Having three drinks a day can increase the risk of breast cancer by 30%
Women who have three drinks a day increase their risk of breast cancer by a third, as much as smoking a whole pack of cigarettes. The type of alcohol does not change the effect; it is the quantity that causes the increased risk of developing the disease.
The research by US health maintenance association, Kaiser Permanente was revealed at the European Cancer Conference yesterday. It is the largest to date that makes the link between alcohol and breast cancer.
The study followed 70,000 women who were examined between 1978 and 1985. By 2004, 2829 participants had developed breast cancer. The results showed that women having between one and two drinks a day increased the risk by 10%, which then jumped to 30% for three drinks.
Dr. Arthur Klatsky, author of the report commented, ‘A 30% increased risk is not trivial. To put it into context, it is not much different from the increased risk associated with taking oestrogenic hormones (HRT).’ He also added that the findings could account for 5% more breast cancer cases a year.
