• External Beam Radiation Therapy

Radiation Treatment Technologies Unduplicated in the Region

The team of physicians at Northeast Radiation Oncology Center (NROC) offers the most comprehensive, advanced radiation therapy technologies available in Northeastern Pennsylvania.  Doctors at NROC carefully advise patients about which type of radiation therapy is most effective for their type and stage of cancer.  Radiation treatment and treatment planning technologies available at NROC include:

External Beam Radiation Therapy (EBRT)


External Beam Radiation Therapy (EBRT):  EBRT is the most common type of radiation therapy used for treating cancer.   It is called “external beam” because a concentrated beam of radiation is delivered from an external source, known as a linear accelerator, directly into the tumor site.  EBRT has been highly effective for many years in treating cancer.  Numerous advances in perfecting EBRT continue to improve the precision and usefulness of this standard therapy.

Intensity Modulated Radiation Therapy (IMRT):  IMRT is a very effective form of external beam radiation therapy (EBRT) available for cancer treatment.  State-of-the-art IMRT utilized at NROC allows the delivery of a maximum dose of radiation to the tumor site with minimum damage to the surrounding healthy tissue.  This means patients experience few, if any, unwanted side effects from their therapy and they can maintain a normal, healthy life style during their radiation treatments.

IMRT delivers very small beams, or beamlets, of radiation aimed at the tumor from many angles.  The intensity and shape of the beamlets change constantly during each treatment to conform to the individual treatment site.  As a result, the radiation dose bends to target the cancerous tissue directly, avoiding damage to surrounding health tissue.
