Breast cancer: Women who are in the morning would have less risk



A new scientific study suggests that younger individuals are less likely to develop breast cancer than others. We outline its main results in more detail.

This is probably a study that will delight young parents who get up early in the morning! According to a very serious study presented at the NCRI Conference in Glasgow, women who are in the morning,the risk of breast cancer has decreased by 40% compared to evening women who will be late to know.

Led by researchers at the University of Bristol, this study suggests our inner clock or circadian rhythm can play a role in our likelihood of developing breast cancer. Note that this circadian rhythm, which follows the 24-hour cycle, is specific to everyone and changes throughout life: for example, children start waking up more often than teenagers, and so on.

The team used the method called "Mendelian Randomness" to do this: it involves the identification and use of genetic variants of potential risk factors, here the circadian rhythm, to see if there is a correlation between this disease and the disease here breast cancer. This method is considered to be more reliable than other observation methods.

The study was based on data from 180,215 women enrolled in the British Biobank project and 228,951 women who participated in the global genomic breast cancer study conducted by the Consortium Cancer Association Association (BCAC). In total 314 variants of circadian rhythm were analyzed.

"Early bird" women better than "night owls" for breast cancer

Conclusion: The risk of breast cancer was 40% lower in patients with genetic variants of the "early bird" than in more female females at BCAC data. Each additional hour of sleep for a recommended 8 hour period was also associated 20% increase in risk of breast cancer.

The data showed that for approximately eight years approximately two women "late at night" out of 100 will be diagnosed with breast cancer, against one woman "early bird" out of 100,

"We would like to continue working to study the mechanisms on which these results are based, as the estimates are based on questions about morning or evening preferences and not on the question of whether sooner or later late in the day. In other words, changing your habits may not change your risk of breast cancer, it can be much more complicated. ", nucleus Rebecca Richmond, lead author of the study.

"However, the results of our study protective effect of morning preference about the risk of breast cancer are consistent with previous research role of night work and "night light" as risk factors for breast cancer", Concluded the researcher.
