Ethics Behind Genetic Testing in Breast Cancer: A Webinar by Laura Carfang of survivingbreastcancer.org
Reporter: Stephen J. Williams, PhD
The following are Notes from a Webinar sponsored by survivingbreastcancer.org on March 12,2020.
The webinar started with a brief introduction of attendees , most who are breast cancer survivors. Survivingbreastcancer.org is an organization committed to supplying women affected with breast cancer up to date information, including podcasts, webinars, and information for treatment, care, and finding support and support groups.
Some of the comments of survivors:
- being strong
- making sure to not feel overwhelmed on initial diagnosis
- get good information
- sometimes patients have to know to ask for genetic testing as physicians may not offer it
Laura Carfang discussed her study results presented at a bioethics conference in Clearwater, FL on issues driving breast cancer patient’s as well as at-risk women’s decision making process for genetic testing. The study was a phenomenological study in order to determine, through personal lived experiences, what are pivotal choices to make genetic testing decisions in order to improve clinical practice.
The research involved in depth interviews with 6 breast cancer patients (all women) who had undergone breast cancer genetic testing.
Main themes coming from the interviews
- information informing decisions before diagnosis: they did not have an in depth knowledge of cancer or genetics or their inherent risk before the diagnosis.
- these are my genes and I should own it: another common theme among women who were just diagnosed and contemplating whether or not to have genetic testing
- information contributing to decision making after diagnosis: women wanted the option, and they wanted to know if they carry certain genetic mutations and how it would guide their own personal decision to choose the therapy they are most comfortable with and gives them the best chance to treat their cancer (the decision and choice is very personal)
- communicating to family members and children was difficult for the individual affected; women found that there were so many ramifications about talking with family members (how do I tell children, do family members really empathize with what I am going through). Once women were tested they felt a great strain because they now were more concerned with who in their family (daughters) were at risk versus when they first get the diagnosis the bigger concern was obtaining information.
- Decision making to undergo genetic testing not always linear but a nonlinear process where women went from wanting to get tested for the information to not wanting to get tested for reasons surrounding negative concerns surrounding knowing results (discrimination based on results, fear of telling family members)
- Complex decision making involves a shift or alteration in emotion
- The Mayo Clinic has come out with full support of genetic testing and offer to any patient.
Additional resources discussed was a book by Leslie Ferris Yerger “Probably Benign” which discusses misdiagnoses especially when a test comes back as “probably benign” and how she found it was not.

This is very insightful. There is no doubt that there is the bias you refer to. 42 years ago, when I was postdocing in biochemistry/enzymology before completing my residency in pathology, I knew that there were very influential mambers of the faculty, who also had large programs, and attracted exceptional students. My mentor, it was said (although he was a great writer), could draft a project on toilet paper and call the NIH. It can’t be true, but it was a time in our history preceding a great explosion. It is bizarre for me to read now about eNOS and iNOS, and about CaMKII-á, â, ã, ä – isoenzymes. They were overlooked during the search for the genome, so intermediary metabolism took a back seat. But the work on protein conformation, and on the mechanism of action of enzymes and ligand and coenzyme was just out there, and became more important with the research on signaling pathways. The work on the mechanism of pyridine nucleotide isoenzymes preceded the work by Burton Sobel on the MB isoenzyme in heart. The Vietnam War cut into the funding, and it has actually declined linearly since.
A few years later, I was an Associate Professor at a new Medical School and I submitted a proposal that was reviewed by the Chairman of Pharmacology, who was a former Director of NSF. He thought it was good enough. I was a pathologist and it went to a Biochemistry Review Committee. It was approved, but not funded. The verdict was that I would not be able to carry out the studies needed, and they would have approached it differently. A thousand young investigators are out there now with similar letters. I was told that the Department Chairmen have to build up their faculty. It’s harder now than then. So I filed for and received 3 patents based on my work at the suggestion of my brother-in-law. When I took it to Boehringer-Mannheim, they were actually clueless.
