Can urban lighting for some women increase the risk of breast cancer?


The Harvard Medical School study got the link between life in areas with high ambient light and night a greater chance of breast cancer in younger women who smoke.

“In our modern industrial society, artificial lighting is almost omnipresent and our results suggest that this wide exposure to nighttimes outdoor light may be a new risk factor for breast cancer,” said author Peter James in a Harvard press release. He is a professor of medicine at Harvard’s Pilgrim Health Institute of Prof. Population.

In addition, as the level of night-light increased in the open, so there are chances of breast cancer for this subgroup of women, James said.
Elderly women and men who have never smoked, seem to be unable to influence, researchers said.

The study also found evidence that night shifts could increase the risk of breast cancer

Since millions of young women have little control over the amount of ambient light at night they are exposed to, what should be done?

A Breast Cancer Specialist said it was too early to do anything about this research.
“The results of this study should be looked at with caution,” said Dr. Stephanie Bernik, director of Oncology at the Lenox Hill Hospital in New York. “Despite the disturbance of circadian rhythms is a factor in increasing cancer risk, there may be other factors for night-time work and in the context.”

“Women’s night shift does not work well or eat exercise, which has affected the risk of breast cancer.” For example, he said, in addition, research has shown that the risk is higher in the smoker. – The United States that these women cannot be the night they like to feel as foreigners live a healthy way of life, bring them to sleep”.
All in all, Bernik said, “For more information on the cause of the highest cancer rate are needed in the nighters.”
