Stories of Long-Term Survivors Living Over 10 Years with HER2 Breast Cancer

Surviving Years with HER2-Positive Breast Cancer

HER2-positive breast cancer is an aggressive subtype representing about 20-25% of all breast cancers. While HER2 cancers were once associated with poorer prognosis, the development of targeted HER2 therapies now allows many patients to survive long term and even thrive as long-haulers.

The Changing Landscape for HER2 Breast Cancer

Since HER2-positive breast cancers grow and spread more rapidly without treatment, diagnosis was once feared with high recurrence risks and lower 5-year survival rates. However, outcomes have dramatically improved over the last 20 years thanks to advances in targeted antibody therapies and combination treatment regimens.

The monoclonal antibody trastuzumab, sold under brand name Herceptin, specifically targets the HER2 protein to block tumor cell proliferation signals. Approval of this pioneering drug for metastatic HER2 breast cancer in 1998 revolutionized survivorship.

Improved Life Expectancy Outlook

Prior to HER2-directed options, average survival for Stage 4 metastatic HER2-positive breast cancer was estimated to be about 2 years from diagnosis. With incorporation of targeted agents, 5-year survival rates now reach up to 75% extending long term projections.

For patients with non-metastatic early stage HER2 breast cancers, 5-year survival statistics now mirror rates for hormone receptor-positive at around 93% thanks to improvements in systemic therapies.

Meet Long-Term HER2 Breast Cancer Survivors

While prognosis following a HER2 breast cancer diagnosis has shifted favorably in recent decades, much uncertainty around longevity, recurrence risk and quality of life implications still remains.

Hearing from those who have journeyed years beyond diagnosis as long-haulers can provide needed perspective and inspiration to patients beginning their own path forward.

11 Years and Counting

At age 39, Julie was diagnosed with early stage HER2-positive breast cancer after finding a lump through self-exam. Following a bilateral mastectomy, chemotherapy and targeted drug treatments, she has celebrated 11 years cancer-free and now advocates for survivor resources.

While the treatments were challenging, Julie emphasizes taking it one day at a time rather than fixating on longevity statistics which vary widely across individuals based on response.

Still Going Strong at 14 Years

Upon finding blood-tinged discharge at age 44, genetic testing revealed Destiny carried the BRCA mutation making her high risk for triple negative breast cancer. After opting for preemptive bilateral mastectomy, pathology surprisingly uncovered early stage HER2-positive cancer.

Now 14 years out from diagnosis, Destiny maintains annual screening and cardiac testing but has been able to watch her daughter grow up cancer-free. She hopes her story encourages newly diagnosed women that long term survival is possible.

20 Years and Counting

At age 44, Maggie underwent her first breast cancer biopsy for a palpable mass which confirmed HER2-positive Stage 2 disease. Following treatment with surgery, chemotherapy and radiation, she experienced recurrence 2 years later with metastasis to lymph nodes requiring more aggressive therapies.

Now 20 years from original diagnosis, Maggies disease remains stable on maintenance Herceptin. She offers hope to others diagnosis with advanced disease that there are long term treatment options and life goes on!

Advice from Long-Haulers for the Newly Diagnosed

HER2-positive survivors who have lived 10, 15 or even 20+ years provide valuable wisdom gained from their own resilience.

Connect with Others Who Understand

While family and friends provide vital support, speaking with fellow HER2 thrivers who comprehend the unique challenges faced can help long-haulers feel less alone. Support groups also give opportunities to learn about emerging therapies and clinical trials from those further along in the journey.

Take Time to Heal Emotionally Too

Coping mentally, emotionally and spiritually after a HER2 breast cancer diagnosis is equally as important as the physical recovery journey. Whether through counseling, meditation techniques, journaling or other wellness practices, self-care allows space to process the trauma in the midst of treatment rigors.

Celebrate Milestones

Reframing thoughts away from fearing recurrence towards celebrating NED (no evidence of disease) status and each survival milestone can profoundly shift mindset. HER2 thrivers recommend marking infusions, scan anniversaries, birthdays or holidays after diagnosis as affirmations of hope.

While HER2-positive diagnosis once carried bleaker outlooks, outcomes continue to improve drastically thanks to better treatments allowing long term disease-free survival. By learning lessons from those who have endured years ahead, newly diagnosed women can move forward with greater confidence each day at a time, finding community and meaning along the way.
