Dr Knaul talks to ecancertv about our participation at the "Mujer Jóven y Cancer de Mama: Retos y Respuestas" seminar and how important it is to help with the dissemination from this event. She discusses the importance of international collaboration in achieving a greater understanding of the epidemiology of breast cancer in young women and highlights how this conference is helping to dispel the myth that breast cancer is only a disease of the older woman.
