Radiation Therapy Tailored to Your Tumor

At NewYork-Presbyterian Lawrence Hospital, we have the most advanced radiation therapy plans and technology available to treat cancer, including approaches that conform to the exact shape of your tumor. You can receive radiation therapy that zeroes in on your cancer while sparing nearby healthy tissue, resulting in fewer side effects than conventional radiation therapy. Our radiation therapy team has decades of experience and expertise treating all types of cancers using these techniques.

Since many regimens of radiation therapy require you to come five days a week for your care, you'll find it helpful to receive these treatments closer to your home.

State-of-the-Art Radiation Therapy

Our radiation oncology suite houses some of the most advanced radiotherapy equipment in Westchester County. We offer the following types of radiation therapy:

  • Intensity-modulated radiation therapy (IMRT): This technique allows us to shape beams of radiation at different intensities to conform to your tumor precisely. We can tailor an infinite number of radiation beams to your tumor from many different angles at the same time, safely and quickly, while minimizing the dose to nearby normal, vital structures.
  • Image-guided radiation therapy (IGRT): IGRT combines traditional radiation treatment with a simultaneous computed tomography (CT) scan to allow for greater precision and accuracy when targeting and treating your tumor.
  • Hypofractionated ("short course") radiation therapy: This treatment regimen allows you to receive higher doses of external beam radiation over a shorter period of time — for example, breast cancer treatment over three weeks instead of five to six. This treatment plan is not an option for all people with cancer; your doctor will let you know if it is right for you.
  • Stereotactic radiosurgery: With this treatment, the total dose of radiation is given in a single session or is divided into several smaller doses given over several days. We deliver the radiation in the form of a highly focused beam applied in multiple sweeps around the tumor. We use this approach to treat some brain tumors and other solid cancers, including some lung cancers.

Simulation and Treatment Modifications

Before you begin radiation therapy, you will go through a process called simulation. During this procedure, which takes about an hour, we take a series of scans of your tumor and use the data to determine the best way to target radiation therapy to your cancer.

Once you've begun therapy, we'll periodically monitor your response to treatment to see how well your tumor is shrinking and make any necessary adjustments to your treatment plan along the way. This approach, which takes only a few extra minutes each time, ensures you are receiving truly customized treatment at each point during the course of your care.

Combined-Modality Treatment (CMT): Chemotherapy and Radiation

Since many cancers are treated by delivering radiation therapy and chemotherapy over the same period of time, our multidisciplinary team of physicians, therapists, and nurses from medical and radiation oncology work closely together. In addition to our radiation oncology suites, NewYork-Presbyterian Lawrence Hospital also has a state-of-the-art Infusion Center onsite, where we deliver chemotherapy, immunotherapy, and other infusion therapies that may be part of your treatment. Our disease management teams are essential for coordinating combined-modality treatment with radiation therapy and chemotherapy, which can both be delivered in our Cancer Center and often on the same day.
