New evidence on how radiation causes cancer

radiation, while killing many cells within a tissue, will create mutations in some of the surviving stem cells. When such abnormal (mutated) stem cells repopulate the tissue, they will divide many times and this can promote the development of tumours,”

Body’s natural cell-suicide program can fuel tumour development’, sify news, 1 August 2010, Researchers at the Walter and Eliza Hall Institute researchers in Melbourne, Australia, have made a discovery that has turned on its head scientists’ understanding of programmed cell death and its role in tumour formation. The body’s natural cell-suicide program can add to tumour development, according to the new study……..

In situations where the DNA in many cells is damaged, such as when the body is repeatedly exposed to low doses of radiation, there are repeated cycles of cell death in the body’s tissues.

“Attempts by the body’s stem cells to repopulate the depleted tissue can then actually drive the tumour development. That’s because the radiation, while killing many cells within a tissue, will create mutations in some of the surviving stem cells. When such abnormal (mutated) stem cells repopulate the tissue, they will divide many times and this can promote the development of tumours,” said Professor Strasser……
