How Cancer Changed My Plans for Motherhood | HuffPost

This HuffPost Canada page is maintained as part of an online archive.

Because my cancer was hormone-sensitive, I need to take a drug called Tamoxifen that is proven to reduce the risk of the cancer returning and possibly spreading to another part of my body. The newest recommendation is to stay on this drug for 10 years. Great news, right? A drug that could actually help keep me alive. I am lucky to have that option. Unfortunately, hormonal therapy for cancer comes with a whack of side effects. The biggest one for me is that I've been told not to get pregnant while taking it, due to its potential to cause birth defects.

I always took it for granted that I would, someday, have children.

I never grappled with the decision of whether or not motherhood was for me, or thought of what my life might be like without kids. I made mental notes of my favourite baby names, and imagined what they might look like. After meeting and marrying my husband, the desire to start a family grew stronger. Maybe she'll have his eyes and my mouth, I thought. I hope he gets my husband's athletic ability, and not mine. I dreamed and planned and let my mind wander to a future that I thought was secure.

I made an appointment with my doctor, thinking maybe we'd broach the subject of stopping my birth control pill. I felt nervous and giddy at the thought. How did I get here? Was I really ready for this? What if there was a problem?

And then, there was a problem.

A week before my doctor's appointment, I found a lump in my breast.

I changed the purpose of the appointment to talk about boobs instead of babies. And after several tests and a couple weeks of waiting, I received the diagnosis. Breast cancer. I had just celebrated my 28th birthday and had been married for less than a year. And, ironically, I did end up coming off my pill, but not for the reason I had intended; rather, the breast cancer I had was fueled by estrogen (a main ingredient of the birth control pill), so I was told to immediately stop taking it. No more pill. But no baby either. To say things were not going according to plan would be a massive understatement.

In the same conversation where I learned I had an invasive, aggressive breast cancer, I also learned that the chemotherapy I'd need to undergo could cause fertility issues. Major double whammy.

At first anything other than the fact that I might die seemed inconsequential. But after taking some time to process everything and meeting with a fertility specialist, the reality set in that there was now a possibility I'd never have children. I was devastated.

I considered undergoing fertility preservation treatment and went through the initial steps, but ultimately pulled out at the eleventh hour due to timing factors, enrolling myself in a clinical trial, and not being comfortable at that point with injecting hormones into my body. We decided to accept the risks, and hope for the best.

Now I am two and a half years past my diagnosis, and my baby-making clock is ticking once again. Time to get a move on, right?

Not so fast.

Because my cancer was hormone-sensitive, I need to take a drug called Tamoxifen that is proven to reduce the risk of the cancer returning and possibly spreading to another part of my body. The newest recommendation is to stay on this drug for 10 years. Great news, right? A drug that could actually help keep me alive. I am lucky to have that option.

Unfortunately, hormonal therapy for cancer comes with a whack of side effects. The biggest one for me is that I've been told not to get pregnant while taking it, due to its potential to cause birth defects.

I am 30 years old now and have been taking Tamoxifen for almost two years. If I stay the course of 5-10 years, and take into account my chemo-aged ovaries... well, you can do the math.

So now I find myself again in a sticky situation, forced to make another difficult decision on top of the ones I've already had to face. (Fertility preservation? Double or single mastectomy? Radiation? Reconstruction? Cancer has a way of forcing you to be decisive.)

The way I usually make my decisions is to read up on all the research and literature I can possibly find. But in this case, there are no studies assessing the risk of pausing hormonal therapy to get pregnant. Zilch! As Dr. Susan Love writes, "We are frequently asked what would happen if a woman stopped taking tamoxifen between two years and five years, and the truth is that we just don't know because we have no studies that have looked at that question...Because there is no data to support stopping early, this has to be a personal decision, and it is undoubtedly not an easy decision for many women to make."

I constantly toss scenarios around in my head, playing out the various possibilities. What if I continue treatment, and by the time I'm done, I've missed my window to get pregnant? What if I stop taking my pill, get pregnant, and I end up dying and not being able to raise the kid I just had? What if I take a break, get pregnant, go back on Tamoxifen and we all live happily ever after? (Obviously this third scenario is the one I cross my fingers for.)

In my case, these are the cards I've been dealt, and I won't be able to get the answers I need by the time I need them. But the really good news is that young women with breast cancer in the future will have the data they need to make an informed decision.

The POSITIVE 'Baby Time' trial will investigate if interrupting hormonal (endocrine) therapy to get pregnant increases the risk of breast cancer recurrence. This is the exact study that, had it been done ten years ago, I might not find myself in the situation I'm in right now.

I'm so excited and proud that Rethink Breast Cancer (where I happen to work) is committing to funding the Canadian arm of this international trial. They need to raise a lot of money to make this happen, so please give generously! Your contribution will make a huge difference to so many young women who one day may be walking the same path I'm on. And let me tell you, anything that can make that journey even a little bit easier, is worth doing.

And as for me, I'm not sure where my choices might lead me, or how this story will end. But I have hope. Hope that I'll have the family I wanted, hope that I'll live to see that family grow, and hope that pregnancy will be a possibility for all those young women who follow behind me in the years to come.

There is always hope.

Not All Stem Cells Are Created Equal(01 of17)

Dr. Mick Bhatia in Hamilton discovered that human stem cells made from adult donor cells remembered what cell types they came from. When reprogrammed in the lab they preferentially reverted to their original cell type. Dr Bhatia’s discovery will have important implications for new stem cell therapies. Via Nature Communications, Dec. 2014. (credit:Gary Caviness via Getty Images)

Mapping The Evolution Of Cancer Cells(02 of17)

Dr. Samuel Aparicio and Dr. Sohrab Shah in Vancouver made important discoveries that shed light on how cancer cells evolve in tumours. The researchers developed a new tool to group genetic mutations in a single tumour and used it to predict how cells in breast cancers evolve and grow over time. Understanding and predicting changes in complex cancers may provide new options for targeted treatments. Via Nature, Nov. 2014. (credit:Adrianna Williams via Getty Images)

Gene Mutation Could Be Leukemia Trigger(03 of17)

In Toronto, Dr. John Dick investigated the importance of over 100 genes commonly mutated in the early stages of leukemia. He found that a mutation in the gene DNMT3A plays a key role, making cells with this mutation resistant to chemotherapy and faster growing than normal stem cells. These findings identify a possible starting point for the disease which could help doctors diagnose and treat patients earlier. Via Nature, April 2014. (credit:Frantab via Getty Images)

Genetic Test To Predict Prostate Cancer Relapse(04 of17)

Dr. Robert Bristow in Toronto was part of an international team that developed a genetic test to predict which men are at highest risk of their prostate cancers returning following treatment. This test provides a way to identify patients who need more aggressive treatments, while avoiding over-treatment for patients whose cancers are less likely to return. Via Lancet Oncology, Nov. 2014.

Gene Mutations Linked To Lung Cancer Risk(05 of17)

Dr. Rayjean Hung in Toronto was part of an international research team that found rare variations of the BRCA2 and CHEK2 genes associated with squamous cell lung cancer in people of European ancestry. They also found genetic links for lung adenocarcinoma with a gene variation previously only reported in Asian populations. These findings contribute new knowledge about the genetic basis of lung cancer and have implications for the screening of high-risk individuals with these inherited mutations.

Long-Term Effects Of Treatment For Childhood Brain Cancer(06 of17)

A study led by Dr. Donald Mabbott in Toronto found that children treated for medulloblastoma, a childhood brain cancer, had smaller regions of the brain associated with learning and memory, which was also linked to impairment in these abilities. This study highlights the need for more targeted therapies that minimize the late effects of treatment on survivors. Via Journal of the International Neuropsychological Society, Jan. 2014.

Banning Patio Smoking Helps Smokers To Quit(07 of17)

Dr. Michael Chaiton in Toronto led a survey of over 3,000 smokers about their exposure to smoke on patios and found that smokers were less likely to be successful in their quitting efforts after being exposed to tobacco smoke on a patio. These findings were used as evidence to support an Ontario government ban on smoking on patios, playgrounds and other outdoor public spaces. Via Tobacco Control, Oct. 2014.

Too Many Carbs Could Fuel Colorectal Cancer(08 of17)

Genetics, diet and gut microbes all contribute to the development of colorectal cancer, but how these factors work together to promote cancer is not well understood. Dr. Alberto Martin in Toronto investigated these connections in a mouse model of colorectal cancer and found that gut microbes resulting from a diet high in carbohydrates interacted with cancer-causing genes to fuel cancer development. These findings have important implications for reducing cancer risk by changing diet and the make-up of gut microbes. Via Cell, July 2014. (credit:Adam Gault via Getty Images)

The Costs And Benefits Of Lung Cancer Screening(09 of17)

A study led by Dr. Stuart Peacock in Vancouver showed that the average costs of screening individuals at high risk for lung cancer and treating cancerous growths discovered through early detection were lower than the costs of treating advanced lung cancer. These findings provide important information to policymakers considering the value of lung cancer screening programs in high-risk groups. Via Journal of Thoracic Oncology, Oct. 2014.

Making Immunotherapies Work For More People(10 of17)

Harnessing the immune system’s powerful ability to fight cancer, Dr. Claude Perreault in Montreal has identified new molecules that attract T cells, the body’s natural killing machines which help fight off germs and diseases. Dr. Perreault used a new approach to identify molecules that attract the T cell’s cancer-fighting abilities. These findings could help increase the number of cancer patients who could benefit from immunotherapies. Via Nature Communications, April 2014. (credit:caracterdesign via Getty Images)

A Walking School Bus(11 of17)

This year, the Canadian Cancer Society developed "Trottibus," a network that walks children to school instead of having them ride the bus, in Quebec. The initiative is meant to increase physical activity to help prevent the development of disease like cancer.

Testing For Radon Can Save Lives(12 of17)

"Radon, a colourless and odourless gas emitted through soil, is believed to be responsible for 16 per cent of lung cancer deaths in the country each year .. It's estimated that 3,000 Canadians die from lung cancer caused by radon annually." (credit:National Cancer Institute via Getty Images)

We Need To Stand Up More(13 of17)

This year, evidence was found that showed an increased risk for colon and endometrial cancers with every increase of two hours of sitting per day, reported Scientific American. Moreover, it didn't matter how active the people were outside of those hours of sitting — the risk remained the same regardless. (credit:Boston Globe via Getty Images)

Calories Coming To Menus Could Halt Obesity(14 of17)

Ontario Health Minister Deb Matthews hopes to pass a proposed law that would see chain restaurants include calories on their menus in order to help the public make more informed choices with their food, reported The Star. The correlation between obesity and disease — including heart problems and cancer — is well-established. (credit:Hero Images via Getty Images)

Manitoba To Ban Indoor Tanning For Minors(15 of17)

The most recent province to ban children under 18 from using tanning beds, Manitoba's new law is expected to come into play in the spring, according to Global News. Anyone who exposes themselves to UV lights even once before the age of 35 can significantly increase the risk of skin cancer, Cancer Care Manitoba's Elizabeth Harland told the network.
