Memorial Sloan Kettering Sleepy Hollow offers the following services for adults with cancer.

Chemotherapy and Medical Oncology

Our Sleepy Hollow facility is home to medical oncologists who focus on particular types of cancer. We are experts in using clinical information to plan and manage treatment in ways that are tailored to your specific clinical condition.

If you need chemotherapy, biologic therapies, or intravenous medications, our infusion suite offers a calm and relaxed environment for receiving them. Our focus is on making the experience as comfortable as possible. You are welcome to bring a friend or family member to help pass the time during treatment. Snacks are also available while you are receiving care.

Radiation Therapy

Memorial Sloan Kettering Cancer Center is a leader in the use of advanced technologies to deliver radiation treatment safely and with precision.

At our Sleepy Hollow facility, we use innovative radiation therapy methods that were developed at Memorial Sloan Kettering Cancer Center. We utilize two state-of-the-art linear accelerators, advanced imaging and CT simulation, and high-speed computer-based systems to deliver radiation directly to the tumor with remarkable precision. We are experts in intensity-modulated radiation therapy (IMRT) and image-guided radiation therapy (IGRT), and use on-board imaging (OBI) to monitor and account for changes in the location of the tumor immediately before and during each treatment.

Safety is a high priority at each step of your treatment. Medical physicists are involved in every radiation procedure to ensure that the correct dose of radiation is delivered precisely where it is needed.

Hematologic Oncology

Memorial Sloan Kettering Sleepy Hollow provides consultations and treatment for patients with lymphoma, multiple myeloma, chronic leukemia, and other blood cancers. We offer clinical trials and access to Memorial Sloan Kettering’s world-class bone marrow and stem cell transplantation program.

Support Services

Memorial Sloan Kettering Sleepy Hollow provides social work and nutritional counseling services to help you cope with any emotional or practical challenges that may arise during or after treatment. We work closely with community cancer support groups and collaborate in local educational, survivorship, and palliative care programs.
