Marisa Kimmel: Going Flat After a BRCA1 Diagnosis, and Defining Womanhood for Yourself
Walking the Genetic Line
Episode summary When Marisa Kimmel chose aesthetic flat closure after learning she carried a BRCA1 mutation, she wasn’t thinking about whether she would still feel like a woman. She was thinking about lowering her risk so she could stay alive for her six-month-old son. The question of femininity came later, handed to her by strangers on social media. Marisa had already done this work once. She was diagnosed with alopecia at nine, and years of trying to hold on to her hair took such a toll on her mental health that she came close to not wanting to be alive. Letting go of her hair taught her...

Rachel Collier: Genetic Counseling Is More Than a Blood Draw, and Testing Is Always a Choice
Walking the Genetic Line
Episode summary Many people walk into a genetic counseling appointment expecting a blood draw. Rachel Collier wants them to know there is far more available: education, informed consent, and real space to talk through what this information could mean for their lives. Because genetic results are information you can’t unlearn, she treats testing as a true choice, including the choice not to test. Rachel describes how hereditary cancer risk tends to become real in two phases, first in the initial appointment, when memories of relatives’ cancer treatment can resurface, and again when results...

Randi Eichenbaum: BRCA2, Access to Care, and the birth of MOTA
Walking the Genetic Line
Episode summary Randi Eichenbaum was 19 when her mother died of ovarian cancer. Somewhere in those years she absorbed a quiet belief: this is going to happen to me too. Years later, a new OB-GYN recommended genetic testing based on her family history. The BRCA2 result came by phone from a third-party lab while she was at work, followed by an emailed PDF that no one walked her through. She put it in a drawer, literally and figuratively, and went back to work. What followed was a series of turning points. She became a mother and experienced acute postpartum anxiety. She had a prophylactic...

Jaclyn Carnevale: From Cancer Diagnosis to Embryos Without the Mutation, A BRIP1 Previvor’s IVF Journey
Walking the Genetic Line
Episode summary In May 2022, at 30 years old, Jaclyn found a lump in her breast. Her doctor, seeing no family history and a young, healthy patient, suggested she wait a week and see if it was still there. Jaclyn didn't take no for an answer — she asked for a mammogram, and within a single day learned she had DCIS, an early-stage breast cancer. What came next moved at a speed she describes as "medical timeline on fast forward": genetic counseling that flagged something didn't add up in her family's supposedly cancer-free history, a large genetic panel that turned up a mutation called BRIP1,...

Kathy Baker: Founding My Faulty Gene & Surviving Hereditary Cancer
Walking the Genetic Line
EPISODE SUMMARY Kathy Baker grew up in a family that, as she puts it, "looked like a poster for a BRCA mutation" — a sister diagnosed with breast cancer at 31, a mother with three primary cancers, a grandfather lost to aggressive prostate cancer, a great-grandmother lost to pancreatic cancer. And still, when genetic testing became available, Kathy said no. Not out of denial exactly, but out of a fierce instinct to protect her own life from being lived under a shadow. She was diagnosed with breast cancer herself in 2000, treated without ever seeing an oncologist first, and then spent nine...

Elana Silber: The Chain You Inherit
Walking the Genetic Line
EPISODE SUMMARY Sharsheret is the Hebrew word for chain. Not a ribbon, not a fight, not a cure — a chain. Twenty-five years in, that name turns out to be the most precise available description of the work: over 40,000 people who have shared their experience, peer matches made not by mutation status but by the specific thing you are afraid of, social workers and genetic counselors who answer the phone, pre- and post-surgery kits arriving at the house wrapped and unbilled, and more than a million dollars a year moving quietly toward the non-medical costs that make a diagnosis expensive in ways...

Holly Taylor: Hard-Earned Wisdom
Walking the Genetic Line
Episode Summary A visible tumor changed two lives at once. When Holly Taylor’s sister was diagnosed at 45 with simultaneous stage 3 ovarian and breast cancer — tumors large enough to see with the naked eye, discovered only after years of avoiding care without health insurance — genetic testing entered Holly’s life as an extension of her sister’s crisis rather than a decision of her own. An initial variant of unknown significance sat unresolved for two years before being reclassified as a pathogenic BRCA1 mutation, arriving in the middle of a four-and-a-half-year caregiving arc that...

Marleah Dean Kruzel: You Make the Best Decision You Can — A Researcher’s Honest Take on BRCA and Uncertainty
Walking the Genetic Line
Guest: Marleah Dean Kruzel, PhD Theme: Uncertainty as a Lifetime Companion, Not a Problem to Solve Episode Summary Marleah Dean Kruzel was 8 years old when her mother found a lump. What followed were years of surgeries, chemotherapy, radiation, and a childhood lived largely in hospitals — experiences that eventually became the foundation of a research career dedicated to understanding what previvors actually go through, and what the systems meant to support them consistently fail to provide. She tested positive for BRCA2 in 2013, after letting the test kit sit in the back of her safe for...

Natalie Samson Hart: How Integrative Genetic Counseling Changes What Comes Next
Walking the Genetic Line
Guest: Natalie Samson Hart, MS, CGC, INHC Theme: Genetic Counseling as a Gateway to Whole-Person Care Episode Summary Natalie Samson Hart didn’t come to oncology genetic counseling through a tidy career trajectory. She came through loss, confusion, and proximity to illness — a brother whose neurodivergence led her toward the intersection of science and human connection, a father diagnosed with stage 4 cancer while she was still in graduate school and rotating through cancer wards. That collision of the personal and professional is what eventually pushed her out of traditional...

Krista Brown: ATM Mutation, Delayed Diagnosis, and What Self-Advocacy Actually Costs
Walking the Genetic Line
Guest: Krista (Oncology Nurse Navigator) Theme: Self-Advocacy, ATM Mutation, Cancer After Previvorhood EPISODE SUMMARY When Krista's mother was 48, she became the first known cancer diagnosis in their family. She tested negative for BRCA mutations and felt relief — relief that she wouldn't pass anything on to her children. Twelve years later, just before entering hospice, she was offered expanded genetic testing and found out she carried a pathogenic ATM variant. She shared those results with her children. A few months after her death, Krista — 38 years old, a nurse, carrying...
info_outlineEpisode summary
When Marisa Kimmel chose aesthetic flat closure after learning she carried a BRCA1 mutation, she wasn’t thinking about whether she would still feel like a woman. She was thinking about lowering her risk so she could stay alive for her six-month-old son. The question of femininity came later, handed to her by strangers on social media. Marisa had already done this work once. She was diagnosed with alopecia at nine, and years of trying to hold on to her hair took such a toll on her mental health that she came close to not wanting to be alive. Letting go of her hair taught her that she is a woman because she says she is. Today she feels more feminine and grounded in her womanhood than she ever has, without the two features society treats as proof.
In this second conversation, Sara and Marisa go deeper into what that freedom costs and what it makes possible. Marisa talks about choosing not to delete hostile comments, because people considering the same choices deserve to know that choosing yourself isn’t all good. She describes raising a son who answers questions about his long hair with total certainty, and her plan to let him decide if and when to learn his own genetic risk. She shares the moment her father, also a BRCA carrier, asked her to put a shirt on, and what came out when she asked why: guilt. Sara reflects on the parallel between Marisa’s longing to protect her son and her father’s grief over what he passed down, and on why this podcast exists to complicate the tidy story of risk, surgery, and safety.

Highlights & takeaways
-
“I’m a woman because I say that I am.” After a lifetime with alopecia and a choice to go flat, Marisa defines her womanhood from the inside out.
-
“I actually didn’t even have that thought in my head once before. It was given to me by other people.” Fears about femininity after mastectomy can be absorbed from others rather than coming from within.
-
“It’s not all good, choosing yourself.” Claiming your body can bring judgment and conflict. Marisa leaves hostile comments up so others can see the full picture before making similar choices.
-
When her father asked her to cover her scars, the reason turned out to be guilt. A parent’s grief about passing down a mutation is real, and it doesn’t have to become the child’s to carry.
-
Sara names a parallel process: Marisa’s longing to protect her son echoes her father’s wish that he could have protected her.
-
“The more that I talk, say the hard things out loud, the softer they feel.” Speaking about what’s hard makes it easier to carry.
