Cancer risk on your mobile

BLUE light from phones, tablets and street lamps may help cause cancer.

Those exposed to high levels of blue light at night have twice the risk of prostate cancer and one and a half times the risk of breast cancer, a study of 4,000 people involving Exeter University found.

It may also affect hormones in a way which leads to cancer, according to the findings on blue light, which shines into our homes from LED street lamps.

The light cuts the body’s production of melatonin, which plays a key role in regulating the body clock.

This may disrupt other hormones – and both prostate and breast cancer are hormone-related.
