Personal profile

Personal profile

Dr. Daly is a national leader in the field of clinical cancer genetics, and is the founder and director of one of the first cancer risk assessment and counseling programs in the country, established in 1991.

Dr. Daly is the founder and director of Fox Chase Cancer Center’s Risk Assessment Program, which is heavily grounded in research. The program has contributed to early observations regarding risk perception and risk-reducing behavior among women with a family history of breast and/or ovarian cancer, and has been instrumental in the development of state-of-the-art cancer risk counseling interventions...

Dr. Daly’s primary areas of research include the epidemiologic and genetic aspects of breast and ovarian cancer, and the translation of this information into effective cancer control approaches.

As Project Co-Leader of the Fox Chase Ovarian SPORE grant, Dr. Daly has initiated studies of ovarian cancer screening modalities, quality of life after prophylactic surgery, serum biomarkers of breast and ovarian cancer risk and developed decision-making tools for women contemplating prophylactic surgery. 

As Principal Investigator of the Philadelphia Breast Cancer Family Registry, she is collaborating with institutions worldwide to study the patterns of familial breast and ovarian cancer, gene-environment interactions, and the development of novel, genetic-based therapeutic and preventive strategies. 

She chairs the Hereditary Breast and Ovarian Cancer Risk Panel for the National Comprehensive Cancer Network (NCCN) and is a member of its Breast Cancer Screening Guidelines and Breast Cancer Prevention Guidelines Panels. 

Dr. Daly is a leader in the design of educational programs in cancer genetics and cancer risk for both high-risk individuals and for their health care providers. 

She served as the Principal Investigator of the NSABP breast cancer prevention trials (P1 and STAR). 

Dr. Daly is the Editor-in-Chief of the PDQ Cancer Genetics Board.  She has co-authored over 225 peer-reviewed publications and has served on a number of editorial boards.

Personal profile

Treatment Philosophy

I consider it an honor and a privilege to have the opportunity to accompany my patients on their cancer journey. I am allowed to witness their strength and courage, to be exposed to the devotion of their families and friends, and to become part of their lives in a very special way.

By extending this care to family members through the risk assessment program, we can work together towards the reduction of risk and prevention of cancer. I like to approach every patient encounter as a mutual learning experience. It is an opportunity for me to share with each patient the latest information about their cancer and treatment or their cancer risk, and give them the tools they need to make informed decisions.

It is also an opportunity for them to teach me something about themselves, about their lives and families, and how they cope with illness and promote their own health. I always feel both drained and enriched after a day in clinic.
