Bristol Scientists: Pregnant women who are at lower risk of breast cancer – BLITZ



Women whose biological clocks appear "early on" have less risk of breast cancer, say British scientists. According to a team at the University of Bristol, the reason for this is still unclear.

In their opinion, this conclusion is important because it can affect any woman at risk.

Experts say the results of the study were presented at a cancer conference in Glasgow following which confirm the importance of sleep in general for health.

Biological clock

Everyone has a biological clock that controls the way the body works in about 24 hours. It is also known as the circadian rhythm.

This affects everything – from sleeping to mood and even to the risk of heart attack.

However, every hour does not show the same.

Rare people get up early, their energy reaches their peak throughout the day and tired earlier in the evening.

Other types of people get tougher in the morning, their productivity reaches the highest level later and more go to bed later.

Is this in any way related to breast cancer?

Scientists think yes. They used a clever new way of analyzing data called Mendel's coincidence.

We examined 341 DNA fragments that control whether we are wound or night birds.

They then used this information to conduct an experiment with over 180,000 women from the Biobank project in the UK and nearly 230,000 women in a Cancer Association study.

The results show that the likelihood of breast cancer in women who are genetically programmed to be early waking less than in the second group.

Because these DNA fragments are born after birth and are not related to other known causes of cancer, such as obesity, it means that scientists are reasonably convinced that biologists have finger in cancer.

What is the effect?

Almost one in seven women in the UK suffer from breast cancer in their lives.

This study, however, focuses only on the small 8-year period of women's life.

For this period, according to the study, 2 out of 100 women who later go to bed and become later develop cancer, compared to one in 100 in the beginning.

Incredible, but the fact! You can survive without any of these human organs

If a person sleeps well, will he prevent cancer?

It's not that simple.

According to Dr. Rebecca Richmond, one of the authors of the study, it's still too early to give clear advice to women.

"We still have to find out what exactly puts a group of women at risk, we need to find a link," Richmond told the BBC.

Do scientists do it?

Science is never 100% sure, but the results of this study coincide with other findings.

According to the World Health Organization, the disruption of human biological hours due to shift work is probably associated with cancer risk.
