin 19-year-old daughters is afraid that she also may have inherited the gene (Chapter 4, Learning Objective 2, 3, 8).
What considerations would you give her daughter who is worried about inheriting the cancer gene?
What ethical issues are raised when one identical twin wants to know her genetic susceptibility to a disease and other does not?
