[Specificities of breast cancer management in AYAs]

Breast cancer in adolescents and young adults (AYAs) is a rare event but requires a well-structured and tailored approach for this specific population. Oncogenetic and oncofertility consultations are essential at the time of breast cancer diagnosis in an AYA. Therapeutic management follows breast cancer guidelines, with particular attention to the risks of long-term side effects, potential constitutional genetic mutations, and specific considerations regarding hormone therapy. The number of adults who have survived cancer during childhood or adolescence/young adulthood increases each year. The morbidity associated with prior treatments and the risk of secondary cancers create needs for care and follow-up, which must be organized, anticipated, and adapted.
