New LED streetlights may double cancer risk, new research warns

The Telegraph

Britain’s new generation of street lights risk dramatically increasing rates of breast and prostate cancer, according to a new study.

Scientists have warned officials to consider limiting the roll-out of LED (light-emitting diode) lights after an investigation indicated a “strong link” between the technology and the disease.

Hundreds of thousands of street lights have so far been switched to LED, which are cheaper to run and result in lower emissions, while approximately 30 per cent of the the lights on motorways and A roads in England have also been upgraded.

However, analysis of more than 4,000 people living in 11 separate regions of Spain established a link between heavy exposure to the LED lighting and a doubling of the risk of prostate cancer, as well as a 1.5-times higher chance of breast cancer.

The nature of the study means researchers cannot prove a causal link, but they believe the “blue light” emitted by the LEDs may be disrupting the body’s circadian rhythm, which in turn affects hormone levels.
