HPV-independent Cervical Cancers with Andreina Fernandes

In this episode of the IJGC podcast, Editor-in-Chief Dr. Pedro Ramirez, is joined by Dr. Andreina Fernandes to discuss HPV-independent Cervical Cancers. Dr. Fernandes is a Molecular Biologist, Doctor of Science, and author of “Human papillomavirus-independent cervical cancer,” the Lead Article for the January 2022 issue of IJGC. Dr. Fernandes is a Researcher of the Molecular Genetics Laboratory at the Institute of Oncology and Hematology, and Professor of the Faculty of Dentistry, at Universidad Central de Venezuela in Caracas, Venezuela.
