Get to Know Me
I am a board-certified medical oncologist who specializes in the identification and management of individuals who have inherited an increased risk for cancer. I concentrate on helping men and women with cancer incorporate genetic information into their treatment plan. For those who are at increased risk, but have not been diagnosed, I work to develop a plan that will help them either prevent the development of cancer, or limit its impact if it occurs.
Along the same lines, my research focus has studied the best ways to use genetic information to improve the outcomes of those with or at risk for hereditary cancers of all types.

Consistent with the goals I pursue in my clinical genetics work, my oncology practice is weighted toward the management of young women with breast cancer, especially hereditary breast cancer. As part of that practice, I participate in the development of new treatments, such as PARP inhibitors, which may be particularly useful for this group of women. Finally, I also maintain a separate practice where I coordinate screening for women with mutations in BRCA1 or BRCA2.
A breast medical oncologist is a cancer doctor who specializes in breast cancer.
A clinical geneticist is a scientist with special training in diagnosing and treating genetic conditions. They can help explain your risk of getting a genetic condition that is passed on from parents to children.

The professionalism and expertise of the team at MSK is very valuable. The wait time is really too much.
The staff and Dr Robinson was great to meet.
Dr Robson knew my case history and made recommendations I'm certain will have positive treatment outcomes. This appointment was our initial meeting.
I've never felt as heard by a Doctor as much as I was by Dr. Robson. He understood my mindset abt my diagnosis, and I felt very supported. I couldn't imagine there being a better Oncologist for my particular situation than him. I feel truly blessed.
I have been with MSK since my diagnosis of breast cancer - the experience has been phenomenal and care has been seamless and just about perfect
