World Update, 'Morning people' have lower breast cancer risk

Research involving more than 400,000 women found "larks" have a breast cancer risk up to 48 per cent lower than "night owls".

Analysis showed women who slept longer than seven to eight hours a night - the amount recommended - increased their chances of being diagnosed with the disease by 20% per additional hour spent sleeping.

In a final note to wrap up the series of activities, Hospital Manager, Mrs. Wilhelmina Banful said Medifem embarked on the activities as part of efforts to raise awareness on breast cancer which is killing many people especially women in Ghana and urged the general public to go for regular screening.

The study was presented Tuesday at the U.K.'s National Cancer Research Institute (NCRI) annual cancer conference, in Glasgow, Scotland. Still more studies must be done to understand the connection between waking up earlier or later in the day and breast cancer diagnosis.

Now, there's evidence to suggest that the gene mutation may be linked to an increase risk of breast cancer, with night owls more at risk than larks.

Researchers then mapped the genetic variations between the earlier risers and the night owls and compared it with that to the risk of developing cancer.

"Previous research has looked at the impact of shift work, but this is showing there may be a risk factor for all women". They used a clever new way of analysing data - called Mendelian randomisation. Around 4% of U.S. cancer deaths were linked to drinking alcohol and the Breast Cancer Now charity warns that any alcohol intake increases the risk of breast cancer.

AXA Mansard, a member of AXA, a global leader in insurance and asset management, said it joined in the observance of the concluded breast cancer awareness.

She tells 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".

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

Dr Rebecca Richmond, one of the researchers from the University of Bristol, told the BBC: "The findings are potentially very important because sleep is ubiquitous and easily modified".

Age and family history are some of the main risk factors for breast cancer. Starr, a breast cancer survivor, who is a part of the corporate sponsor Houlihan Lawrence, has been involved in these types of marches for years.

"In terms of the implications of the research, it supports existing evidence that sleep patterns influence cancer risk, but it remains unclear how individual preferences for early or late rising interact with actual sleep behaviours", Moorthie wrote in an email.
