About Jing Xi, MD, MPH
Dr. Jing Xi is a board-certified medical oncologist who joined Rocky Mountain Cancer Centers in 2022. Her clinical practice is dedicated to the care of patients with breast cancer. Her clinical and research interests are in molecular mechanisms of resistance to targeted therapy in metastatic breast cancer. She has contributed extensively to breast cancer research, including authoring and co-authoring peer-reviewed journal articles, oncology conference abstracts, and oncology book chapters. In addition to being actively involved in clinical research, Dr. Xi remains up to date on the most recent treatment advancements and cutting-edge therapies.
Dr. Xi’s goal at each clinic visit is to help navigate the cancer care journey together with her patients by guiding patients through their diagnosis and providing clear and comprehensive education on treatment options, including the latest clinical trials. This is to make sure that her patients can feel confident making informed decisions about their care.
Dr. Xi is an active member of several weekly tumor boards and multi-disciplinary clinics, where she works closely with other cancer specialists including breast imaging, surgical oncology, radiation oncology, and plastic surgery, to review patient cases, share knowledge, and determine the best possible treatment for each patient. This collaborative approach helps to deliver the highest quality of cancer care.
As a women’s health specialist, Dr. Xi also specializes in treating gynecologic cancers. As a board-certified hematologist, Dr. Xi also treats non-cancerous (benign) blood disorders including bleeding disorders, clotting disorders, and iron deficiency anemia.

Patient Care Philosophy
I am dedicated to delivering personalized care to improve patient outcomes and quality of life. I offer a tailored therapeutic approach based on each patient’s specific tumor biology and side-effect profile, which yields better treatment response and tolerability. I integrate the latest advances in science into patient care. I take care of my patients as a whole person, including not only their physical health, but also emotional health, and in some patients, reproductive health during their treatment with chemotherapy and endocrine therapy.
