Answer:
el desarrollo de terapias hormonales ha permitido enlentecer y/o detener el crecimiento de tumores, incluyendo tumores en tejidos mamarios
Explanation:
La terapia hormonal, también conocida como terapia endócrina, es un tratamiento utilizado enlentecer y/o detener el crecimiento de células y tejidos defectuosos. La terapia hormonal se divide en dos (2) clases de acuerdo a su modo de acción en el cuerpo: 1-terapias con el objetivo de bloquear la capacidad del cuerpo para producir hormonas y 2-terapias que bloquean la función normal de las hormonas en el cuerpo. La terapia hormonal permite controlar el desarrollo de células cancerosas que se dividen formando tumores y aquellas que se desprenden del tumor para viajar a través del cuerpo formando nuevos tumores, es decir, produciendo metástasis. En cáncer de mama, la terapia hormonal posee múltiples beneficios: 1-reduce el riesgo de formación de tumores en otro tejidos mamarios, 2-previene la reaparición de células tumorales, 3-detiene el crecimiento de células tumorales y 4-reduce el tamaño de tumores previamente a la realización de una cirugía, haciendo más fácil la tarea de extirparlo. Por otra parte, diferentes metodologías desarrolladas con el objetivo de matar células tumorales mamarias también incluyen la quimioterapia, la cual usa drogas para reducir el número de células cancerosas, y la radioterapia, que consiste en el uso de altas dosis de radiación para destruir las células tumorales.
