Daily glass of wine raises risk of breast cancer in women - The Guardian

US study finds light drinking linked only to minimal increase in risk of all cancers but daily drink raises chances of breast cancer for women significantly

Drinking one glass of wine a day increases a woman’s chances of getting breast cancer, according to new research.

Alcohol is a known risk for a number of cancers, including colorectal, liver, larynx and oesophageal cancer, and most attention has been paid to heavy drinking. A large study in the United States has now looked specifically at the link between alcohol and cancer in light to moderate drinkers.

The research, published online by the British Medical Journal, found that light drinking, defined as up to one standard drink a day for women and two drinks for men, was linked only to a minimal increase in risk of all cancers. However, a daily glass of wine raised the chances of breast cancer for women significantly – whether or not they smoked, since smoking is not linked to breast cancer.

The study was carried out by a team of researchers based at Harvard TH Chan School of Public Health and Brigham and Women’s Hospital in Boston. They used data from two large US studies – the Nurses Health Study for women and the Health Professionals Follow-up Study for men. These tracked the health of 88,084 women and 47,881 men for up to 30 years. The researchers assessed the risk of total cancer as well as known alcohol-related cancers including cancer of the the colorectum, female breast, liver, oral cavity, pharynx, larynx and oesophagus. - Read More
