Genetic Testing for a Predisposition Towards Breast Cancer

Updated: May 28

A Phenomenological Study, Utilizing Bounded Rationality, Exploring the Decision-Making Processes Associated with Genetic Testing for a Predisposition Towards Breast Cancer


Presented at 2020 Carol Carfang Nursing & Healthcare Ethics Conference



The complicated nature of genetic testing requires breast cancer medical professionals, and those diagnosed with breast cancer, to explore multiple outcomes with the understanding that optimal solutions may not be available, thus requiring them to select among satisficing options, and make good decisions based on incomplete information within the context of unknown and dynamic variables.  Through the lens of bounded rationality, the findings reveal that complex decision-making evokes strong emotions, and requires those diagnosed with breast cancer to incorporate a combination of strategies and processes as they maneuver through both linear and non-linear paths for acquiring information, seeking alternatives, and making decisions.


Purpose

The purpose of this study was to explore how those diagnosed with breast cancer navigate the decision-making process associated with genetic testing.

Research Question: What are the main characteristics of rational choice among those who have been diagnosed with breast cancer (or are at a high risk for developing breast cancer) in situations where complexity precludes individual implications?

Descriptive Phenomenology

Phenomenology is both a philosophical practice and psychological scientific method.  Grounded in the works of Kant & Hegel, Husserl became known as the modern-day founder.  Phenomenological research acknowledges that there is a need for understanding a phenomenon in order to improve practice.  Husserl asserts that the aim of phenomenology is the rigorous and unbiased study of things as they appear.  It provides a deeper understanding of lived experiences by making evident the taken-for-granted assumptions of the phenomenon and allows the researcher to adopt an understanding of how the phenomenon presents itself to the participants’ consciousness. Specifically, descriptive phenomenology as an application is pre-transcendental and focuses on how human consciousness relates to the human world.

Themes

Outcomes-Based Decision-Making

 Surgical Options; Impact on Family

Group Decision-Making

Collaboration with spouse; Collaboration with doctors; Collaboration with offspring and relatives

Emotional Orientation

Psychological, Emotional, Stressful, Unexpected

Procedural Strategies

Collection of information; Processing of information

Findings

1.Complex decision-making processes stem not only from the complexity of genetic testing, but also from the information (or lack thereof) that the person has at the beginning of the investigation, i.e., at the time of diagnosis.

2.Complex decision-making involves a shift or alteration in emotion. This is captured from all of the participants as they describe their experience from wanting genetic testing whole-heartedly, to the aftermath and long-term effects, i.e., living with  knowledge of the results (which can’t be reversed). 

3.Complex decision-making can be both linear and non-linear resulting from the outcome of the genetic test.

Findings in Relation to Practice

•Assist medical professionals in understanding the interconnectivity of linear and non-linear processes associated with complex decision-making as they endeavor to advise their patients on genetic testing.

•Assist practitioners in understanding the emotional and psychological impact of genetic testing, and complex decision making, when perfect or complete information is not available.
