Fit Dad, 42, Dies of Lung Cancer After Shock Diagnosis
22 Nov, 2025
Summary
- A fit 42-year-old Army pilot died months after a sudden lung cancer diagnosis.
- He never smoked and had no typical symptoms, making the diagnosis a shock.
- The cancer spread rapidly to his brain and bones after diagnosis.
Rob Collingwood, a fit 42-year-old Army Air Corps pilot and father of two, was diagnosed with stage 4 lung cancer on his birthday in April 2022 and passed away in April 2023. His wife, Harriet, shared their story, emphasizing the shock of the diagnosis given Rob's healthy lifestyle and lack of typical symptoms. He had never smoked, was always active, and enjoyed playing rugby with their son.
Subtle personality changes preceded his diagnosis, followed by severe pneumonia which led to the discovery of a large tumor. By then, the cancer had already metastasized to his brain and bones. Harriet noted that a prior bout of pneumonia 18 months earlier, during which NHS investigations were limited, might have been a missed opportunity for early detection.
The couple navigated telling their young children about Rob's illness with support from the Ruth Strauss Foundation. Despite the immense challenges, Rob lived by his motto, 'We can do hard things,' focusing on making memories with his children. His legacy is one of courage, love, and living fully, reminding others that lung cancer can affect anyone, regardless of smoking status.
