Equipo de Ciencia & Vida analizó 700 muestras de pacientes y descubrió que la rigidez del tejido mamario transforma células inmunes en agentes dañinos del ADN. El estudio resuelve pregunta de décadas: por qué mujeres con tejido mamario denso tienen mayor riesgo de cáncer, pasando de asociación estadística a explicación molecular.
