A new study indicates that consuming one alcoholic drink each day can increase a woman’s breast cancer risk. Researchers found that a small glass of beer or wine, which contains roughly 10 grams of alcohol, can increase a premenopausal woman’s cancer risk by 5 percent.
The risk goes up by 9 percent in case of postmenopausal women. According to the study’s lead author Anne McTiernan, both figures are significant. McTiernan is an expert in cancer prevention at the Fred Hutchinson Cancer Research Center.
The American Institute for Cancer Research, or AICR, made the World Cancer Research Fund report available to the public.
One Drink A Day Linked To Breast Cancer Risk, Says Report
Apart from establishing the fact that even one drink a day increases breast cancer risk, the WCRF report found that moderate exercise can help lessen breast cancer risk in both postmenopausal and premenopausal women.
“Having a physically active lifestyle, maintaining a healthy weight throughout life, and limiting alcohol —these are all steps women can take to lower their risk,” McTiernan noted.
To validate their hypothesis, the researchers examined and evaluated data from 119 studies. These studies contained data from more than 12 million women, including roughly 260,000 women suffering from breast cancer.
Limit Drinks To Reduce Breast Cancer Risk?
Physicians and other health officials who are not associated with this study are of the view that the research does not provide new insight into the control or prevention of breast cancer, as the link between alcohol consumption and breast cancer was established in the past.
However, they noted that this study will nevertheless present more data about the exact alcohol amount, which can increase breast cancer risk. McTiernan added that wine, beer, and spirits are all responsible for increasing breast cancer risk.
On an average, the AICR recommends just one drink a day for women. However, the AICR notes that it would be best if one completely abstains from alcohol consumption. For women who are concerned about breast cancer risk, low-calorie drinks such as sparkling water, coffee, tea, or water can be a good alternative to alcohol.
Exercise In Place Of Alcohol
The researchers also uncovered that that women who are yet to hit menopause and exercised well had a 17 percent lower risk of developing breast cancer vis-à-vis those who are not that active. Breast cancer risk in postmenopausal women who exercised vigorously decreased by 10 percent.
Women in general, who exercise moderately have a 13 percent lower risk of developing breast cancer compared to those who do not exercise at all.
