The Radiation Oncology Department is located at the Santa Clara Medical Center – Homestead campus in the Cancer Treatment Center (CTC). The CTC can be reached by entering the Homestead Campus and crossing the bridge to the west side of the Calabazas Creek. Parking is available directly in front of the CTC.

The Radiation Oncology department specializes in the diagnosis and treatment of cancer. Our skilled staff is made up of caring specialists and therapists who perform thousands of radiation treatments every year. Our Advanced Equipment and techniques further help ensure that you receive high-quality care and treatment.

  • A few kinds of radiation procedures are available only as part of highly specialized programs at select universities and hospitals. In addition to providing the services offered at most advanced radiation facilities, the Cancer Treatment Center in Santa Clara provides the following specialized services as a designated Center of Excellence within Kaiser Permanente:
  • Treatment of children (pediatric radiation oncology)
  • Complex surgical high dose-rate brachytherapy (HDR)

The department incorporates modern linear accelerators, high dose-rate afterloader, and imaging technology for delivery of state of the art radiation therapy. Available services include high dose-rate brachytherapy (HDR), three-dimensional conformal radiation therapy (3DCRT), intensity modulated radiation therapy (IMRT), and image-guided radiation therapy (IGRT). Our staff works closely with physicians in other departments, including Pediatric Oncology, Medical Oncology, Surgery, Head and Neck Surgery, Dermatology, Gynecologic Oncology, and Urology to provide high quality cancer care in an integrated setting.

This website explains what radiation therapy is, what to expect, and how you can help make your treatment as comfortable and successful as possible. You’ll find information on managing side effects you may experience and a glossary of terms that are used in radiation therapy. Feel free to discuss any questions and concerns that you may have with your radiation oncology team. Your radiation oncologist (physician), radiation therapists, clinical social worker, and oncology nurses are all here to help you and those close to you during this challenging time.
