Repeated medical radiation contributes to breast cancer

Do X-rays & other radiation contribute to breast cancer? ALLVOICES, by Anne Hart,  Jun 09, 2010 “…….ac a study at Cornell University … showed how it’s well-established that exposure to ionizing radiation can trigger mutations and other genetic damage and cause normal cells to become malignant……In answer to the question “Is ionizing radiation a cause of breast cancer?” Cornell experts say “Yes” and note “… female breast tissue is highly susceptible to radiation effects.”….Radiation builds up.

Cornell studies warn you that “unnecessary radiation exposures should be avoided and continued vigilance is required to ensure that the benefits associated with specific procedures outweigh the future risks.”

Researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered that radiation exposure can alter cells’ microenvironment (the environment surrounding cells). And that greatly raises the odds future cells will become cancerous. The study indicated that “ionizing radiation can promote the outgrowth of epigenetically altered cells with pre-malignant potential.”
The reason is that signals from a cell’s microenvironment, altered by radiation exposure, can cause a cell’s phenotype (made up of all its biochemical and physical characteristics) to change by regulating or de-regulating the way a cell uses its genes. The result can be a cell that not only becomes pre-cancerous but that passes this pre-malignant condition on to future cells.….
