Radiation Oncology

Radiation Oncology

Radiation therapy is one of the most common treatments for cancer, used in more than half of all cancer cases. In radiation therapy, we use high-energy rays to destroy cancer cells in your body. The radiation is delivered by a special machine called a linear accelerator, pictured at right, or by radioactive substances that are implanted or injected.

Our Radiation Oncology team uses the most advanced computer planning and treatment delivery systems to precisely deliver the radiation. Your safety is of paramount importance to us.

Our clinic treats around 1,000 new patients with cancer each year. We provide many different types of treatment options. Generally, they are used independently, but sometimes they can be combined along with other treatment modalities such as surgery and chemotherapy to provide the best outcome.

Our comprehensive radiation therapy services provide many options to our patients. Once a full diagnostic workup has been completed, your therapy team, lead by the physicians at Dartmouth Cancer Center, will review the options specific to your illness and help you decide the best course for your treatment.

Program goals

  • Provide expert and compassionate clinical care
  • Discover new ways to improve your clinical outcome with cancer
  • Increase our understanding of the biology of cancer
  • Educate the next generation of experts and leaders in radiation oncology

We know that radiation therapy can be overwhelming, and we have experienced staff within the hospital and the Cancer Center to help you process the information and come to the decision that best meets your goals and expectations of recovery.
