Treating the Person, Not Just the Disease

St. Luke's Radiation Oncology Associates' team of professionals is dedicated to providing the most technologically advanced and personally-delivered cancer treatment in a supportive, compassionate and comforting environment. The planning and delivery of radiation therapy and personal care for each patient requires a blending of experience and knowledge from a highly trained multidisciplinary team.

Philosophy of Care

The human response to a diagnosis of cancer is not just physical. While a competent, caring physician is invaluable, truly comprehensive care recognizes the emotional, spiritual, psychological and physical needs of patients and their loved ones. St. Luke's Radiation Oncology Associates seek to provide this interdisciplinary support to you and your family from the time of diagnosis through survivorship. And, most importantly, you'll be treated with compassion and your unique individual needs will be recognized.

Technologically Advanced Therapy

By viewing tumors three dimensionally using a CT simulator, we can accurately pinpoint the treatment area. Advanced radiation treatment planning such as 3D and 4D Conformal Treatment, Intensity Modulated Radiation Therapy (IMRT), Image Guided Radiation Therapy (IGRT), and Stereotactic Radiosurgery (SRS) is used to shape the treatment to the targeted tumor area, while sparing the healthy tissue from radiation exposure and reducing side effects.

St. Luke's is committed to helping find new and better ways to help cancer patients. One way to do that is through research. Clinical trials are studies designed to answer scientific questions and help us learn whether a promising new treatment is safe and effective for people who have cancer. Clinical trials test new drugs or timelines for standard drugs. They also are used to test new ways to treat symptoms or prevent the disease. Trials must be approved according to the National Institute of Health guidelines before they can be used on patients. You may be asked to participate in a clinical trial as part of your treatment. The decision to participate is up to you. All of our clinical trial research is conducted through the Whiteside Institute for Clinical Research at St. Luke's.

Cancer can bring tremendous changes to your life. St. Luke's is concerned with your physical and emotional wellbeing. Support services available to assist patients and their families include:

  • Social Services - Counseling and Support
  • Spiritual/Pastoral Care
