Imagine facing a heart-wrenching reality where urgent medical concerns for your child are minimized simply because of their age. This is the painful experience that the parents of a teenage girl, who tragically lost her battle with breast cancer, now share. They firmly believe that their daughter could still be alive today if she had been treated with the same urgency typically afforded to adult patients.
Isla Sneddon, a vibrant 17-year-old from Airdrie, passed away in March 2025, just six months after receiving her devastating diagnosis. Her parents, Mark and Michelle Sneddon, assert that her initial symptoms were not taken seriously enough by healthcare professionals, resulting in critical delays in her treatment.
Initially, Isla visited her general practitioner (GP) in July 2022, presenting a lump in her breast. Unfortunately, she was reassured that it was probably benign, attributed to hormonal changes during her adolescence. "She was told it was hormonal—a fibroadenoma—and that she would eventually outgrow it," recounted her father, Mark, reflecting on how this misdiagnosis set off a chain of tragic events.
Fast forward two years, Isla's health took a drastic turn for the worse, prompting another visit to the hospital. This time, the GPs suspected cancer and made an urgent referral for biopsies. However, Isla's parents argue that this referral was downgraded to a routine appointment due to her young age, which led to the cancer going undetected until it was far too late.
After spending ten weeks in the hospital, Isla was finally diagnosed with a sarcoma that had metastasized to her lungs and lymph nodes, ultimately affecting the lining of her heart. The gravity of the situation was laid bare when the oncologist delivered the heartbreaking news: "Your daughter is going to die; she has six months to a year to live."
"Isla didn't want to know; she just wanted to enjoy life to the fullest," Mark expressed, emphasizing the joy and hope they had shared as a family. He reminisced about the dreams he held for his daughter, such as teaching her how to drive and buying her first car—moments he would never have the chance to experience.
Despite the ongoing chemotherapy treatments, Isla’s condition deteriorated, leading to her being readmitted to the hospital in March 2025. Mark revealed that doctors informed them Isla was the "sickest person in the hospital," but the family remained hopeful for a recovery. Sadly, the situation turned dire when they learned that there were no further options available for her care. “We nursed her through six months of chemotherapy, and in the end, she just died in our arms,” he said, a poignant reminder of the fragility of life.
The Sneddons are determined to advocate for change, believing that had there been earlier intervention and if Isla had been treated as an adult presenting with similar symptoms, they might have had more precious time with her. They are campaigning for what they are calling "Isla's Law," which aims to ensure that children and young adults in Scotland receive prompt and equal access to diagnostic tests and treatment as adults do.
Michelle added that Isla's symptoms were often misattributed to anxiety, a common dismissal of concerns in younger patients. However, they later learned that what was initially thought to be anxiety was actually indicative of the underlying cancer. "If a child presents with a lump, anxiety symptoms, chest infections, or tonsillitis—two or three symptoms—the GP should consider a different diagnostic pathway, instead of adhering strictly to existing guidelines," Michelle argued, highlighting a critical flaw in the current system.
The couple suspects that Isla's cancerous tumor may have been quietly developing beneath the surface of what was thought to be a harmless fibroadenoma, growing progressively until it became untreatable. They believe that a thorough investigation, possibly involving a mammogram or advanced imaging, might have unveiled the true nature of Isla’s condition much sooner.
Mark acknowledges that Isla was an unusual case; most children with similar symptoms are likely to be healthy. However, he passionately stated, "I never want another mother or father to feel the way Michelle and I feel right now." The family is gearing up for a meeting with Health Secretary Neil Gray to discuss their concerns, yet Michelle voiced her frustration that any potential legislative changes may be delayed until a new government takes office.
In response to the family's heartache, Arwel Williams, director of acute services at NHS Lanarkshire, stated that the team has been in communication with the Sneddons, assuring them that Isla's treatment followed standard clinical pathways. Nonetheless, he acknowledged the profound impact of their loss and extended heartfelt condolences to the family.
In a statement, the health secretary expressed his sympathies and mentioned that updated cancer referral guidelines, including provisions for children and young people, were published last August in hopes of ensuring timely diagnosis and treatment moving forward.
This situation raises significant questions about how pediatric patients are perceived within the healthcare system. Are their symptoms adequately taken seriously, or do biases based on age lead to potentially fatal oversights? What steps can be taken to ensure that future generations do not suffer the same fate as Isla? We encourage readers to share their thoughts and experiences—let's start a conversation around this crucial issue.
