The Heritability of Cancer: The Impact of Parental Cancer on Children

Listen to ASCO's Journal of Clinical Oncology essay, "The Heritability of Cancer" by Dr. Leeat Granek, Associate Professor at York University in Toronto, Canada. The essay is followed by an interview with Granek and host Dr. Lidia Schapira. Granek shares how her mother's diagnose with breast cancer continues to shape her own life and experiences.

TRANSCRIPT

Narrator: The Heritability of Cancer, by Leeat Granek

I was 9 years old when my mother was first diagnosed with breast cancer and 25 when she died. The boundary between before and after is so clear that it feels like I have lived two lives. I went from being a careless, cerebral, quirky child to a rough version of the responsible, reliable, and vigilant adult I would eventually became. With cancer came the fear of losing my mother, and with that fear came an unwelcome but necessary maturity. There were other important life events impacting our family around that time that contributed to this sense of split. We had just moved from Israel to Toronto and knew few people in our new environment. My mother had just given birth to my baby brother, and my parents had bought a new house for our growing family. At the time, I was starting third grade in a new school—the fifth new school since beginning kindergarten. All this in addition to the diagnosis. My mother was only 33 years old—the same age I am now.

While I adapted to everything else—new house, new school, new brother, new country—cancer insisted on sticking around, and it claimed not only my mother's life but, in many ways, my own. Cancer enters the body of the caregivers in ways that move far beyond the domestic work involved in the running of the house or the management of medications and appointments. It can become part of caregiver DNA through inherited genes, but it often does so in more insidious ways.

My mother lived with the disease for 17 years before she died in 2005. It is fair to say I grew up in the hospital. Over the years, there were multiple surgeries, along with episodes of weekly chemotherapy and daily radiation sessions. She suffered a host of complications that came with metastatic disease and its treatment, including four instances of strep A bacteremia. Many major events happened in the hospital. We ate Chinese food with our matzos on Passover in her room and lit Hanukkah candles in the waiting room where we accidentally set off the fire alarm on the seventh night, to the consternation of the nursing staff. My 11th, 15th, 18th, and 25th birthdays were celebrated in cramped hospital quarters, cutting the birthday cake with a dull plastic knife. Indeed, the last birthday we had together was my 25th, and we marked it in the hospital 2 days before she died. In her last lucid moment, she managed to miraculously lift out of the fog caused by brain metastases to give me a kiss and exclaim "Mazal tov, Leeatie!"

I remember the sounds and the smells. Static codes being called out over the hospital loudspeakers. The haunting "clink, clink, clink" of the staples being removed from my mother's skin graft and landing with a loud clatter in a silver bowl. The pale green hallways and their antiseptic smell, which I grew to hate. The airless temperature that was neither hot nor cold—hospital weather, I used to call it. The hospital, with its sounds and smells, was my second home.

It sounds awful. And it was a lot of the time, but there were many good moments as well. My mother was smart, intuitive, funny, and astonishingly optimistic. She was always laughing and incredibly giving with her love and affection. We were exceptionally close. Her eyes lit up and her arms stretched out to give me a hug every single time I walked into her room. She would say things like, "Leeatie, I love you so much. I wouldn't change a single thing about you! How did I get to be so lucky to have a daughter like you?" and "There's no one in the world I would rather spend time with than you." I didn't have to do anything to earn her affection. I felt that I always came first, that I was always wanted and loved, and that my mother was always entirely there for me in every sense of the word.

The hospital days that punctuated much of my childhood, adolescence, and young adulthood were both an annoyance and a blessing. There was nothing else to do but simply be together, which was fun and easy, thankfully. When I was older and no longer living at home, I would sometimes sleep over in her hospital room during her admissions. We would curl up in the twin bed and talk for hours until we both fell asleep, or we would sit together, each absorbed in her own book, comforted by the warmness of being together.

When I think about being a caregiver for my mom, and by extension a caregiver for our family, it was not the hours of care work—the babysitting, driving to appointments, spending time in the hospital—that consumed me. The impact was long-lasting and continues to this day. As a health psychologist and a researcher in the area of psychooncology, I know the permanent and long-term devastations cancer causes throughout the caregiver's—in my case, the daughter's—entire life span. To this day, I have no real sense of what normal physical development for a woman should feel and look like, and in some sense, I never will. I entered puberty around the same time my mother was having her breasts and ovaries removed, which made that phase frightening and emotionally difficult. And now, I have no mother to turn to and ask about my endlessly evolving female form, no mother to guide me through future pregnancies or talk me through gray hair and menopause.

Cancer shaped my young adulthood and my emotional development. At 20 years old, I was dealing with issues facing 60-year-olds who care for ill and aging parents. Because part of me recognized that time was running out—indeed, because I lived almost my entire life with a neon awareness of my mother's mortality—I was tethered to home and making decisions about school, life, and love that would keep me close to her. I don't regret these choices or a single moment that I chose to spend with her, and now I have an entire lifetime to come and go as I please. Being challenged with a cancer-driven perspective at 20, however, carries risks of having an entire lifetime being developmentally out of step with one's peers and unprepared for life events outside a hospital. For example, at 25, I could look death in the face without trembling and without abandoning my mother at her end, but I was unprepared to face the dating world that most young adults would have no trouble navigating. Although I was and remain a loved, nurtured, and supported daughter, cancer diverted the vast majority of the temporal, emotional, financial, and physical resources in our family toward fighting the disease. When she was alive, my mother was fully present in my life. But even her unconditional love could not repair the reality of my out-of-sync development as a child and young adult or today make up for her continued absence in my life.

My absent mother is at the core of a black hole of grief that remains inside of me and that has been painfully pried open with subsequent losses to cancer—my grandmother and my aunt, a professor I admired and family friend that I loved. Each loss re-exposes a haunting grief I have learned to accept and live with. Grief is a shadow that looms large in my life. It is both the topic I chose to study and the affect I advocate fiercely for,1–4 because as I have learned through my own experiences and research, love and light come from the same place as grief and darkness.

The ability to grieve our losses fully also allows us to love and appreciate the people in our lives when they are still with us.

And then, of course, there is the worry: the biannual check-ups, magnetic resonance imaging scans, and mammograms; the surveillance and the false positives and the constant paradoxical tension that comes with the awareness of the nature of these tests provide a false sense of control over a disease that refuses to be harnessed.

The literature about the impact of parental cancer on children at the time of diagnosis, during treatment, after surgery, and even at the time of death is extensive,5–6 but few of these studies acknowledge how much this disease alters the life course of the child well after the parent has recovered or has died. Being a caregiver for a patient with cancer consumed much of my childhood, adolescence, and young adulthood when my mother was alive and charted the course for my future as a health psychologist working in the field of psychooncology. Although many years have passed and although I have a doctorate in hand, several years of postdoctoral training in the field of psychooncology, an academic career studying these issues, and dozens of publications from my research on the psychological and emotional effects of cancer on patients, caregivers, and their families,7–16 from time to time, I still feel like a scared 9-year-old child trying to gain control over this disease and get out of the shadow that cancer has cast on my life.

Dr. Lidia Schapira: Hello, and welcome to JCO's Cancer Stories, the Art of Oncology, which features essays and personal reflections from authors exploring their experience in the field of oncology. I'm your host, Dr. Lidia Schapira. I'm a Professor of Medicine at Stanford University. Today we are joined by Dr. Leeat Granek, Associate Professor at York University in Toronto, Canada, in the School of Social Policy and Health Management. In this episode, we will be talking about her Art of Oncology article, "The Heritability of Cancer." At the time of this recording, our guest has no disclosures. Leeat, welcome to our podcast and thank you for joining us.

Dr. Leeat Granek: Thank you so much for having me. It's a pleasure.

Dr. Lidia Schapira: Your essay is a classic, and I'm so glad that we were able to include it in the recent anthology of Art of Oncology. So let's start by talking a little bit about what led you to not only write, but decide to share this essay eight years after your mother passed of breast cancer. Bring us to that moment. Tell us what you were thinking.

Dr. Leeat Granek: Yeah, so that's a great question. And I recently, in preparation for this interview, reread it, and I was a little taken aback, even by how exposed and how vulnerable it was. But I really like that essay, and I'm really glad that it was published. It was kind of a culmination of a lot of thoughts that I was having as a person who has researched grief for many years, and as a person who was working in the field of psycho oncology, doing research in the area, and as a grieving daughter. And I think eight years is nothing in the grieving trajectory, right? We often think about grief as something acute that happens to you, and then you get over it and you move on with your life, and that certainly has not been my experience of grieving. I think it changes as you change, and it's just a constant presence in your life.

And I was thinking about that in the context of being a caregiver for somebody who has cancer. So I think my experience is a little different than others, just because my mom was very young. She was 33 when she was diagnosed, and I was only nine. And she lived with this metastatic disease for nearly 20 years. So we had a very long journey with cancer. And I can kind of see now, as I reread it, the parallel thinking processes I had about grief and about cancer. And being a researcher in the field, I still feel that there are a lot of gaps in terms of the caregiver experience. But this idea of heritability, we often think about cancer as something you inherit genetically through our genetic makeup. But I think that it really, especially when you're young, changes your whole life trajectory. And I could not find anything in the literature that spoke about it in that very longitudinal kind of way and the way the impact of cancer changes you throughout your entire life. And so it just came from a very personal place, but also that intersection of being aware of the different literatures and how they came together.

Dr. Lidia Schapira: Let's unpack this a little bit. One of the things that you just said was that you shared your vulnerabilities, and I want to ask you a little bit more about that. Here you are. You're about the same age that when your mother was living with this as a young woman. I think you said that she was diagnosed roughly at the time that you were writing this. And you decide to explore this wearing a little bit of your research hat in a very deeply personal way. But then the question I wanted to ask you is your decision to share this with the community of oncologists, the people you knew very well because they had looked after your mother for all those years. Tell me a little bit about that. How did you make the decision not only to write it, but to share it?

Dr. Leeat Granek: That's a great question. This also pertains to the research that I do, because a lot of the research I was doing at the time, as a result of my experiences with cancer teams as a child, looked at the emotional impact of being an oncologist. I did a series of studies looking at the way oncologists grieve and how they feel when patients die, some of the emotional burdens of the work. And they were very vulnerable in sharing their experiences. And so I thought, well, they're telling me about their experiences, I can also tell them about mine. And I think that there's kind of a mythology around oncologists. I'm doing studies now on surgeons as well, and I think there's the same mythology around surgeons is that they don't feel or everything is compartmentalized and everything's separate.

But from my research, I knew that that wasn't the case. And I felt that, although oncologists and oncology teams and nurses as well, witness patient suffering and family suffering, that there was nothing in the literature that kind of brought it home in this very visceral way. I don't think it would have been a surprise for any oncologist reading it, because when you follow families or when you follow parents, you see the children coming in. And so there was something about this intersection of their vulnerability and my vulnerability, enriching the experience of what it means to be a patient, and what does it mean to be a healthcare provider, which is not something that's often discussed in medicine at all.

Dr. Lidia Schapira: So to your point, I think that telling the story was a beautiful sort of vehicle for opening up the topic. You were doing it through your research. But telling a story can often start a conversation in a very different way. That's what we try to do also in selecting these essays for Art of Oncology, to bring a story that's deeply personal, that reflects one's lived experience, but opens up a topic that is otherwise perhaps not talked about as much as we think it should. So let me go back and ask, what was the impact of telling the story on your research?

Dr. Leeat Granek: I just want to add something about what you just said about stories. The very first paper that I published on oncologist experiences of grief, I wrote an op-ed for the New York Times about that research. And it was very story-based. It was very much telling a story, and I was telling my own story as well as a story about the research. And the response to that op-ed was so profound and so much more powerful than any paper I had ever published. I got thousands of emails from people around the world, oncologists and healthcare providers around the world, just saying how touched and how moved they were by that op-ed. And that is the power of the story that you're talking about right now, that we're vying for these peer-reviewed articles all the time. But actually, the impact of just telling a story is so much more meaningful and visceral for the reader than just outlining the research findings.

Dr. Lidia Schapira: And it sounds like just receiving all of those emails after your op-ed was probably very validating. We can get rejected when we apply for grants, but people were telling you what you're onto is really significant.

Dr. Leeat Granek: Yeah. And I think that validating in the sense that what I felt was that as you, exactly the words you just used, that it was a conversation that was not being had to the detriment of all. And so it validated that feeling of, yeah, this is something that's really important for us to be talking about in oncology. And just in terms of the response to "The Heritability of Cancer," it was a long time ago. This is 2014, so 10 years ago. I don't remember entirely what are the specific things that people said, but I do remember getting a lot of emails about it, mostly from healthcare providers, so less from caregivers or patients who may not have subscriptions to JCO, but maybe through the podcast now will have more access. Just saying this really shed some light as to the experience of what does it mean for the extended family that I think is not often considered. Certainly, we don't think about kids very often when a parent is going through cancer.

Dr. Lidia Schapira: If you were to write this today, what would you do differently?

Dr. Leeat Granek: I think what's changed for me– I don't think I would do anything differently, but what I think has changed is that I've had a child since I written that. Having a seven-year-old and thinking about what it's like to be going through a cancer diagnosis or cancer treatment while you have children. That piece was very centered on me and my experiences, and now I have even another layer of empathy and compassion for my mom, who had a newborn at the time. And I can just not imagine anything more– it's going to make me cry just even now just by thinking about it - it's just scary to have such a life-threatening diagnosis when you're a parent. Just like grief, like I said earlier, being a victim of cancer or being part of your family, that impact is lifelong and it changes as your development changes. Now as a parent, my grief is different than it was before I became a parent. And now as a parent, my understanding of what my mother was going through is changed. That terror and fear is so overwhelming.

Dr. Lidia Schapira: So, Leeat, I can't help myself, but I need to ask you some practical questions. You're a psycho-oncologist, an expert in grief, and you've talked to and interviewed hundreds of oncologists who have shared stories, you're now a parent, you've lived through it. What it makes me think is that when we think about grief counseling or support for grieving children or bereaved spouses or parents, you think about it as an acute intervention and what you're suggesting is this needs to be explored throughout the life cycle. What are your thoughts about that and what should we be thinking about?

Dr. Leeat Granek: I've written a lot about this in my grief work. The evidence for psychological counseling for grief is not strong actually when we look at the literature. For acute grief experiences in the immediate aftermath, sometimes it's helpful having someone to talk to. But in actuality, the most helpful is having a community in which grief is an open, accepted, acknowledged, part of living life. And that does not change after the first month or the first six months or the year, five years or ten years.

Other people may have moved on very quickly, but you're left with the impact of that loss. And I think the impact of that loss is not only after, when the person has died, it's also that progressive loss of function. The kind of witnessing of your loved one deteriorating. It's not just meals that you need, you also need that emotional support. And that emotional support doesn't necessarily have to take the form of, "Tell me about your grieving right now." Sometimes it's just being with. And I think that certainly in North America, we're not very good at integrating grief, loss, pain, suffering, and negative emotions into our day to day lives. So partly, 10 years, 20 years, or 25 years later, it's hard for people to remember that loss.

So I think the person is grieving that many years after may have to reach out and ask for the support. But I think it's done really well in certain religions. I am Jewish and in the Jewish background, you have so many layers of mourning that's lifelong. So you have the acute grieving experience where it's seven days or 30 days or one year. And then every year progressively after that four times a year, you say a blessing and remembrance and give charity in the name of the dead. And for religious people, I'm not religious, this idea of every single day for that first year having to go synagogue and having to have at least nine other people that could be there with you to say the prayer for the dead, whether you believe or not believe, whether you're religious or not, I think the brilliance in those kinds of rituals is that it simply brings you together with other people who see you everyday.

And decades later, still that four times a year that you're meeting with people and you're saying a prayer, or that yearly yahrzeit, that memorial allows people a very very defined space in which to support the mourner. And I think other religions have it too.

Dr. Lidia Schapira: Those are beautiful thoughts, and I think it speaks to connection and community as a way of supporting rather than pathologizing the grief and thinking what one needs is some sort of a professional intervention. I can't help but add that as a community of caring oncologists, we are constantly grieving. We are immersed in grief, and in part, there is no label for how we feel. There is a small literature that you probably know far better than I do on disenfranchised grief, which is the idea that we can't quite claim to grieve because we weren't a relative or best friend, but we deeply cared and we lost and we grieve. So I find that this conversation is so helpful because I think what we're doing is we're talking about what we ought to be talking about more: perhaps acknowledging more from a point of view, as you say, of a parent, researcher, caregiver, medical or healthcare professional who's involved. We are living in a society where perhaps we are afraid to think that grief is a part of our life, and we can be happy even if we grieve.

Dr. Leeat Granek: Yeah.

Dr. Lidia Schapira: Happiness is not just the absence of sadness, I think, I don't know. You are the psycho-oncologist, tell me if I'm wrong.

Dr. Leeat Granek: I so appreciate what you're saying and it makes me sad to hear that grief is still so stigmatized among oncologists. I think what my research has found and all my conversations with people over the decades now is, of course, oncologists feel a lot of things. Not just grief but pain and suffering, distress at seeing their patients and their families suffering and declining. Why wouldn't they? They are human beings. So I think this idea that people don't feel or don't have space to feel is part of what leads to burn out actually. I think there's a kind of fear that grief and the pain and suffering is the burn out but it's not. In fact, what's the burn out is the inability to talk about or to have a space to discuss it.

And I also think that the thing that gives meaning to the work is that relationship with patients. And by the way, I'm finding that with the surgeons as well. The surgeons are even more kind of disconnected in terms of emotions. We kind of assume that they feel nothing, that they are so disconnected. By the way, I just have to say, the surgeons say, "I can't believe the oncologists does that job." They find it really hard to believe that oncologists can do that, that they can never do that job. And the oncologists say that about the surgeons, too. So I think it's very interesting how different medical groups look at each other.

But there's this kind of sense that's very unique about the grieving experience of how care providers is and they feel a lot of guilt and a lot of self doubt, and self criticism when patients die even though they know consciously that there's nothing that they could've done and that is just the disease that is taking over. That lack of control and that sense of having failed the patient is so strong. That is a very unique grieving experience for providers who feel responsible for the care of their patients. The fact that there is no training or no education or no space to talk about that is just appalling to me as a psychologist. Because I just think you learn how to do everything else. There's so much training on communicating bad news, on dealing with patient anger, on dealing with patient emotions and how to respond. But nothing on how to deal with your own emotions in response to this. For years, it's just about communications training.

One of the things we find in the literature is that even when you provide communication training to oncologists that have to discuss end of life, often those skills are not sufficient to be able to have that conversation. And what's missing is the notion that I found in my own research that they don't have this conversation because they feel so uncomfortable with it themselves. And so until they have some self reflective practice for healthcare providers, all the skills training in the world is not going to help because it's about your own emotional resistance.

Dr. Lidia Schapira: Well, this has been a phenomenal conversation, and I hope people will look at some of the beautiful research you've done in this field. Thank you so much for having shared your own experience, for the work you do, and for participating in today's podcast.
