The Breast Cancer Diagnosis That Never Should Have Happened

If ever there was a person who anticipated a breast cancer diagnosis less than me, I’d love to meet her/him. Even after my first mammogram at age 40 resulted in a biopsy – followed by several more in the ensuing years – breast cancer wasn’t on my radar. Call me naive, in denial, or stubborn, I was convinced my doctors were simply being cautious and thorough. As one after the other of those biopsies read negative for cancer, I went on with life, building my nutrition and fitness business and putting each experience behind me and out of my mind until the next scheduled mammogram demanded I pay attention. By November 2013 they’d read negative for so long, I graduated back to “screening” vs “diagnostic” mammograms. But I didn’t even make it to one screening mammogram. In October 2014, seven weeks after completing the Chicago Half-Marathon where I logged a PR (personal record) and felt like a million bucks – thank you very much – I was diagnosed with Stage 1 invasive ductal carcinoma (IDC). Breast cancer. To this day, I continue to marvel at how my body could harbor breast cancer – whose number one goal was to kill me – while at the same time be in peak physical condition.

The Insanity-Inducing Cycle of Disbelief. . .

Shortly after my diagnosis I was in the shower, once again in tears, pleading with the universe to tell me “why?” Not “why me?” “Why?” I had no family history, maintained a healthy weight, ate a vegan diet, got plenty of sleep, and worked out 6-7 days every week. I couldn’t wrap my head around how I, a ridiculously healthy woman, who prided herself on taking zero medication and visiting her doctor only for an annual wellness visit had been thrust into a near constant round of appointments with breast surgeons, oncologists, and radiologists. How was I even qualified to participate in conversations littered with references to pathology reports, clinical outcomes, and surgery requiring the skill of a plastic surgeon, conversations demanding that even as I reeled from this devastating news I make critical, don’t-get-no-second-chance decisions on a dizzying array of treatment options? Breast cancer was so far outside my reality that even as I paced the surgical pre-op room prior to my lumpectomy, I refused to believe it. There was simply no way that breast cancer was actually my life.

. . .and Rage

Although my disbelief was wickedly potent on its own, apparently it required a sidekick, and found it in the companion emotion of rage. Subtle but ruthless, rage wrapped itself tightly around my brain and nervous system, rendering me impatient with and angry at the world. Regardless of how many miles I ran or pounds of weight I lifted, I constantly battled the urge to break glass, punch walls and throw something. . . . ..anything. In time, I’d had enough. Riding the rage wave was exhausting. I realized how desperately I needed to harness that corrosive anger, turn it around and into something good. One year after my diagnosis, still struggling, seeking clarity and answers, I attended a women’s empowerment summit in NYC. While there were many inspiring speakers, the one I’m forever indebted to challenged us with this: “What pisses you off? Use THAT to fuel the change you want to see in the world.”

What pisses me off is this:
  • Every TWO MINUTES a woman is diagnosed with breast cancer.
  • 675 women PER DAY.
  • 246,660 women PER YEAR.
The changes I so desperately want to see are:
  • A worldwide reduction in the total number of breast cancer diagnoses.
  • A single, trusted resource on diet, exercise and living a health-supportive lifestyle for the breast cancer community to access at the time of diagnosis.

The “Why” Turned “What If?” Behind My Mission-Driven Business

Ever so slowly, instead of “why?”, I began to ask “what if?”

  • What if?. . .I could drive down the number of women diagnosed from 1:8 to 1:80 with prevention-focused nutrition and fitness habits.
  • What if?. . .I could help women who are diagnosed use nutrition and fitness to build physical resilience for improved outcomes and optimal healing.
  • What if?. . .I could end confusion, frustration and anxiety in the breast cancer community over what to eat, how and when to exercise, and what it takes to create and sustain a health-supportive lifestyle.

Ever so slowly, I began to get clarity. My 20 years of experience as a wellness and prevention-focused dietitian and nutrition therapist combined with my own breast cancer experience provided a rich opportunity to serve others. I saw how I could use my expertise, skills, voice and professional platform to bring about change for those facing (and living with) the most commonly diagnosed cancer for women worldwide. Although I had no idea what that would look like, I knew. . .

  • It had to be big, bold, broad and intentional
  • It had to be built on actionable behaviors versus passive awareness

And there was no way I couldn’t NOT do it. Finding my voice and the courage to share about my breast cancer – which I’d kept extremely private – channeling my anger into action, and shifting my focus to serving others became the fuel behind the creation of the “DAM. MAD. About Breast Cancer.”™ initiative. I’m a zealot for living a healthy lifestyle that blends plant-based nutrition with physical activity, and integrating the science and psychology of nutrition, fitness and self-care completely lights me up. I’m not a breast cancer researcher. I’m not an oncology dietitian. I’m not even a nutrition and fitness expert who claims to have all the answers. What I am, is DAM. MAD., and I’m on a mission to serve the breast cancer community through education and inspiration to “BITE Back” with nutrition, “MOVE Back” with fitness, and “STRIKE Back” with health-supportive lifestyle strategies – especially at the time of diagnosis. If you’re DAM. MAD. about breast cancer, join me. Yes, you CAN take charge of your health, even at this critical time. . .and it’s my honor to help you.
