The Departments of Radiation Oncology at Continuum Cancer Centers of New York are recognized among the largest and most sophisticated in the country. Our world-renowned, highly skilled specialists and innovative technology attracts patients from around the world.
Radiation Oncology at Beth Israel Medical Center and Mount Sinai St. Luke's and Mount Sinai Roosevelt Hospitals is celebrated as a premier program due to our comprehensive, multidisciplinary approach to care. To provide patients with the individualized attention they need, our staff is experienced in the most advanced approaches to treatment. In addition, we offer technologically superior facilities to provide the best care possible.
Our patients often receive other treatments such as chemotherapy, hormone therapy or surgery as well as radiation therapy. To ensure the best possible outcome, this multi-disciplinary approach requires collaboration and coordination among the specialists on a patient's treatment team. Therefore, during your first visit you will meet with your radiation oncologist and a nurse practitioner. Your radiation oncologist may consult with any other specialists as necessary before your treatment begins to determine the best course of action. In addition, other members of the Cancer Support Services Program may be brought in to better help you successfully manage your treatment.
The major goal of radiation therapy is to maximize cure while maintaining optimal organ function and quality of life. Because each patient's case presents unique challenges and requires individual attention, we urge you to consult your radiation oncologist about which treatment plan is best for you. It is extremely important to seek out an expert team of physicians who specialize in your type of cancer to ensure optimal outcome.

External Beam Radiation Therapy
External beam radiation therapy involves a series of daily outpatient treatments to accurately deliver radiation to the breast.
Painless radiation treatments are delivered in a series of daily sessions. Each treatment will last less than 30 minutes, Monday through Friday, for five to seven weeks.
The usual course of radiation treats only the breast, although treatment of the lymph nodes around the collarbone or the underarm area is sometimes needed.
3-dimensional conformal radiotherapy (3D-CRT) combines multiple radiation treatment fields to deliver very precise doses of radiation to the breast and spare surrounding normal tissue.
Intensity modulated radiation therapy (IMRT) is a form of 3D-CRT that further modifies the radiation by varying the intensity of the radiation beams. It is currently being studied for treating breast cancer.
Side effects might include skin irritation, like a mild to moderate sunburn, mild to moderate breast swelling and fatigue.
Partial Breast Irradiation
Doctors are studying ways to deliver radiation to only part of the breast.
Available in a few clinics for a very select group of patients, these techniques are used after a lumpectomy to deliver radiation to the tumor site rather than the entire breast.
Breast brachytherapy involves placing flexible plastic tubes called catheters or a balloon into the breast. Over one to five days, the catheters or the balloon are connected to a brachytherapy machine so high doses of radiation can treat the nearby breast tissue.
Other techniques include 3-D conformal partial breast irradiation and intra-operative radiation therapy (IORT).
The long-term results of these techniques are still being studied. Talk with your radiation oncologist if you would like more information.
After Mastectomy Radiation
In cases where the breast is surgically removed, your doctor may suggest radiation therapy for the chest wall and nearby lymph node areas.
Whether or not radiation therapy should be used after removal of the breast depends on several factors, including the number of lymph nodes involved, tumor size and surgical margins.
