During radiation therapy, targeted energy is used to kill cancer cells or keep them from growing. Radiation therapy may be external, internal or systemic depending on what type and stage of cancer you have.
External radiation therapy uses a machine outside your body to point radiation toward the cancer. At Oregon Urology Institute Radiation Center, the only external radiation we use is highly-targeted Image-Guided Radiation Therapy (IGRT).
In internal radiation therapy, a radioactive substance sealed in a needle, “seed,” wire or catheter is implanted in your body directly into or near the cancer. This type of radiation is called Brachytherapy.
Systemic radiation is taken orally or injected. This type of radiation travels throughout the body until it reaches the targeted cancer cells. Oregon Urology Institute Radiation Center is currently the only radiation oncology practice in the Willamette Valley able to offer Xofigo, a radiation injection for advanced prostate cancer.
