My Stage 4 Cancer Symptoms Were DISMISSED! - Leah | Stage 4 Lung Cancer

I was diagnosed with stage IV non-small cell lung cancer with an EGFR exon 19 mutation at 43 years old in December 2019. I had been a stay-at-home mom for 19 years, raising three children—my oldest heading to college, my daughter nearing the end of high school, and my youngest in middle school.

Around mid-September 2019, I developed a dry, persistent cough. At first, I didn’t think much of it because I was frequently around young children who often had minor illnesses. After a couple of weeks, I visited my primary care physician, who diagnosed it as a post-viral cough and prescribed steroids. I initially felt better, but the symptoms returned within weeks, along with shortness of breath.

As a former distance runner, I noticed a significant change. I could maintain my pace, but I couldn’t carry on a conversation while running without becoming winded. I returned to the doctor and was told it was exercise-induced asthma. That didn’t feel right to me. I sought further evaluation from an allergist, who ruled out asthma.

My symptoms worsened. I felt constant fatigue, chest heaviness, and suspected pneumonia. I requested a chest X-ray, but the doctor initially resisted, saying it wasn’t necessary. Eventually, the scan revealed consolidation in my right lung, and I was treated for pneumonia with antibiotics and steroids. Despite treatment, my condition continued to decline. I began coughing up blood and experiencing severe breathing difficulties.

I was hospitalized for four days with what was believed to be antibiotic-resistant pneumonia. During that time, a bronchoscopy was performed, but no abnormalities were found beyond inflammation. After discharge, my symptoms persisted and worsened. I struggled to breathe, experienced pain in my chest, ribs, and shoulder, and lost weight.

Frustrated and concerned, I returned to the doctor’s office and insisted on being seen. A nurse practitioner listened carefully and arranged for a CT scan. Later that day, I received a call indicating concerning findings, and I was instructed to go to the emergency room.

At the hospital, a doctor showed me my scan results, which revealed lesions in my spine highly suspicious for metastatic cancer. Further testing confirmed malignant fluid in my lung and, eventually, a bone biopsy identified stage IV lung cancer. I had visited doctors multiple times before receiving this diagnosis.

Initially, I was told I had 6 to 12 months to live. That prognosis was unacceptable to my family, and we sought another opinion. A second oncologist suggested biomarker testing, which revealed the EGFR mutation driving my cancer. This allowed me to begin targeted therapy with Tagrisso in late December 2019.

The response to treatment was significant. Over time, my primary lung tumor shrank by 70%, and my bone metastases began healing. After about a year, I underwent targeted radiation therapy to further address the primary tumor. Since then, I have remained stable with no progression.

I continue to take targeted therapy daily and undergo regular scans. While this treatment is not a cure and resistance is expected over time, I have already exceeded the typical response duration. Future treatment options will depend on how the cancer evolves.

This experience has reinforced the importance of self-advocacy. I had to push for testing, question diagnoses, and insist on further evaluation. If something feels wrong, it is essential to pursue answers. A second opinion is not optional in serious conditions—it is necessary.

I also recognize that not everyone has the same resources or support, which makes advocacy even more important. Early dismissal of symptoms can delay critical diagnoses. Trusting your body and persisting in seeking care can make a difference.

Despite the challenges, I have chosen to focus on living fully each day. I remind myself that statistics do not define individual outcomes. While survival rates may appear discouraging, someone has to be in the group that exceeds them.

I approach each day with intention, focusing on small moments and meaningful experiences. Whether it is spending time with family or enjoying simple activities, every day holds value. I also aim to support others facing similar diagnoses by sharing my experience.

Cancer brings uncertainty, but it also brings perspective. It highlights what truly matters and encourages a deeper appreciation for life. While the journey is difficult, it is still possible to find purpose, connection, and hope.
