Heather L. McArthur, MD, MPH

About Me

I am a medical oncologist with a clinical practice dedicated to the care of patients with breast cancer. My research activities are focused on innovations in the diagnosis and treatment of breast cancer. For example, I am currently collaborating with investigators at Cold Spring Harbor Laboratory to explore genetic markers in breast cancer by a developing technique called comparative genomic hybridization (CGH). It is anticipated that improved accuracy in the identification of certain genetic markers will enable physicians to make treatment recommendations that are tailored to individuals and their cancer, thereby producing better outcomes for patients.

Clinical Trials

Research is integral to our mission at Memorial Sloan Kettering, and clinical trials help us discover better forms of patient care and treatment. For you, this could mean access to a new therapy or therapy combination. Click to see a list of the trials I’m currently leading.


Most major health insurers offer plans that include MSK as one of their in-network providers. If MSK is in-network, it means all our doctors are too. Medicaid and New York State Medicare also provide benefits for care at MSK.
