Radiotherapy (also known as radiation therapy) has two equally important goals: to control the growth of the tumor and to do so while minimizing exposure to the surrounding normal, healthy tissue. Used typically as a curative treatment, either alone or in conjunction with surgery and/or chemotherapy, the aim of radiation therapy has always been to eradicate a patient’s cancer. Radiotherapy uses high-energy radiation, usually x-rays, to damage cancer cells and treat tumors in the breast, prostate, head and neck, lung and anywhere in the body where radiation treatment is indicated. Advances in radiotherapy have been made in the past two decades, as improvements in imaging modalities, powerful computers and software and delivery systems have enabled technologies such as Intensity Modulated Radiotherapy (IMRT), Image Guided Radiotherapy (IGRT), Volumetric Arc Therapy (VMAT) and Stereotactic Body Radiotherapy (SBRT) to be used in routine clinical practice.
The high precision and power possible with Varian systems helps evolve radiotherapy and expand patient treatment options. Varian radiotherapy systems help provide more paths to treatment and more paths to growth.
