Get to Know Me

I am a medical oncologist with a practice devoted to treating people with breast cancer.

I chose to focus on oncology because cancer is an enormous human problem and I wanted to help people who are affected by it. It has been my long-term desire to translate scientific discoveries into ways to treat disease and alleviate suffering.

My laboratory and clinical research both focus on developing new treatment strategies against breast cancers that become resistant to standard treatments. I research the molecular factors that play a role in resistance in order to identify targets that may lead to new treatments.

I am fortunate to work with an exceptional team of physicians and scientists who share my goal of eradicating breast cancer. Together, we are exploring several exciting ways of treating this disease.

Our research includes novel therapies that target the biological factors that make cancers grow. We are studying new inhibitors that block pathways that facilitate breast cancer growth or drug resistance. We are also investigating treatments that can deliver therapy specifically to cancer cells as well as antibody drug conjugates — hybrid drugs that make use of immunotherapy and chemotherapy — which will enable more targeted therapy.

What I Do at MSK

I'm a breast medical oncologist, which is a cancer doctor who specializes in breast cancer.

Dr Chandarlapaty is a great doctor. He explains everything. He listens to my questions and he answers them. He has been taking care of me and my cancer for almost 5 years.

Apr 11, 2025

When I meet someone who develops breast cancer, I will tell them that Dr. Sarat Chandarlapaty is amazing. He is someone you could trust with your care. he pays attention, listens and doesn't convince to do something one way or another, but DEVELOPS a Plan of treatment based on who you are and where you are in your journey. He is not NOT a one protocol fits all. He gives you the pros and the cons. If you want someone who is analytical, yet doesn't leave you out ofthe journey you are on, then he is your man. If there was a way to rate him higher than a 10 out of 10, he deserves it. He may not come across as mushy and warm. He may seem to say very little at first. But once you develop a relationship, you quickly find he is on YOUR side.

Apr 4, 2025

Dr, Chandarlapaty is a terrific breast cancer oncologist. He is always aware of all the changes in my health and listens for my input. He is on top of the latest pharma innovations and approvals and is a very lovely person.

Apr 4, 2025

I wish every doctor I had was like Dr. Chandarlapaty and his team.

Apr 4, 2025

Both the reception desk and provider were both attentive and courteous to my feelings
