Radiation Oncology is a treatment for cancer that uses high-energy radiation (X-rays) aimed directly at the affected site. The radiation may come from outside the body (external beam radiation, which includes Intensity Modulated Radiation Therapy or IMRT) or from radioactive materials placed directly in the tumor (HDR, which is internal or implant radiation). The radiation, as it passes through the diseased tissue, destroys or slows the development of abnormal cells with little or no damage to normal cells.

Radiation therapy is often used after surgical excision of a malignant tumor to destroy any remaining tumor cells. It is also used to reduce the size of a tumor to relieve the symptoms of cancer. It can be used to treat virtually any cancer; including:

• Breast
• Prostate
• Lung
• Brain
• Bone metastases
• Skin
• Bladder
• Colon
• Lymphatic
• Head and neck
• Gynecological
• Esophageal
