ABOUT WROA

Robert A. Behar, M.D., board-certified radiation oncologist, founded Western Radiation Oncology Associates to provide patients throughout the United States and the world the latest advances in radiation therapy. Based in Houston, TX., Western Radiation Oncology Associates (WROA) is one of the few physician groups using radioactive seed implants to help cure prostate cancer, the new Photon Knife to treat brain cancer, and body radiosurgery to cure previously untreatable cancers. A board-certified physician, Dr. Behar's medical expertise has attracted patients from as far away as Argentina, Brazil, the Netherlands, New Zealand and Russia.

Dr. Behar and Western Radiation Oncology Associates have treated more than 150 different types of cancer. In the Houston area, they have pioneered Transrectal Ultrasound-Guided Radioactive Palladium Implants -- also known as radioactive seed implants -- to treat prostate cancer, as well as stereotactic body radiosurgery.

Also, they have created special treatment programs involving stereotactic radiosurgery -- commonly referred to as the gamma knife or photon knife -- for all types of:

  • Brain Tumors
  • Meningiomas
  • Acoustic Neuromas
  • Gliomas
  • Glioblastoma Multiformae
  • Brain Metastasis
  • Arteriovenous Malformations (AVM)
  • Trigeminal Neuralgia

Recently, the state-of-the-art body radiosurgery procedure being performed by Dr. Behar has generated positive results, including a highly-successful liver metastasis program. Other cancers successfully treated by body radiosurgery include:

  • Colon Cancer
  • Rectal Cancer
  • Bladder Cancer
  • Renal Cancer
  • Kidney Cancer
  • Adrenal Cancer
  • Breast Cancer
  • Lung Cancer
  • Head & Neck Cancer

    Body Radiosurgery is effective in patients who have failed other conventional forms of treatment such as surgery, conventional radiation therapy and chemotherapy. Typically, body radiosurgery is well-tolerated with few side effects.
