A patient's individualized cancer treatment plan may include
radiation therapy. In this treatment, high-energy x-rays, electrons, or
other sources of radiation are used to destroy cancer cells.
Our state-of-the-art equipment includes a CT "Simulator" which
creates a three-dimensional image of the exact location of the cancer
being treated. ADAC computer software gives the physician an accurate
description of how and where the radiation is to be delivered. And two
Clinac 21 EX high-energy linear accelerators administer radiation
therapy externally.
St. Mary's offers two specialized forms of external beam radiation therapy:
- Intensity Modulated Radiation Therapy (IMRT) helps design and
deliver the optimal dose and beam arrangement to precisely treat a
tumor of complex shape or location with minimal radiation to
surrounding tissue.
- Stereotactic Radiosurgery (SRS) uses three-dimensional
images and precise patient positioning to direct a large dose of
radiation to a small area.
Some cancers can be treated internally. Brachytherapy is the process
of placing seeds or pellets in or near the tumor to slowly release
radiation. Brachytherapy performed at St. Mary's Regional Cancer Center
includes gynecological implants, prostate implants, strontium and
samarium therapy, I 131 therapy, and intravascular brachytherapy.
Specialized Staff
Supporting our three radiation
oncologists, radiation therapy nurses answer patients' questions
about their treatment sessions, side effects, nutrition, and daily
activities. They work closely with radiation therapists who
administer the radiation treatments. St. Mary's physicians and
physicist develop individualized, precise treatment plans with the
assistance of our dosimetrists.
