121 Background: More than 362,000 female cancer survivors under 40 years old live in the US. Research consistently shows no increased cancer risk among offspring of cancer survivors in the absence of a hereditary cancer. Still survivors voice concerns over the health of future children. This analysis explores young adult female cancer survivors’ (YAFCS) perceptions of genetic cancer risk and related reproductive concerns. Methods: Eligible females were aged 18-35, at least one year post-treatment. Participants were recruited using social media posts from 17 young adult cancer advocacy groups and directed to an anonymous web-based survey that included the Reproductive Concerns after Cancer Scale (RCACS), with a 3-item “Concerns about Future Child Health” subscale. Results: 346 YAFCS completed the full survey, and based on logic-based branching, 192 respondents could have completed the RCACS: 177 (92%) completed the entire scale and 187 (97%) completed the child’s health subscale. Mean RCACS score was 58.5 (sd = 11.6; range 22-86); mean child’s health score was 11.3 (sd = 3.3; range 3-15), with a negative skew. At the item-level, 65% of the sample worried about passing along cancer risk to offspring; 71% worried about family health history affecting future children; and 60% were afraid their children would have a high chance of getting cancer. RCACS and child’s health subscale scores did not vary by age, race, education, income, or diagnosis. Further, mean scores did not vary between survivors of family cancer syndromes (breast, ovarian, colorectal) and those with other diagnoses (RCACS: t = 1.4, df = 175, p = .14; child’s health: t = 0.02, df = 185, p = .99). Conclusions: Despite studies showing minimal genetic cancer risk in offspring of survivors, many YAFCS have concerns about the health of future children. This may be related to mistaken beliefs that genetic mutations within tumor cells are transmissible or unawareness of availability of pre-implantation genetic diagnosis for embryo selection in those with transmissible genetic mutations. There is a need to educate patients about these issues to enable them to make family building choices based on accurate information about genetic risk.
