Lay summary
Cervical cancer is preventable through vaccination, screening and timely treatment. New Zealand’s cervical screening programme now offers a universal self-testing option which is expected to reduce inequities in participation and cancer outcomes. It is vital that the programme - including facilities, staff, communication and equipment - works for people of all body sizes. Big-bodied people have historically been under-screened, putting them at greater risk of undetected cervical cancer. This research aims to understand how well the new screening pathway, including self-testing, meets the needs of this population. Our pragmatic qualitative approach involves partnering with health and community providers to recruit big-bodied people to share their cervical screening experiences. Findings will guide the development of practical approaches and recommendations for implementing size-inclusive cervical screening with broader relevance across all health services. Investing in the delivery of size-inclusive screening will help improve coverage and achieve downstream reductions in cancer incidence and mortality.
