Ronald Balassanian, M.D.

Pathologist

Dr. Ronald Balassanian is a pathologist in the Fine Needle Aspiration Clinic at UCSF Medical Center at Mount Zion. He performs fine needle aspiration (FNA) biopsies, primarily on lumps or mass lesions in areas such as enlarged lymph nodes, nodules in the breast or thyroid, to help determine if a lump is benign or malignant. This procedure can yield a quick assessment, usually in a day or two. In some cases, ultrasound is used to guide the needle used to obtain a biopsy.

In his research, Balassanian studies minimally invasive diagnosis through FNA biopsy and investigates the use of molecular diagnostics to increase the value of FNA biopsy. He also studies breast cancer diagnosis, through FNA biopsy and surgical pathology.

Balassanian earned a medical degree at the University of Vermont College of Medicine in Burlington. He completed residency training in pathology and laboratory medicine, and fellowship training in surgical pathology and cytopathology, at UCSF. He is a member of the United States and Canadian Academy of Pathology, a fellow of the College of American Pathologists, and a member of the American Society of Clinical Pathology, American Society of Cytopathology and the Papanicolaou Society of Cytopathology. Balassanian is an assistant professor of pathology at UCSF.
