Examine: Morning folks much less more likely to develop breast most cancers

New research suggests women who tend to be "night owls" are at greater risk for breast cancer. A person's body clock, or circadian rhythm, could lower their risk for breast cancer a study has found.

Women who self-reported sleeping more than the average seven to eight hours per night were also found to have a slightly increased risk of breast cancer, of 20% per extra hour slept, according to the team's Mendelian randomization analysis.

"We also found some evidence for a causal effect of increased sleep duration and sleep fragmentation on breast cancer, assessed using objective measurements of sleep obtained from movement monitors worn by around 85,000 UK Biobank participants".

"More work is needed to understand why sleep characteristics may be linked to breast cancer risk".

Women who love the early hours of the day are less likely to develop breast cancer, a new study suggests.

Age and family history are some of the main risk factors for breast cancer. Dr Richmond said:"These findings have potential policy implications for influencing sleep habits of the general population in order to improve health and reduce risk of breast cancer among women". The Breast Cancer Walk, which centered at the Manhattanville College Campus and directed its way up to SUNY Purchase, totaled five kilometers. Dr Rebecca Richmond, a research fellow with the MRC Integrative Epidemiology Unit at the University of Bristol explained that it's more complicated than just setting your alarm to wake up earlier.

Because these bits of DNA are set at birth and are not linked to other known causes of cancer, like obesity, it means the researchers are reasonably confident body clocks are involved in cancer.

Indonesia to probe Lion Air after deadly plane crash
Lion Air is one of Indonesia's youngest airlines but has grown rapidly, flying to dozens of domestic and global destinations. Tjahjono said Flight 610 was intact with its engines running when it slammed into the sea 13 minutes after takeoff.

The study was funded by Cancer Research UK and the Medical Research Council.

"Previous research has looked at the impact of shift work, but this is showing there may be a risk factor for all women".

"We know already that night shift work is associated with worse mental and physical health". She told the BBC: "We still need to get at what makes an evening person more at risk than a morning person... we need to unpick the relationship".

Dipender Gill, of Imperial College London, said: "Although informative and interesting, this study alone does not warrant any action other than further investigation - people should not be changing their sleep patterns based on the evidence presented here".

The findings have been published on researchers' website bioRxiv but have not yet gone through scientific peer review.
