If you have cancer and need radiation therapy—also known as radiation oncology—Mount Sinai-Union Square offers you the best care with a personal approach. We provide radiation oncology treatments for many cancers in our convenient location using state-of-the-art technology.

Normally, you receive your treatment as an outpatient, in short daily visits, which can minimize disruptions to your daily life. You can take part in our many supportive services to add a holistic experience.

Radiation therapy is used in a variety of ways depending on your diagnosis:

• To cure cancers without surgery
• To shrink a tumor before surgery
• To treat cancer cells remaining after surgery
• For palliative care, when a cure is not possible. Palliative radiation therapy can shrink a tumor and relieve pain and other symptoms.

Radiation therapy is often combined with chemotherapy and/or surgery. Our radiation oncologists work closely with other specialists to give you optimal care. Our doctors are also on the faculty of the Icahn School of Medicine at Mount Sinai, one of the nation’s leading medical schools, which means you have the benefit of the latest research and clinical trials.
