Breast Cancer Treatment: particular interest in the treatment of triple-negative and hereditary breast cancers; Breast, Ovary, and Prostate Cancer Risk Assessment

Treatment Philosophy

My philosophy in taking care of my patients is to spend as much time as possible listening to them. This allows me to know exactly what their fears and concerns are. I believe in working with our patients as a team to design the best plan of care for them,  and when appropriate for their families if we identify a susceptibility to developing cancer in that family.

Lab Overview

The Risk Assessment Program at Fox Chase looks at your personal and possible inherited genetic factors that may put patients at higher possibility for getting cancer.  Our team comprehensively examines the risk of an individual for different cancer types, including — but not limited to — breast cancer, ovarian cancer, gastrointestinal cancers, prostate cancer, and melanoma. Such information is helpful in order to understand the chances of getting cancer and decrease the likelihood of cancer or to detect cancer early. The Department of Clinical Genetics is built on the success of Fox Chase's Margaret Dyson Family Risk Assessment Program (now Risk Assessment Program), which Dr. Mary Daly began in 1991. A high-risk screening clinic was developed for individuals with a family history of breast or ovarian cancer.

As a member of the Breast Cancer Research team at Fox Chase, we offer our patients emerging therapies for breast cancer where patients have the opportunity to enroll in national clinical trials unique to Fox Chase that target breast cancer. I am interested in the design and implementation of trials focused on the development of those new therapies. In collaboration with other scientists, we work on understanding the biology of breast cancer through translational studies. My particular interest is in tumor microenvironment and immunotherapy.

Tracy Gatto

  • Breast Cancer

In 2011 at the age of 28, Tracy Gatto learned she had breast cancer after she discovered a lump in her breast. She sought a second opinion from a specialist at Fox Chase Cancer Center and immediately felt that was where she wanted to seek treatment. Tracy underwent chemotherapy, followed by surgery and reconstruction. Because of the BRCA1 genetic mutuation she most likely inherited from her father, Tracy had increased risk of ovarian cancer. She worked with the Risk Assessment Program, where she was referred to a surgical gynecologist to discuss the possibility of undergoing a prophylactic oophorectomy to remove her ovaries. Today, Tracy is doing well and even took part in Paws for the Cause, an annual dog walk and fundraiser hosted by Fox Chase, to give back. "It really takes a special person to work at Fox Chase. Everyone I met had a smile on their face and was incredibly positive," she said. "As a receptionist, I knew it can be a struggle to stay positive all day long. It’s hard to make cancer a positive experience, but I never left feeling discouraged."

    Dr Obeid is my Oncologist and this visit was an Annual follow-up from Breast Surgery. [...] If anything goes wrong with my breast, then I would get in touch with Dr Obeid. I find Dr Obeid extremely smart and like his manner.
