Drinking coffee has become a part of many Chinese people's lives, but many female friends love to drink coffee, but they are also worried that caffeine will harm the breasts. Does caffeine increase the risk of breast cancer? In addition, if you stay up all night and work and rest regularly, is the risk of breast cancer higher?
Chang Jinjian, a famous breast cancer doctor at National Taiwan University, pointed out that according to the 2013 academic research on the relationship between coffee, chocolate, tea and other caffeine and breast diseases, it is pointed out that high caffeine intake is not related to the formation of breast fibrocysts and breast cancer.
In fact, there is no research report showing that caffeine can cause breast cancer. Therefore, drinking coffee is not prohibited for breast cancer patients. However, patients receiving aromacyclase inhibitors are advised not to drink because of the possibility of bone loss. Coffee, because drinking coffee has a poor absorption of calcium. If you really like to drink it, you must pay attention to calcium supplementation, get more sunlight, and exercise more.
The World Health Organization has removed coffee from a class 2B carcinogen, downgrading it to a class 3 (cannot be classified as a human carcinogen), however the World Health Organization says,
In addition, Zhang Jinjian reminded that women who often stay up late or have irregular work and rest really need special attention. The International Agency for Research on Cancer (IARC), the World Health Organization's cancer prevention agency, officially listed it as a possible carcinogen in December 2007.
Richard Schneider, professor of cancer epidemiology at the University of Connecticut Health Research Center, USA Stevens, research published in 1987Alleged that staying up late to work is prone to breast cancer. He analyzed that after the 1930s, the sudden increase in breast cancer among women was mainly due to the fact that the world entered the information age, and many people began to work at night.
Women who work night shifts are more exposed to fluorescent light, which suppresses a hormone produced at night, melatonin; when melatonin levels in the blood are reduced, the incidence of breast or other cancers is also reduced The risk of breast cancer increases among women working night shifts, especially among female airline flight attendants. Of course, other women working at night have the same situation.
For this reason, maintaining normal work and rest and regular sleep, not staying up late or reversing day and night, should be the best way of health care for all female friends.
