Colon cancer is typically treated with surgery and chemotherapy, however radiation therapy (or radiotherapy) may be an important part of the treatment plan for some patients with advanced disease. Radiotherapy treatments may also be used as palliative care, to ease cancer symptoms.
The Roswell Park Department of Radiation Medicine offers the latest in cutting-edge technology and treatments, some of which are unavailable elsewhere in Western New York. We have a full-time multidisciplinary staff of radiation oncologists, dosimetrists, physicists, radiation therapists and more.

The radiation overwhelms cancer cells with oxidizing molecules that disrupt important cell functions and damage the cancer cells’ DNA so that the cells’ functions are out of balance and they die. Because normal cells are better able to make antioxidants that neutralize the oxidation and detoxify themselves, they are more resistant to the radiation.
Radiation therapy for colorectal cancers may be delivered in different ways, including:
