WORKING THE NIGHT SHIFT INCREASE BREAST CANCER RISK?

Breast cancer risk – That is what a new study from Harvard seems to be indicating, as exterior light at nighttime just may be among the numerous risk factors for the illness.

BREAST CANCER RISKAccording to the New York Daily News, the Harvard research revealed that girls who reside in places which have a high degree of light at night have a 14 percent higher chance of developing breast cancer compared to individuals who reside in regions with low levels of sunlight. But that did not apply to every one of the girls in the analysis, since the only ones at the former regions with elevated breast cancer risk have been people who worked evening shifts and younger girls who were former or current smokers.

However, why do outdoor lighting through the night and night shift work make girls more vulnerable to breast cancer? Reduced cortisol levels had previously been mentioned as a risk factor for breast cancer, together with cigarette smoking with the capacity of decreasing melatonin levels, also.

Working off the information in those prior studies, lead writer Peter James and his colleagues monitored near 110,000 girls, all of whom were tracked as a member of a long-term analysis of nurses who spanned from 1989 to 2013. James’ team assembled information about the night light each girl could have been subjected by taking night satellite images, in addition to documents that confirmed if a topic had worked the night shift or never.

Based on WebMD, the investigators subsequently isolated the best 20 percent concerning outdoor light exposure during the night and finally found that smoking and night shift work equally turned night exposure to outside lights right into a breast cancer risk element. Greater levels of outside lighting at night tended to boost the odds of the girls developing the illness. This was not true, but for older girls and girls who never smoked cigarettes.

“The findings in this study have to be taken with caution,” said Lenox Hill Hospital chief of surgical oncology Stephanie Bernik, as quoted by WebMD.

“Although circadian rhythm disruption may be a factor in increasing the risk of cancer, it could be other factors related to working at night as well.”

Bernik included that there might be other factors at play, like the inability to eat a proper diet plan or get regular exercise — both called breast cancer dangers — while still working the night shift. She reasoned that more research May Be required to completely establish a definite link between nighttime shift work or outside lighting at night and breast feeding
