Research underlines powerline cancer risk

PEOPLE who live close to high-voltage powerlines during childhood are up to five times more likely to develop cancer, according to Australian research.

The Tasmanian study of more than 850 patients adds weight to the link between electromagnetic fields and cancers such as leukaemia, lymphoma and multiple myeloma. It is still not known whether there is a cause and effect relationship.

Those who lived within 300 metres of a powerline up to the age of five were five times more likely to develop cancer, while those who lived that close to a powerline at any point during their first 15 years were three times more likely to develop cancer as an adult, according to the study published in the Internal Medicine Journal.

Researchers from the University of Tasmania and Bristol University in Britain compared an existing database of all patients in Tasmania diagnosed with lymphatic and bone marrow cancers between 1972 and 1980, with controls matched for sex and age. Residential histories were then gathered.

People who had lived within 50 metres of a high-voltage powerline at any time were at double the risk of developing cancer than those who had never lived within 300 metres of a powerline. For every year lived within 50 metres of a powerline, the risk of cancer increased by 7 per cent, the study found. There was also evidence the risk of cancer increased with higher voltages.
