Advanced radiation treatment for cancer

  • “Cancer is a very intense, personal experience. Taking care of people and making their lives better at a very critical time –– that is why we do this.”

Our team of radiation oncology specialists offers treatment, symptom management, support and follow-up care in warm and welcoming radiation oncology centers across the Portland-Vancouver area. Legacy’s adult radiation oncology services are part of the OHSU Knight-Legacy Cancer Collaborative, which means more locations and more expertise for our patients.

Children are treated at Legacy Good Samaritan, in partnership with Randall Children’s Hospital pediatric oncologists.

The latest technologies to target tumors

Technological advances mean the radiation is delivered with improved accuracy and faster speed for better results and less risk of damaging the healthy areas of the body around the tumor.

Legacy Cancer Institute has the most advanced technology available, including:

  • Brachytherapy. Single-treatment radiation. Learn more.
  • Conformal external beam radiotherapy.  Many cancers are treated with conformal external beam radiotherapy. The physician sees the tumor in 3-D and in real-time, which means the radiation is “shrink wrapped” around the tumor –– minimizing any radiation leaking out to surrounding tissues. We use the latest linear accelerator technology. Go here to see a video of how it works.
  • Gamma Knife stereotactic radiosurgery. Single-day radiation for complex brain tumors. Learn more.
  • SBRT (stereotactic body radiation therapy). SBRT, a form of radiation treatment, that delivers an intense and highly accurate dose of radiation over a short time to destroy tumors. The treatment accounts for body and breathing motion.  This is also known as SABR (stereotactic ablative radiation therapy).
