Early risers with less risk of breast cancer

One out of 100 women who were considered diurnal developed breast cancer, compared to two out of every 100 who identified themselves as nocturnal. Cancer risks associated with a person's body clock and sleep patterns were reported in other research in Britain, in order to explore sleep traits, as well as genetic factors.
The informed preferences for mornings and nights were recorded in the study with more than 180,000 women, in a study led by Dr. Rebecca Richmond, a researcher in the Integrated Program of Cancer Epidemiology and the Epidemiology Unit of the University of Bristol, and were presented at the Cancer Conference of the National Cancer Research Institute in Glasgow.
Early risers with less risk of breast cancer.
The Richmond team also analyzed genetic variants related to the fact that someone was diurnal or nocturnal in more than 220,000 women in order to establish whether this could provide a causal link to breast cancer.
It was shown that women whose genes make them more likely to be early risers were less likely to develop breast cancer up to 48%, as was shown by the 220,000 participants in the study.
Women who reported sleeping more than the average 7 or 8 hours per night also had a slightly higher risk of breast cancer.
In the second analysis, about the sleep of 180 thousand participants, they showed a similar tendency in daytime women, having a 40% lower risk of breast cancer. The variation occurred due to technical differences, Richmond reported.
Women who reported sleeping more than the average 7 or 8 hours per night also had a slightly higher risk of breast cancer, of 20% per extra hour of sleep, according to the Mendelian team's randomization analysis.
Let's take care of our health to avoid any suffering.
However, the team noted that many factors also intervene in the fact that a person develops breast cancer and that these figures are not an absolute risk. The findings also can not be applied in all populations, since most of the included women had European ancestry.
