10% of breast cancers in Spain are already diagnosed in patients under 40 years old. However, all this, Vidal points out, does not explain why it appears in such young patients: "Below 30 years old, cases are very infrequent; the vast majority of the incidence in young people is grouped between 30 and 40 years old, with a very clear peak between 35 and 40 years old." #CáncerDeMama #InvestigaciónOncológica #DíaMundialDelCáncerDeMama (translated)
