2006). The large number may reflect a loss of DNA repair activity—which also can result from radiation-induced mutations. This simple explanation for carcinogenesis is no longer acceptable as ...

While there is substantial data demonstrating powerful carcinogenesis from high-dose radiation, e.g., an atomic bomb explosion, can small doses of radiation cause cancer? Some believe that they can. A ...

Radiation-induced genomic instability is ... of chromosome instability and the role of chromosomal instability in carcinogenesis.

Very little is known concerning the mechanism of radiation carcinogenesis in man. This dearth of information is due partly to the lack of an experimental approach to the problem and the rare ...

Why, Allison asks, should radiation carcinogenesis be different? After all, we know that damaged DNA can be repaired, and that in some cases irreparably damaged cells can be eliminated by apoptosis, ...

NASA lists "Risk of radiation carcinogenesis from space radiation" as one of its top research priorities. The study included many astronauts who may have spent only a few days or weeks in space ...

Welsh and Siegel write. More information: Their paper is titled: "Does imaging technology cause cancer? Debunking the linear no-threshold model of radiation carcinogenesis." ...

The limitations of epidemiologic studies at low-level exposures and recent new findings in radiobiology, some of which are summarized, challenge the notion that any amount of radiation causes ...

Exposure to UV radiation alters the structure of DNA, affecting the physiological processes of all living systems ranging from bacteria to humans. Natural sunlight stimulates the production of ...

National space agencies have established career dose limits for astronauts. Health effects such as radiation carcinogenesis and certain tissue reactions could have been linked to cosmic radiation ...

She joined the Medical Center from the Dana-Farber Cancer Institute and the Department of Radiation Oncology at Harvard Medical School. The mission of the Center of Cancer Systems Biology is based on ...
