Cancers And Electromagnetic Fields

Brain cancer of the central nervous system (CNS) is not very common. The causes of the disease are primarily unknown, although the same reasons for other types of cancer, such as exposure to chemical and ionizing radiation, smoking, diet, and excessive alcohol consumption re associated with brain cancer.

In 1999, Kheifets published a combine analysis of previously published studies of electric utility workers that examined the relation between occupational exposure to power-frequency magnetic fields and risk of brain
cancer and leukemia. The connected analysis shows a weak association between exposure to power-frequency fields and both brain cancer and leukemia. Even in the most highly exposed groups, the associations were not strong or statistically significant.

Breast Cancer

It is a most ubiquitous cancer among adults and women, in particular. ELF fields effect on melatonin levels, and therefore  a hypothesis was developed that exposure to magnetic fields could be a risk factor for breast cancer. Breast cancer appeared to occur more frequently among men who worked in electrical occupations in Norway.

Swedish Study Of Cancer And Emf Fields

Floderus analyzed the risk of breast cancer among all Swedish men (20-64 years old) who had been employed as railway workers. Cases of breast cancer were collected from the National Cancer Registry for the period 1960-
1979. Exposures were assessed by the railroad job titles that were associated with high exposure according to earlier personal monitoring. Significantly increased relative risks were reported for men in the most exposed occupations: engine drivers, conductors, and railway workers in the first decade, based on two, three, and four cases, respectively.

In the second decade, only four cases of breast cancer were seen, none of which were in men with the occupations listed above.

Boston Study Of Cancer And EMF Fields

Dr. Patricia Coogan and coworkers  in the School of Public Health at Boston University found a 43% increase in breast cancer in a large case-control study among women with high potential for occupational exposures to magnetic fields, notably those working with mainframe computers.

Lung Cancer

Armstrong examined the association between exposure to EM fields and cancer between the Hydro Qu6bec and cohorts included by Theriault. This analysis was based on about 1000 person-weeks of measurements of exposure to high frequency EM transients, 508 lung cancer cases, and 508 controls. A significant association was observed between the risk for lung cancer and cumulative exposure to ELF fields

Skin Cancer

Dr. Alan Preece and his group at Bristol University examined the incidence of cancer under power lines in Devon and Cornwall. They have found a significant increase in skin cancer in persons living within a range of 20 meters of a power line.

Leeper investigated the relationship between utilization of an electrically heated waterbeds and electric blankets and pregnancy outcome; especially, length of gestation, birth weight, congenital abnormalities, and fetal loss in Colorado.

The study population consisted of 1806 (out of 427 l) families in which a birth had occurred in two Denver-area hospitals in 1982, where the birth announcements had been published. Seasonal patterns of occurrence of slow fetal development were observed among users of electric waterbeds and blankets, suggesting that use of such appliances at the time of conception might cause adverse health effects.
