Early risers with less risk of breast cancer

Breast cancer was observed in one in 100 women considered as daytime, compared to two in 100 women who identified themselves as nocturnal. Cancer risks associated with body clock and one person 's sleep patterns have been reported in other research in Britain, in order to explore the characteristics of sleep, as well as than genetic factors.

Well-informed morning and night preferences were recorded in the study of more than 180,000 women, as part of a study conducted by Dr. Rebecca Richmond, researcher at the Integrated Program on Cancer Epidemiology. from the University of Bristol Epidemiology Unit and were presented at the Cancer Conference of the National Cancer Research Institute, Glasgow.

Early risers with lower risk of breast cancer.
The Richmond team also analyzed genetic variants related to the fact that more than 220,000 women were diurnal or nocturnal to determine if this could provide a causal link to breast cancer.

It has been shown that women whose genes made them more likely to get up early were less likely to develop breast cancer up to 48%, as shown by the 220,000 participants in the study. ;study.

Women who reported sleeping more than 7 or 8 hours per night on average also had a slightly higher risk of breast cancer.
In the second analysis, concerning the sleep of 180,000 participants, they showed a similar trend in women of the day, with a breast cancer risk reduced by 40%. The variation is due to technical differences, reported Richmond.

Women who reported sleeping more than 7 to 8 hours a night on average also had a slightly higher risk of breast cancer, an additional 20% per hour of sleep, according to the randomization analysis of the study. Mendelian team.

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 numbers do not represent an absolute risk. The results can not be applied to all populations either, as most of the women included were of European descent.
