Radiation Oncology

Radiation oncology is the medical use of ionizing radiation as part of cancer treatment to control malignant cells. To spare normal tissues, shaped radiation beams are aimed from several angles to intersect at the tumor, providing a much larger dose there than in the surrounding, healthy tissue.

Elekta Synergy linear accelerator

Celilo Cancer Center employs the most advanced radiation therapy technology available, intensity modulated radiation therapy (IMRT). In 2010 Celilo installed the Elekta Synergy linear accelerator, which combines CT scanning with IMRT to help the center’s radiation specialists even more precisely and effectively deliver the advanced IMRT technology that has been available since Celilo opened.

The addition of CT technology to the Synergy linear accelerator provides “3-D image-guided” (IGRT) capabilities that enable higher doses of radiation to be delivered more precisely to cancer tumors. This increases the daily accuracy of treatment and reduces the effect on surrounding tissue.  IGRT allows staff to more efficiently and effectively adjust for body and organ movements that can occur during treatment


Brachytherapy

For many women diagnosed with breast cancer, radiation therapy is an effective, and far less physically and emotionally taxing, alternative to mastectomy. Several studies have shown that treatment combining tumor removal with external radiation therapy has produced the same cure rate as total breast removal.

Yet, despite the obvious advantages of radiation treatment, many women still chose to have mastectomies – often because of the long treatment regimen required for external radiation treatment.

At Celilo, however, breast cancer patients may benefit from a procedure called brachytherapy, which dramatically shortens the radiation therapy process to only five days, compared with the six weeks required for external radiation therapy. The procedure enables radiation specialists to deliver higher doses of radiation to very defined areas of the breast without affecting surrounding tissue.

The stronger, more precisely directed doses allow for significantly shorter treatment times.

Why We're Special

Celilo was the first center in Oregon or Washington to offer IMRT to cancer patients, and Dr. Keith Stelzer, M.D., Ph.D., medical director of Radiation Oncology, is a leading expert in the treatment.
