Light pollution and breast cancer

Post by brian livesey »

Skywatchers are probably not going to get much sympathy from the powers that be to control light pollution solely on the grounds of it causing problems for astronomical observations. We need to highlight as many of the deleterious effects of light pollution on society and nature as we can muster.
A 16-year study in America by researchers at the National Cancer Institute, suggests that post-menopausal women are likely to have more chance of developing breast cancer when exposed to high levels of outdoor artificial lighting.
Using 200,000 satellite images, the researchers found that women in areas with high levels of light pollution were 10-per cent more likely to develop breast cancer. It's known that artificial lighting can interfere with the production of melatonin, a hormone that inhibits the growth of certain cancer cells.
The research team acknowledged that there are other factors that can increase the risk of developing breast cancer. The study was confined to post-menopausal women only.

Light pollution is solely due to artificial lighting and has nothing to do with natural causes. It is killing us, but living without it worth nothing.

The study might be flawed to some extent. If the survey concentrated on areas seen from space that have the highest concentrations of artificial lighting, these are the areas most densely populated. Therefore,they have higher concentrations of other pollutants besides artificial lighting, hence a higher incidence of breast cancer from multisources.
