Philosophy of Care

Cancer is not a disease that occurs in a vacuum and thus I focus not only on treating the cancer but also on assisting patients with the nutritional, social, emotional, and spiritual issues which are often ignored in modern medicine. I believe strongly in a multidisciplinary team approach to cancer including open lines of communication with both my patients and fellow physicians. Although I employ aggressive cutting edge anti-cancer treatments I am also respectful of and willing to incorporate holistic and alternative medicines into patient care. Ultimately I strive to treat each patient with the same respect and diligence I would an ailing member of my own family.

Clinical Interests

Dr. Monjazeb has a clinical focus on the treatment of gastrointestinal malignancies (including esophageal cancer), sarcoma, and central nervous system malignancies. He specializes in various radiotherapy techniques including intensity modulated radiation therapy (IMRT), image guided radiation therapy (IGRT), stereotactic body radiotherapy and high dose rate brachytherapy.

Dr. Monjazeb is a clinician scientist and participates in both clinical and basic science research projects. His basic science research is focused on understanding how the immune system can be harnessed to fight cancer and how radiotherapy can be used to promote anti-tumor immune responses.
