Most patients that get radiation therapy, receive a very carefully administered dose and delivery of the therapy. While there can be some difficulty with this therapy, but it is a key component of the successful breast cancer treatment. However, some patients with particular tumor characteristics can receive a very localize radiation dose that is administer right to the location of the primary tumor. The device that is utilized to complete this treatment is called a Mammocyte. Dr. Brown has been on the cutting edge of this technology and founded the Accelerated Partial Breast Irradiation Program (Mammocyte) at Maury Regional Medical Center about 15 years ago.
