Dr. Joshua G. Cohen is a board certified gynecologic oncologist with specialized training in gynecologic cancer treatment as well as clinical care and research. He offers a comprehensive and compassionate multidisciplinary approach to the treatment of gynecological malignancies including pre-invasive, invasive and advanced-stage gynecologic cancers. He has completed a fellowship in the treatment of women with gynecologic cancers including patients at high risk for ovarian and uterine cancers because of genetic mutations or strong family history, and of unknown etiology and concern for possible malignancy or difficult resection. Dr. Cohen is an expert in tumor cytoreduction and in the use of robotic surgery — including the state-of-the-art da Vinci® surgical system—and advanced laparoscopic procedures that reduce the need for open, more invasive surgical techniques for cancer care. Dr. Cohen has received teaching awards for his efforts in gynecologic surgery education and serves as the UCLA Gynecologic Oncology Fellowship Director. Dr. Cohen is a Fellow in the American College of Obstetrics and Gynecology and a Fellow in the American College of Surgeons.
He has distinguished himself in gynecologic cancer research and has completed the Clinical Research Training Program at the National Institutes of Health as well as the Clinical and Translational Science Institute certificate program at the David Geffen School of Medicine at UCLA. His research interests include the treatment of recurrent ovarian cancer and patient centered outcomes in gynecologic oncology. He serves patients in the greater Los Angeles area with offices in Westlake Village and Westwood offering a full range of oncology services and providing access to specialized research, clinical trials and diagnostic services.
