Get to Know Me
I am a board-certified medical oncologist whose clinical practice is dedicated exclusively to the care of patients with all stages of breast cancer. I am part of a large, multidisciplinary team of devoted specialists who share my goal of providing exceptional care to patients fighting breast cancer. Through my research activities, I work to develop new therapeutic options for the treatment of breast cancer and to ultimately eradicate this disease.

My research has centered on the use of novel, targeted therapies for the treatment of triple negative breast cancer (TNBC). Currently, I am the lead investigator for a multicenter trial studying the use of androgen receptor inhibition for patients with advanced TNBC. I have investigated numerous other targets for treatment of this subtype of breast cancer, including src and PARP, and have collaborated to develop biologic predictors of response to conventional therapies such as platinum. I have also had a special interest in optimizing drug delivery schedules to minimize side effects of treatment while maximizing its benefits.
I have received grant support for my work from the Breast Cancer Alliance and the Translational Breast Cancer Research Consortium (TBCRC) — a nationwide panel of centers of excellence in breast cancer medicine — where I also serve on the Triple Negative Breast Cancer working group panel. I have lectured internationally and presented our research findings at forums including the annual San Antonio Breast Cancer Symposium and the annual meeting of the American Society of Clinical Oncology (ASCO). I am a member of the New York Metropolitan Breast Cancer Group and serve on the editorial board of the European Journal of Clinical & Medical Oncology. Additionally, I am an ad hoc reviewer for several clinical journals and have published in scientific journals including the Journal of Clinical Oncology and Clinical Cancer Research.
I am committed to providing compassionate care to my patients as they undergo treatment for their breast cancer.

Dr. Traina and Dr. Ross are beyond excellent. The entire staff from security to front desk to techs, nurses to doctors were stupendous.
Dr. Traina was kind, understanding and Sympathetic to my situation. Loved her positive attitude and willingness to communicate with my daughters.
The staff was extremely friendly and the Dr was positive and informative
It is always a pleasure for me and my husband to go to my appointments at the Breast Center- everyone from the security officer in the lobby, to the blood lab staff, to my wonderful doctor and her staff, and the nurses giving infusions are welcoming, happy to answer questions, and efficient at their work. Dr. Tiffany Traina and her NP Bryn Vandermark are thorough in asking me questions about my daily health and in explaining my disease and treatment options. I am so grateful for moving to MSK after being diagnosed at another NYC cancer center where my doctor seemed rushed and harried.
Dr. Traina was very informative and professional and I plan to use her and her team for my treatment and we'll be talking with her this week about that along with the surgeon that she works with, I guess they call him Dr. LP. And so that's what I have to say. Thanks for the call tonight.
