Radiation therapy is a very effective tool for controlling certain types of cancer. It may be used alone or in combination with other forms of treatment such as surgery and chemotherapy. The equipment used to administer radiation treatment is called a linear accelerator. This machine delivers a high-energy beam, in a precisely controlled manner, directly to the tumor while minimizing damage to the surrounding tissues. Upstate Veterinary Specialists has joined with Dr. William Ratterree who is trained in both medical and radiation oncology to provide the ultimate in care for pets receiving radiation therapy. Using live video communication, our medical oncologists and surgeons in Greenville consult with Dr. Ratterree to determine optimal treatment for each patient’s tumor.
If it is determined that radiation therapy will be helpful for your pet, precise positioning of your pet for radiation treatments is determined and documented using CAT scans, radiographs, and digital photography. Once this information is collected, sophisticated computer programming is used to generate a three-dimensional plan for administering radiation to your pet’s tumor. Radiation treatment doses are given in intervals, rather than a single large dose, to allow for repair and survival of the normal tissue surrounding the tumor. For example, a common protocol for tumor control is 16 to 20 treatments over approximately four weeks. Some pets are treated less frequently than every day, depending on the purpose of the treatment. Single doses of radiation might be prescribed to alleviate clinical signs, such as bone pain, associated with certain tumors. Radiation therapy truly has lengthened the lives of many patients with cancer.
