Radiation Therapy

Radiation therapy is the use of high-energy x-rays or radioactive materials to kill cancer cells. This radiation injures the cancer cells so that they can no longer continue to divide and multiply.  Each treatment causes more cells to die, reducing the size of the cancerous tumor. Radiation therapy incorporates various techniques, including external electron or photon beams or internal radiation.  The treatment is odorless and invisible.  Your radiation oncologist and medical oncologist will work together closely to determine if your treatment will include radiation therapy. 

Our radiation oncology team uses the most advanced treatment planning systems and state-of-the-art technology to deliver internal and external radiation to cancerous cells, with the intent of eradicating the existing disease and preventing further growth. Whether your treatment plan includes Intensity Modulated Radiation Therapy (IMRT) or 3-D Radiation Therapy, you can receive your radiation therapy right here in our offices on an outpatient basis.  Intensity Modulated Radiation Therapy (IMRT) is an advanced form of radiation therapy allowing the radiation oncologist to precisely target tumors by using Computed Tomography (CT) to build three-dimensional images to accurately target treatment using tightly focused radiation beams of varying intensity. IMRT allows the radiation oncologist to maximize tumor dosage while minimizing radiation exposure to nearby uninvolved tissues and thereby reducing the occurrence of treatment related side effects.
