About Me

What I Do at MSK
  • Director, Rare Breast Cancer Program, Department of Surgery
Get To Know Me

I am a breast surgeon who treats benign (noncancerous) and malignant (cancerous) breast diseases. I am experienced in all the latest surgical approaches for all types of procedures, including:

  • Axillary surgery to access the lymph nodes in the armpit area
  • Oncoplastic breast surgery, such as nipple sparing mastectomy, and breast conservation methods. These procedures can help preserve the physical appearance of the natural breast after cancer treatment.

When patients first meet with me, they are often scared about what lies ahead. They have many questions about how their diagnosis and treatment will affect their quality of life. I take the time to clearly answer their questions, understand their concerns, and explain their options. My goal is to help them make an informed decision about the next steps in their care. I want them to leave my office with an understanding of their disease and a clear treatment plan.

At Memorial Sloan Kettering Cancer Center (MSK), I work as part of a team that includes experts from:

  • Medical oncology
  • Pathology
  • Plastic surgery
  • Psychology
  • Radiation oncology
  • Radiology

Our goal is to deliver the highest quality of care that offers the best possible result. We start by creating a treatment plan that meets each patient’s personal needs and preferences.

I also have a special interest in studying rare types of breast cancer, such as metaplastic breast cancer and phyllodes tumors. These rare tumors account for approximately 1% of all breast cancers. Their biology is different from that of more common breast cancers, like ductal or lobular cancer. However, there is a lack of research data in this area. As a result, these tumors are treated based on guidance from general breast cancer guidelines.

I also co-lead MSK’s Rare Breast Cancer Program with my colleague, Nour Abuhadra. Our mission is to support people with rare breast tumors throughout their cancer journey, and to advance research in the field.

My Role at MSK
