Cáncer de mama bilateral sincrónico en el varón. Descripción de un caso y revisión de la bibliografía

Male breast cancer is a rare entity, accounting for less than 1% of all diagnosed breast cancers. Risk factors include advanced age, obesity, testicular and liver diseases, and the presence of germline BRCA2 mutations. Even rarer is the occurrence of synchronous bilateral breast tumors, defined as tumors diagnosed within 12 months of the initial breast cancer. Due to its extreme rarity, few cases have been published in recent years, with most not referencing mutation studies. Greater awareness of the disease would prevent delays in both diagnosis and treatment.
