<strong>Introduction:</strong><br/> Women attending breast screening may have suspicious mammographic findings that are subsequently found at assessment clinic to be normal (false positive, FP). A false positive diagnosis is not harmless, with short and long term negative psychosocial consequences reported. Women are at increased relative risk of breast cancer therefore their attendance at subsequent screening is essential.<br/>\ud \ud <strong>Aims:</strong> <br/>To assess the impact of FP breast screening diagnosis and diagnostic work-up on re-attendance rates across four consecutive screening rounds at a typical breast screening centre. <br/>\ud \ud <strong>Method:<br/></strong> Diagnostic interventions and screening re-attendance rates at one prior and two consecutive rounds were analysed for women receiving a FP diagnosis between 2004-2006. <br/>\ud \ud <strong>Results:</strong><br/> 397 women (5.57%) were referred for further assessment, including 228 (57.43%) false positives. 34 eligible women failed to re-attend routine screening (+ 3 years), with 17 failing to re-attend subsequently (+ 6 years). 70.6% (24/34) of non-attenders had attended at least two screening rounds prior to FP assessment. 75% of FP women had an imaging-only assessment with 17.5% (30/171) failing to re-attend, and 25% received a biopsy, with 7% (4/57) failing to re-attend subsequently. <br/>\ud \ud <strong>Conclusion:</strong><br/> This study is unique as it follows FP women through four consecutive screening rounds. FP non-attendance rates were considerably lower compared to the general screening population, with diagnostic work-up having limited influence. FP non-attendance may appear insignificant in comparison to total screened population, but these women are at greater risk of subsequent cancer so should be actively encouraged to re-engage with the screening programme.
