A new study from the AICR and WCRF showed that drinking a daily glass of alcohol or any other small quantity can lead to an increased risk of developing breast cancer in women of all ages. At the same time, long and vigorous exercising can help decrease these same risks.
This latest report is a meta-study which analyzed and compared data from 119 studies from all over the world. These included over 12 million women and reports on some 260,000 cases of breast cancer. This is the first study of its kind since 2010, and it looked at how weight, dietary habits, and exercising affect breast cancer risks.
A Daily Glass of Alcohol Increases Breast Cancer Risks, but Intense Exercising Decreases Them
According to the report, a daily glass of alcohol, be it either beer or wine, of about 10 grams, can increase breast cancer risks in all women. A standard drink comes with 14 grams of alcohol, in comparison. For pre-menopausal ladies, risks can grow by 5 percent. In post-menopausal women, the chances of developing the disease rise by 9 percent.
The study team also looked at the physical activity levels of women of all ages. More exactly, it split them into two groups, according to their exercising habits.
Pre-menopausal women with the most active lifestyle presented a 17 percent lower risk of developing breast cancer when compared to their least active counterparts. For post-menopausal women, the percentage was slightly lower, coming to a 10 percent decreased chance of cancer.
Moderate activity levels also seem to have a positive effect and to help reduce breast cancer risks by about 13 percent when compared to the least active groups.
“There are no guarantees when it comes to cancer, but it’s empowering to know you can do something to lower your risk,” says Alice Bender.
