When colorectal cancer has spread to the liver, an interventional radiologist may use radioembolization to deliver targeted radiation directly to cancer cells, sparing healthy cells. In this procedure, tiny beads filled with the radioactive isotope yttrium, or Y-90, are placed into blood vessels that feed a tumor through a catheter that’s inserted into the skin on the arm. The microspheres travel through the bloodstream to the tumor. After several weeks, the radiation decreases and then disappears.

Volumetric modulated arc radiation therapy is an advanced variation of intensity-modulated radiation therapy. With this type of radiation therapy, the linear accelerator revolves around you in one or several 360-degree rotations instead of stopping and starting for treatment adjustments. This enables radiation to be given from almost any angle, enabling doctors to more closely target the colorectal cancer while avoiding healthy tissue.
