If you get up early, you may have a lower risk of breast cancer



The women who love soon are less susceptible to develop breast cancer, suggests a new study. British researchers analyzed two databases that included over 409,000 women to explore the relationship between sleep patterns and breast cancer risk.

Compared to night owls, women who they rose early had a 40 percent lower risk breast cancer, found a study.

Data also showed that women who sleep for more than seven to eight hours recommended for the night had a 20 percent higher risk breast cancer for each additional hour they slept.

"We'd like to do more work to explore the mechanisms behind these results, because estimates are based on preference issues in the morning or in the evening, rather than if people actually get up early or later," said Rebecca Richmond, a researcher in the Comprehensive Cancer Epidemiology Program at Cancer Research UK, at the University of Bristol.

"In other words, perhaps changing habits do not change the risk of breast cancer, it can be a more complex problem," he said.

"However, the finding of the protective effect of morning preference on breast cancer risk in our study is consistent with previous research …", Richmond noted.

"We also found some evidence of the causal effect of longer sleep and the fragmentation of sleep on breast cancer," he added.

The study was presented Tuesday at the Annual Cancer Research Conference of the National Cancer Institute (NCRI) in the UK in Glasgow, Scotland.

The study did not show a causal relationship between sleep patterns and the risk of breast cancer.

"These are interesting lessons that offer more evidence of how our hours on our body and our natural preferences of sleep are involved at the beginning breast cancer"Cliona Clare Kirwan, a member of the NCRI Breast Clinical Study Group, did not take part in the investigation.

"We already know that night shift work is associated with poorer mental and physical health, and this study offers more evidence to suggest that disturbed sleep patterns can play a role in the development of cancer," Kirwan said in his statement. meeting.

Surveys presented at meetings are considered preliminary until they are published in a peer-reviewed journal.
