Guidance on physical activity from cancer survivorship to pregnancy: a scoping review.

Background: Improvements in cancer survival have resulted in a growing number of women of reproductive age who plan pregnancy or become pregnant after cancer. Physical activity is widely recommended during pregnancy and across the cancer survivorship continuum; however, there is currently no existing guidance adequately addressing women who fall at the intersection of these contexts. This scoping review was aimed at mapping existing guidance on physical activity during pregnancy and cancer survivorship, and to identify gaps relevant to women planning pregnancy or who become pregnant after cancer treatment. Materials and methods: A scoping review of clinical practice guidelines, position statements and consensus documents addressing physical activity during preconception, pregnancy, postpartum or cancer survivorship was conducted. Sources were identified through database searches. Data were presented according to population (preconception, pregnancy, postpartum, cancer survivorship, pregnancy after cancer) and recommendation domains, including exercise prescription, safety, cancer treatment-related considerations, monitoring and progression, and implementation pathways. Results: A total of Conclusion: Although physical activity guidance is well established for pregnancy and cancer survivorship independently, recommendations remain siloed and do not address the needs of women navigating pregnancy after cancer. Integrated, interdisciplinary guidance is needed to support safe, individualised physical activity participation in this growing population.
