Bristol scientists: Pregnant women exposed to lower risk of breast cancer – BLITZ



Women whose biological watches have shown "early waking" are at a lower risk of breast cancer, say British scientists. According to a team at Bristol University, the reason for that is still unclear.

In their opinion, this discovery is important because it can affect every woman who is at risk.

Experts say the results of the study were presented at the Glasgow Cancer Cancer Conference, which they follow to confirm the importance of sleep as a whole for health.

Biological clock

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

It affects everything – since we are sleeping in our mood and even risk of heart attack.

However, every hour does not show the same.

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

Other types of people are getting harder in the morning, their productivity reaches the highest level later and prefer to go to bed later.

Is it in any way related to breast cancer?

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

They reviewed 341 DNA fragments that control whether early or nocturnal birds.

They then used that information to experiment with over 180,000 women from the Biobanks project in the UK and nearly 230,000 women in the Cancer Society study.

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

Since these DNA fragments are born at birth and are not related to other known cancer causes, such as obesity, it means that scientists reasonably believe that biologists have a finger in the cancer.

How big is it?

Almost one in every seven women in the United Kingdom suffers from breast cancer in their life.

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

For this period, according to the study, 2 out of 100 women who are late to bed later and later develop cancer, compared to one of the early 100 early years.

If a person sleeps well, will they prevent cancer?

It's not that easy.

According to Rebecca Richmond, one of the authors of the study, it is too early to give women clear advice.

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

Do the scientists?

Science is never 100% safe, but the results of this research are consistent with other findings.

According to the World Health Organization, termination of biological clocks by people for work is probably associated with cancer risk.
