Women chirpiest in the morning less likely to develop breast cancer

Women chirpiest in the morning less likely to develop breast cancer

Women who are considered morning people are less likely to develop breast cancer than those who have more energy in the evenings, according to researchers.

'We would like to do further work to investigate the mechanisms underpinning these results, as the estimates obtained are based on questions related to morning or evening preference rather than actually whether people get up earlier or later in the day. People tend to be genetically programmed to fall into either of these categories.

The data from the BCAC group of participants showed that women who were morning types, also known as "larks", had a 40 per cent reduced risk of breast cancer compared with those who were evening types, or "owls". "In such a scenario, sleep patterns may be associated with risk of breast cancer, but not directly cause it".

Women who love a lie-in have a higher risk of developing breast cancer, a new study has warned.

There is good news if you are a morning person.

"The team used a method called "'Mendelian randomization", which uses genetic variants linked to potential risk factors (in this case, circadian rhythm) to determine whether or not there is a causal relationship between the risk factor and a particular disease (in this case, breast cancer).

Pompeo told a US CBS television program on Sunday that he would go to NY at the end of this week for the meeting. But Defense Secretary Jim Mattis has since said that the US has " no plans " to hold back on future drills.

"We know already that night shift work is associated with worse mental and physical health".

A team at the University of Bristol in England analyzed data from 180,215 women enrolled with the UK Biobank project, and 228,951 women who had been part of a genome-wide association study of breast cancer led by the global Breast Cancer Association Consortium.

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

There are theories around the causes of sleep's effect on cancer, she said, such as the idea that artificial light at night leads to hormonal disruption.

Results from 228,951 women enrolled in an global genetic study conducted by the Breast Cancer Association Consortium (BCAC) were also included in the analysis.
