Objective: Fertility and childbearing issues are the major quality of life concerns among young breast cancer survivors. Practical approaches are needed to convey reproductive health information. The Fertility and Cancer Project (FCP) is a dedicated research project that provides online reproductive health and fertility education. We report FCP participants' (a) changes in mood and functioning and (b) changes in knowledge of fertility and cancer from baseline to 6-month follow-up. Methods: Participants completed five self-report baseline measures, accessed FCP content and participated in online discussions. At 6 months post FCP study entry, participants were asked to complete follow-up self-reports. Results: One hundred and six breast cancer survivors from 8 countries participated in the FCP. Mean age at diagnosis was 34.3 years; mean time since diagnosis was 22 months. Significant change was detected in improved physical functioning (p=0.019) and social functioning (p=0.02). Significant changes were also noted in improved fertility knowledge (p=0.011). Conclusion: Preliminary evidence shows that young breast cancer survivors derive improved mood and knowledge benefit from FCP participation. Internet-based approach may be a viable format for engaging this population of cancer survivors. © 2009 John Wiley & Sons, Ltd.
