Carolyn Mary Kaelin, a surgical oncologist in the Women’s Cancers Program at Dana-Farber and director of the Breast Clinic at Brigham and Women’s Hospital, died July 28, 2015, surrounded by loved ones. Kaelin was 54.

Kaelin graduated from Smith College and Johns Hopkins School of Medicine. She earned her master’s degree from the Harvard School of Public Health. At 34, she became the founding director of the Comprehensive Breast Health Center at BWH, at that time the youngest woman singled out for a job of this caliber at a major Harvard teaching hospital.

Also active in research, she focused on how doctors and patients make medical decisions and on quality-of-life issues for breast cancer survivors, particularly the role of exercise. In 2001, Newsweek featured her as one of “15 Women of the New Century.”
