Dr. Anatolio Cruz is a clinical professor at the UT Health Science Center San Antonio and was the school’s first chief of surgical oncology. He received his surgical specialty training at the University of Minnesota. Dr. Cruz recently moved to semi-retired status after 35 years with the university. Dr. Cruz was the principal investigator for the national surgical adjuvant breast and bowel project at the UT Health Science Center, and he is helping prove that lumpectomy or segmental mastectomy is as effective as total mastectomy in cure rates and is less mutilating. He also was instrumental in promoting the blue dye-radioisotope sentinel node biopsy procedure on lymph nodes in a patient's axilla, which is now being widely tested throughout the United States and Canada.
