<div>Hola, somos Daniela, Guillermo y Diana, hijos de Guillermo de la Sierra.
</div>
<div><br />
</div>
<div>Queremos contarles nuestra historia, o más bien la historia de nuestro papá , y pedirles sus oraciones y apoyo para que ocurra un milagro. El 5 de junio de 2026, mediante una resonancia le encontraron un tumor en la cabeza a nuestro padre, después de muchos médicos, estudios y una biopsia, le diagnosticaron un tipo de tumor cerebral maligno llamado glioblastoma.
</div>
<div><br />
</div>
<div>A pesar de contar con un seguro de gastos médicos mayores y de estar actualmente con un tratamiento convencional de quimioterapia y radioterapia, los doctores nos han dado una esperanza de vida muy corta. Por eso, hemos estado buscando terapias integrativas que puedan acompañar el tratamiento de nuestro padre, dándole una mejor calidad de vida y una esperanza de vida mayor.
</div>
<div>Actualmente, estamos llevando a cabo un tratamiento con células dendríticas con el Centro Médico Nacional de Biología molecular en la ciudad de Puebla. Queremos incorporar a su tratamiento terapias de oncothermia en la Ciudad de México y ver si existe la posibilidad de que participe en los ensayos de terapia Oncomagnética. Todos estos tratamientos, tienen costos extra, que el seguro no cubre y exceden nuestra capacidad económica, por tal motivo, recurrimos a este medio de apoyo para sumar esfuerzos e intentar lograr una meta con el apoyo de ustedes. Estamos convencidos de que solo haciendo cosas diferentes podemos cambiar el resultado de esta enfermedad.
</div>
<div><br />
</div>
<div>Cualquier aportación, por pequeña que sea, será un gran alivio para nosotros y para la lucha de nuestro papá. Muchas gracias de corazón.
</div>
<div><br />
</div>
<div>En caso de que su apoyo económico no sea posible, contamos con sus oraciones.
</div>

</div>
<div>Hello, we are Daniela, Guillermo, and Diana—Guillermo de la Sierra’s children.
</div>
<div><br />
</div>
<div>We want to share our story—or rather, our dad’s story—with you and ask for your prayers and support so that a miracle might happen. On June 5, 2026, an MRI revealed a tumor in our father's head; after consulting many doctors, undergoing numerous tests, and having a biopsy, he was diagnosed with a malignant brain tumor known as glioblastoma.
</div>
<div><br />
</div>
<div>Despite having major medical insurance and currently undergoing conventional chemotherapy and radiation, the doctors have given us a very grim prognosis regarding his life expectancy. That is why we have been seeking integrative therapies to complement his treatment, aiming to improve his quality of life and extend his time with us.
</div>
<div>We are currently pursuing dendritic cell therapy with the National Medical Center for Molecular Biology in Puebla. We also want to incorporate oncothermia therapy in Mexico City into his treatment plan and explore the possibility of his participation in oncomagnetic therapy trials. All these treatments entail additional costs that are not covered by insurance and exceed our financial means; therefore, we are turning to this platform to rally support and reach our goal with your help. We are convinced that only by trying different approaches can we change the outcome of this disease.
</div>
<div><br />
</div>
<div>Any contribution, no matter how small, will be a tremendous help to us and to our dad in his fight. Thank you from the bottom of our hearts.
</div>
<div><br />
</div>
<div>If you are unable to provide financial support, we would deeply appreciate your prayers.
</div>
<div><br />
</div>
<div>Bonjour, nous sommes Daniela, Guillermo et Diana, les enfants de Guillermo de la Sierra.
</div>
<div><br />
</div>
<div>Nous souhaitons vous raconter notre histoire, ou plutôt celle de notre père, et vous demander vos prières ainsi que votre soutien afin qu’un miracle puisse se produire.
</div>
<div><br />
</div>
<div>Le 5 juin 2026, une IRM a révélé la présence d’une tumeur au cerveau chez notre père. Après de nombreuses consultations médicales, plusieurs examens et une biopsie, les médecins lui ont diagnostiqué un type de tumeur cérébrale maligne appelé glioblastome.
</div>
<div><br />
</div>
<div>Bien qu’il bénéficie d’une assurance de frais médicaux majeurs et qu’il suive actuellement un traitement conventionnel de chimiothérapie et de radiothérapie, les médecins nous ont annoncé une espérance de vie très courte. C’est pourquoi nous recherchons des thérapies intégratives pouvant accompagner son traitement, afin de lui offrir une meilleure qualité de vie et davantage d’espoir.
</div>
<div><br />
</div>
<div>Actuellement, nous réalisons un traitement à base de cellules dendritiques avec le Centre Médical National de Biologie Moléculaire, dans la ville de Puebla. Nous souhaitons également intégrer à son protocole des séances d’oncothermie à Mexico et étudier la possibilité de sa participation à des essais de thérapie oncomagnétique.
</div>
<div><br />
</div>
<div>Tous ces traitements entraînent des coûts supplémentaires que l’assurance ne couvre pas et qui dépassent nos capacités financières. C’est la raison pour laquelle nous faisons appel à votre générosité afin d’unir nos forces et tenter d’atteindre cet objectif avec votre aide. Nous sommes convaincus que c’est en explorant de nouvelles approches que nous pouvons espérer changer l’évolution de cette maladie.
</div>
<div><br />
</div>
<div>Toute contribution, même modeste, représentera un immense soulagement pour notre famille et pour le combat de notre père.
</div>
<div><br />
</div>
<div>Merci du fond du cœur.
</div>
<div><br />
</div>
<div>Si un soutien financier n’est pas possible, nous vous serions également très reconnaissants de nous porter dans vos prières.
</div>
<div><br />
</div>
<div><br />
</div>
