My clinical research efforts include studies comparing the effectiveness of radiation to observation in patients with low-risk duct carcinoma in situ. I have also developed a novel treatment for elderly women, using single-dose intra-operative radiation therapy, and continue to refine the use of radiation therapy with patients in the prone, or face-down, position, in an effort to improve the long-term cosmetic outcomes and to protect normal tissue in women with breast cancer.
I serve on the breast committee for the National Comprehensive Cancer Network (NCCN) guidelines panel. I am a former chair of the Breast Program Committee for the American Society of Clinical Oncology (ASCO) and former Chairman of the Breast Committee for the Radiation Therapy Oncology Group (RTOG) Cooperative Group. I have served on many consensus panels, and have written extensively on both breast and eye cancers.
