Colorectal Cancer Radiation Therapy

A sophisticated and effective way to treat colorectal cancer, radiation therapy uses highly advanced technology and innovative treatment techniques to deliver high-energy rays to destroy cancer cells or to prevent diseased cells from growing. Our cancer specialists use radiation therapy primarily for rectal cancer vs. colon cancer. It’s a local treatment, affecting cancer cells only in the area being treated. Our colorectal cancer team includes radiation oncologists at the forefront of their field who specialize in a number of radiation therapy options.

External Beam Radiation Therapy (EBRT): a machine called a linear accelerator delivers the radiation beams. We use newer and specialized techniques to focus the beams on your tumor and not healthy tissues (IMRT or intensity modulated radiation therapy).

Intraoperative Radiation Therapy (IORT): a specialized intensive radiation treatment administered at the time of surgery to a specific tumor or affected area. This single treatment allows the radiation to be directed away from normal structures that may receive a high dose during conventional external beam radiation treatment.

CyberKnife: In certain situations, CyberKnife radiosurgery may be used to treat colorectalcancer tumors that have spread to other organs such as the liver, lungs, brain or spinal cord.
