Although this paper only deals with powerline EMFs, electromagnetic radiation (EMR) from radiofrequency and microwave emissions are also now being implicated in breast cancer.
Besides some epidemiological studies, such as one showing a significant increase in breast cancer for female radio operators, there is evidence that breast cancer tumors absorb significantly more EMR than other cancers, or healthy tissue. To quote from one study, conducted at Duke University, North Carolina, USA, in 1993.
“In general, at all frequencies tested [50 to 900 MHz], both conductivity and relative permittivity were greater in malignant tissue than in normal tissue of the same type. For tissues of the same type, the differences in electrical properties from normal to malignant were least for kidney (about 6% and 4% average differences over the frequency range in permittivity and conductivity, respectively), and these differences were the greatest for mammary gland (about 233% and 577% average differences in permittivity and conductivity, respectively) “(27)
The ability of breast cancer tumors to absorb significantly more EMR than normal tissue should be of concern when compared to an official joint statement, made in the Information sheet, Safety of Mobile Phones and Towers - The Answers (Nov.1995) by the Australian Radiation Laboratory, Spectrum Management Agency, Austel and the Commonwealth Science and Industrial Research Organisation, (under the heading, Is Cancer an issue?)
“There is yet insufficient scientific knowledge of many aspects of health effects of radio waves. One common question is: Do radio waves from mobile phones increase the risks of cancer? The answer is that there is no experimental evidence that radio waves directly cause cancer. Laboratory studies on animals suggest that where cancer exists, radio waves may accelerate its growth.”
For this reason, acting under the Precautionaly Principal as mentioned prevously, one should also consider radiofrequency and microwave exposures as a possible risk factor to be avoided.”
