Morning people less likely to develop breast cancer

Good news, morning larks - research shows that women who feel at their most awake in the hours before lunch are 40 percent less likely to develop breast cancer than late risers.

The researchers from the University of Bristol in England looked at 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 and found that women who prefer mornings have a 40% to 48% reduced risk of developing that type of cancer. The study also found that women who sleep more than seven to eight hours have a 20% increased risk for each additional hour after that that they slept.

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.

Their findings were presented at the 2018 National Cancer Research Institute (NCRI) conference in Glasgow.

Attendees of the event included hundreds of family members, sports teams, friends, and even those valiant survivors affected by breast cancer; most wearing sashes to signify their defeat against the cause.

Researchers looked at the DNA from a total of 410,000 women, based on whether they were lark or owl types. "We would like to use genetic data from large populations to further understand how disrupting the body's natural body clock can contribute to breast cancer risk", she said.

Out of the 400 000 women, 2,740 were breast cancer survivors and 149 064 were disease free.

Democrats also raised concerns about the appointment of Whitaker, 49, who will now oversee Mueller's probe. He also said there was no evidence Russian Federation interfered in the election at all.

Dr Emma Pennery, of the Breast Cancer Care charity, said: 'Changing your sleeping habits is not as easily done as other proven risk-reducing choices, as they're often part and parcel with jobs, parenting or other health conditions'.

Breast Cancer walks, such as this one, take place around the country and aid in finding a cure and raising awareness for this disease.

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

"Women need to talk to their doctors and the benefits of screenings, self-breast examinations and risk factors".

Dr Richmond and her colleagues are planning to investigate the mechanisms underlying the effects of different sleep characteristics on the risk of developing breast cancer.

However, cancer experts say modifying your sleep patterns probably won't have a significant impact on your cancer risk.
