Early pregnancy women are at risk of breast cancer, says FOX 4 Kansas City WDAF-TV



In the early stages of research, women in the early stage reduce the risk of breast cancer rather than in the evening. One in 100 women who consider themselves morning-time has developed breast cancer, compared with both 100 women who call themselves eveningners.

Previous studies have reported malignant neoplasms associated with human body and sleep patterns, and Britain's researchers have sought to explore the sleep patterns and any genetic factors based on it.

In mornings or evenings, there is a statement of theirs (which defines their advantages) More than 180,000 women have been trained by Robert Richmond, UK's Cancer Research UK Integrative Cancer Epidemiology Program and Bristol University Epidemiology Officer, and at the NCRI Cancer Conference in Glasgow on Tuesday.

The Richmond team analyzed genetic guidelines because someone was morning or night Over 220,000 women will be able to find out if they have cause-and-effect relationship with breast cancer.

This type of statistical model, called Mendelian Randomization, showed that people with a higher gene may be more likely to develop breast cancer from 220,000 to 48% of the research participants.

The second analysis demonstrated a similar tendency towards early developmental women with a risk of 40% of breast cancer, using self-reported data on the sleepiness of 180,000 participants. Richmond has shown that the change is related to technical differences.

According to the Mendelian Rantomization Assessment, breast cancer patients had more than seven or eight hours sleeping a day with a slight increase in breast cancer and an additional 20% sleep without an hour.

But the team notes that many factors are involved in the development of breast cancer and that these numbers are not absolute. Also, conclusions can not be applied to populations, as many women have European names.

"Sleep may be an important factor in breast cancer, but it's not as big as other dangerous factors, such as BMI or alcohol," Richmond said.

American Society for the Dangerous Disease About 45% of cancer cases in the United States are related to various risk factors, such as tobacco smoke, body weight gain, red and processed meat, and physical inactivity. Approximately 4% of US cancer deaths are related to alcoholism, and nowadays, breast cancer is causing the risk of any breast-feeding breast cancer risk. Obesity in women in the UK should be the cause of breast cancer prevention.

"We know that sleep is important for our health," Richmond said. "These studies have potentially political consequences for improving health and affecting the habits of sleep in order to reduce the risk of developing breast cancer among women."

Our ring rhythms or body functions, such as body clocks, sleep patterns, blood pressure and metabolism, increase the risk of cancer and other illnesses when they are damaged.

The Richmond team conducted a genetic analysis, hoping to explore the potential causes and effects of this relationship. However, according to experts, there should be a lot of studies and the existing conclusions are not widely used.

"The statistical method used in this study does not allow Mendel's Randomization to be the cause," says Dipen Jill, a clinical researcher at the Imperial College in London. "For example, sleep patterns may affect other neurons that affect breast cancer. In such a scenario, sleep patterns may be associated with the risk of breast cancer, but not directly. "

Cambridge University doctor Steven Burgess is also uncertain about the mechanism for interpreting this link.

"The authors do not show any biological mechanisms, they have the advantage of choosing sleep time that may affect breast cancer. Another limitation – the advantage of sleep time (chrono- phy) does not have samples of different sleep patterns, such as self-reported and night-shift workers. "

The study has not yet been published in a medical journal. Gill still denied the views of other experts in this area.

Not as big as other factors

Richmond 48% lower risk was defined in "extreme" cases, where people have chosen Morning Morning Day Morning Morning Mornings from Morning Mornings to Morning Mornings From Five Moral Morals. known evening.

"Sleep may be an important factor in breast cancer," he said. But it's not a big risk factor, like other well-established factors like weight or alcohol consumption, "Richmond said.

Richmond said: "The results of night bangs should not be bothered." "In order to reduce the risk of breast cancer, women would have to get up early".

There is a theory that sleep can have an impact on oncological diseases, which suggests that at night it will lead to hormonal damage to artificial light.

Dr. Sovmie Mouretie, a senior policy analyst at the PHG Foundation who did not take part in the study, said the main force of the study was "to use many ways to research relationships between sleep and breast cancer." it is necessary to show the sequence of their results ".

"As a result of the study, sleep patterns support evidence that affects cancer, but it is unclear how it can affect the behavior of individual sleep," says Moorthie.
