### Inspirational Welsh Cancer Campaigner Claire O’Shea Dies Aged 42
The world of cancer support and women’s health advocacy in Wales is mourning the loss of one of its brightest lights. Claire O’Shea, a renowned campaigner for gynaecological cancer awareness, has passed away at the age of 42 following a lengthy struggle with cancer.
Claire, who was based in Cardiff, leaves behind a legacy that has touched countless lives across Wales. Her passing was announced by Tenovus Cancer Care, the charity with which she was closely associated. In their tribute, Tenovus described Claire as a source of inspiration whose determination and warmth had a ripple effect within her community and far beyond.
Claire’s journey to her diagnosis highlights the uphill battle many women face within the healthcare system. For nearly two years, she navigated a cycle of GP visits after being advised her symptoms were due to irritable bowel syndrome (IBS). Unconvinced and persistent, Claire’s breakthrough came after a trip to Istanbul, where a visit to a traditional Turkish hammam spa led to further investigation into her health.
Ultimately, Claire was diagnosed with a rare and aggressive form of cancer known as uterine leiomyosarcoma, which by that point had advanced to stage four, affecting her liver, lungs, and bones. This devastating news did not deter her spirit but rather galvanised her into taking action to ensure other women would not have to endure a similar ordeal of late or mistaken diagnosis.
Reacting to her experience, Claire became a leading advocate for gynaecological cancer awareness. She bravely shared her story with the Senedd’s health and social care committee to shed light on what she saw as a systemic issue — women’s health concerns often being overlooked or misdiagnosed. It was this determination that led her to establish Claire’s Campaign, an initiative to empower Welsh women to speak out and seek the support and attention they deserve on their path to diagnosis and treatment.
Tributes have poured in from across the country. In the official statement from Tenovus Cancer Care, spokespersons expressed their deep sadness at her loss: “Claire’s strength, warmth, and determination inspired hundreds of women to share their experiences and helped drive real change in how gynaecological cancers are understood and addressed across Wales.” The organisation remains committed to carrying her work forward, pledging to honour Claire’s legacy in collaboration with her loved ones and partner charities.
Welsh politician Julie Morgan MS was among the first public figures to pay her respects, noting Claire’s ability to turn personal adversity into a force for good. “She ensured that no other woman would go through what she did without having their voice heard. She will be missed greatly,” Morgan commented, highlighting the profound impact Claire made in just a short time.
Claire’s advocacy work contributed significantly to a Senedd committee report on gynaecological cancer care, which recommended 26 vital improvements to Welsh Government policy. The findings included concerns over a persistent bias within the system that risks patient safety and underscored the need for robust support for women’s health services.
Alongside her campaigning, Claire has empowered a new wave of women across Wales to demand better care and awareness. Her story—one marked by courage in the face of adversity—serves as both a rallying cry and a solemn reminder of the work that remains to be done in women’s health.
As the community of patients, campaigners, and medical professionals comes to terms with her loss, Claire O’Shea’s influence will endure through those she has inspired. Her life’s work continues to shape the policy agenda and personal outlooks of women and their families around Wales.
Claire’s legacy, stitched into the fabric of Welsh healthcare advocacy, will continue through the voices she empowered and the campaigns she set in motion—a testament to how one individual’s resilience can ignite widespread change.
