Rebecca Castano-Mander, now 41, endured years of misdiagnosis for her severe bowel issues, which doctors often attributed to low iron and stress. As a child, she suffered from constipation, and by her twenties, she faced debilitating faecal impactions requiring hospital interventions. Despite her persistent symptoms, medical professionals repeatedly dismissed her concerns, labeling them as 'probably just IBS' or hormonal changes. At 35, after her husband noticed a strange metallic smell following her bathroom visits, she finally received a colonoscopy that revealed a 25mm cancerous tumor in her transverse colon. This diagnosis, while alarming, provided a sense of validation for Rebecca, who felt relieved to know she was not imagining her suffering. Post-surgery complications arose, including a hemorrhage, further complicating her recovery. A year later, another tumor and 12 polyps were discovered. Today, Rebecca advocates for self-advocacy in healthcare, urging others to trust their instincts and seek answers when faced with persistent health issues. She credits improved gut health for enhancing her quality of life, highlighting the emotional scars that remain from her medical journey.
