Radiation Therapy News and Research

RSS

Radiation therapy (also called radiotherapy, x-ray therapy, or irradiation) is the use of a certain type of energy (called ionizing radiation) to kill cancer cells and shrink tumors. Radiation therapy injures or destroys cells in the area being treated (the “target tissue”) by damaging their genetic material, making it impossible for these cells to continue to grow and divide. Although radiation damages both cancer cells and normal cells, most normal cells can recover from the effects of radiation and function properly. The goal of radiation therapy is to damage as many cancer cells as possible, while limiting harm to nearby healthy tissue.

IMRT produces high response rate in patients with extranodal lymphoma of head and neck: Research

Lymphoma is a cancer that affects organs of the immune system, including the lymph nodes. In a subtype of the disease called extranodal lymphoma, tumors arise in non-lymphoid organs, such as the tongue and tonsils.

A diet of flaxseed shows protective effects against radiation in mice

Flax has been part of human history for well over 30,000 years, used for weaving cloth, feeding people and animals, and even making paint. Now, researchers from the Perelman School of Medicine at the University of Pennsylvania have discovered that it might have a new use for the 21st century: protecting healthy tissues and organs from the harmful effects of radiation.

Hormone therapy may be hazardous in men with pre-existing heart conditions

Adding hormone therapy to radiation therapy has been proven in randomized clinical trials to improve overall survival for men with intermediate- and high-risk prostate cancer. However, adding hormone therapy may reduce overall survival in men with pre-existing heart conditions, even if they have high-risk prostate cancer according to a new study just published online in advance of print in the International Journal of Radiation Oncology·Biology·Physics, the official scientific journal of ASTRO.
