Impact of fertility preservation on risk of recurrence and odds of pregnancy among young women with breast cancer

The safety of fertility preservation (FP) requiring ovarian stimulation among young women with breast cancer is not clear. A study in British Columbia (Canada) found that among young women with stage I-III breast cancer FP, with median 4.1 year follow-up, did not impact invasive breast cancer-free survival (FP versus non-FP group: HR 1.006; p=0.988) or overall survival (HR 0.789; p=0.725) and was associated with higher odds of conceiving at least once (OR 3.024; p=0.008).
