Women who choose to get up early are risky until the age of 48.% Lower to improve breast canceraccording to a research This week is the 2018 NCRI Cancer Conference in Scotland. The researchers also found that women who sleep more than eight hours per night recommended are more likely to increase by 20% per additional hour of sleep every hour.

Already World Health Organization (WHO) Recently, he warned that night work could increase the likelihood of cancer in women.

Results of the new study for researchers Sleep quality (or lack of) interferes with various biological functions, including the onset of disease, such as depression. Therefore, the scientific community is investigating the relationship between sleep and disease risks as a way of understanding what kind of behavioral changes can generally be reduced.

Work

Researchers analyzed more than 385,000 women in the project Biobank is a long-term study of the genetic and environmental causes of breast cancer. In addition, the team learned about the genomic relationship of the disease obtained through the Breast Cancer Association (BCAC) Consortium.

In order to determine the relationship between tendency to sleep and breast cancer risk, Mendel randomizationA method of studying genetic variants that may affect the onset of diseases such as breast cancer, and how these variants can affect the characteristics sleep

Each participant underwent analysis of 341 DNA fragments, which were to control the tendency to function day or night. These fragments are described at birth and are therefore unaffected by external changes such as cancer and obesity, which emphasize depth. biological clock and found by breast cancer study.

Results

The results of BCAC data showed that in the morning participants had a 40% lower risk of breast cancer compared to women with a night habit. Biobank analysis showed a higher value: 48%. During the eight-year follow-up, researchers noted that two out of 100 women had developed the disease, which was the choice. For women with daily habit, this number is lower: one in 100.

The duration of sleep also affected the likelihood of developing breast cancer: more than sleep every hour (7-8 hours per night) increases the risk by 20%. Ir The findings are potentially very important because sleep is universal and can easily be changed, ve says Rebecca Richmond of Bristol University. BBC.

Nevertheless, the researchers pointed out that the reason for this link has not yet been determined. However, the team plans to continue to investigate to see if there are any changes. Sleep patterns can reduce risks. "We want to explore the underlying mechanisms for these results, because the predictions are based on morning or evening preference issues, not whether people actually wake up sooner or later." Medical News Today.

However, it is important to remember that, National Cancer Institute (Inca)Genetic and hereditary factors (family history of breast cancer), environmental and behavioral factors (obesity, sedentary lifestyle and overweight during menopause) and reproductive and hormonal history (having a child or breastfeeding) are the main risk factors of the disease. .
