A breast cancer diagnosis is a critical event with a potentially traumatic nature. In recent years there has been an increase of this illness in women aged under-fifty, a group of particular scientific interest. In this article the authors review the recent scientific literature on psychological impact of breast cancer experiences in under-50 women. Our results highlight three trajectories: clinical psychological risks; feminine-specific concerns; resources between individual and relational aspects. This overview illustrates the complexity of the effects of breast cancer in under-50women allowing to think about theoretical and psychosocial models to provide support for under-50 women during the illness experience.
