About Me
Daniel R. Dickstein, MD, is an Assistant Professor of Radiation Oncology at the Icahn School of Medicine at Mount Sinai in New York City. He specializes in prostate cancer and sexual health, with particular expertise in the treatment of gay and bisexual men with prostate cancer.
His commitment to improving prostate cancer care for gay and bisexual men began when a patient asked how treatment might impact receptive anal intercourse. In prostate cancer care, conversations about sexual health almost always focus on erections and heterosexual intercourse—where a wealth of information already exists. For this patient’s question, however, there were no answers.
Determined to change that, Dr. Dickstein set out to build the evidence himself. He received an American Society of Clinical Oncology (ASCO) Young Investigator Award and has since published multiple high-impact papers, including the first studies demonstrating that prostate cancer treatments affect sexual health differently in gay and bisexual men depending on their preferred sexual behavior.
He has presented this work in invited lectures in Washington, DC, Seattle, and Vienna. He serves on the American Radium Society’s Genitourinary Appropriate Use Criteria Committee and on the advisory board for Nature Reviews Urology. What began as an effort to answer one patient’s question has grown into an evidence-based clinical practice where patients—gay, bisexual, and heterosexual alike—can discuss their sexual health concerns openly, safely, and without judgment.

Research
My research focuses on improving sexual health outcomes after cancer treatment, with particular emphasis on receptive anal intercourse and gay and bisexual men with prostate and anal cancers. I study how treatments such as surgery, radiation, and systemic therapies affect the anatomy and physiology of sexual function and pleasure. By generating evidence on how different treatments impact sexual function across sexual behaviors, my goal is to help oncologists tailor treatment recommendations and design interventions that preserve pleasure while minimizing dysfunction.

Industry Relationships
Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device, biotechnology companies, and other outside entities to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their outside financial relationships.
