Age at first menstruation and clinical breast cancer screening utilization: insights from the 2021 Côte d'Ivoire demographic and health survey.

Background: There is a strong evidence showing that women who start menstruation early are at a greater risk of developing breast cancer. Recognizing that women will seek breast cancer screening when they have a high perceived risk, we hypothesized that women who experienced early menarche will be more likely to utilize clinical breast examination (CBE). Hence, we aimed to investigate the association between age at first menstruation and women's utilization of CBE in Côte d'Ivoire.
