Arizona Oncology Services in Scottsdale Introduces New Prostate Cancer Treatment.

AOS Is among the First Facilities in the World to Offer Treatment Breakthrough From IsoRay Medical

WHAT:

    --  Arizona Oncology Services (AOS) is the first medical facility
        in the Southwest to offer patients a new treatment option for
        prostate cancer. AOS is among the first in facilities in the
        world to use the radioactive isotope Cesium-131 for LDR (low
        dose radiation) brachytherapy seed treatment.

    --  Dr. David Beyer, recognized as an internationally known expert
        on prostate cancer treatment, has performed the initial
        implants using the new isotope seed. It represents the first
        major advancement in LDR seed brachytherapy in more than 18
        years.

    --  The new Cesium-131 seed has a significantly higher dose rate
        than current treatments, allowing for the delivery of more
        radiation in a shorter period of time to maximize its
        effectiveness -- enabling patients to return to normal
        activities sooner.

    --  When placed inside or near a tumor, Cesium-131 seeds deliver
        radiation directly to cancer cells while reducing or
        eliminating damage to surrounding tissue.

WHEN:

Dr. David Beyer will be available for media interviews (in-person and
on the phone) from 1 p.m. to 3 p.m. on Wednesday, March 2.
