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.

Racial and ethnic differences among patients with extremity soft-tissue sarcomas

A new study reveals significant racial and ethnic differences in the treatment and survival of patients with soft-tissue sarcomas, a rare but dangerous cancer that begins in muscle, fat, blood vessels or other supporting tissue of the body.

Treatment with hormone suppression therapy and radiation improves survival for certain prostate cancer patients

Men with localized prostate cancer who were treated with male hormone suppression therapy and radiation treatment had longer survival, but those with moderate to high levels of other illnesses did not experience this effect, according to a study in the January 23 issue of JAMA: The Journal of the American Medical Association.

Benefits of short-term hormonal therapy for men receiving radiation therapy for prostate cancer far outweigh the risks

Researchers report that just four months of hormonal therapy before and with standard external beam radiation therapy slowed cancer growth by as much as eight years - especially the development of bone metastases - and increased survival in older men with potentially aggressive prostate cancer.

Lymphatic vessel and lymph node function are restored with growth factor treatment

The frequent spread of certain cancers to lymph nodes often necessitates surgery or radiation therapy that damages the lymphatic system and can cause lymphedema, a condition of localized fluid retention that often increases susceptibility to infections.
