Ingesting just one glass of wine or different alcoholic drink a day raises breast cancer risk, finds a new study by the American Institute for Cancer Research (AICR) and the World Cancer Research Fund (WCRF).The report additionally revealed, for the first time, that greater physical activity similar to walks or speedy bicycling decreases the danger of both pre- and post-menopausal breast cancers. Robust evidence demonstrated an earlier discovering that moderate physical activity decreases the hazard of post-menopausal breast cancer, the most long-established type of breast cancer.
According to Anne McTiernan, MD, PhD, a lead author of the report and cancer prevention expert at the Fred Hutchinson Cancer Research Center, It can be confusing with single studies when the findings get swept back and forth. With this comprehensive and up-to-date report the evidence is clear: 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.
Researchers from the Diet, Nutrition, Physical Activity and Breast Cancer study systematically collated and evaluated the scientific research done globally on how diet, weight and physical activity have an effect on breast cancer risk within the first such overview since 2010. The record analyzed 119 studies, together with information on 12 million females and 260,000 cases of breast cancer.
Alcohol and breast cancer risk
The study found strong evidence that drinking the same as that of a small glass of wine or beer a day (about 10 grams alcohol content) increases pre-menopausal breast cancer risk by 5 percent and post-menopausal breast melanoma risk by 9 percent. A regular drink is 14 grams of alcohol.
For greater physical activity, pre-menopausal women who had been the most active had a 17 percent lower risk and post-menopausal women had a 10 percentage decreased risk of developing breast cancer compared to those who have been the least energetic. Total moderate activity corresponding to walks and gardening, is linked to a 13 percent reduced risk when comparing the most versus least active women.
In addition the record confirmed that:
- Being obese or overweight raises the risk of post-menopausal breast cancer, the most long-established variety of breast cancer.
- Mothers who breastfeed are at reduced risk for breast cancer.
- Greater weight gain increases risk of post-menopausal breast cancer.
Breast cancer is probably the most common cancer in US women with over 252,000 new cases estimated this year. AICR estimates that one in three breast cancer cases within the U.S. might be averted if women did not drink alcohol, have been physically active and maintained a healthy weight.
It has also been shown that there are links between diet and breast cancer risk.
There was once some evidence — despite the fact that it is constrained — that non-starchy vegetables lowers the chance for estrogen-receptor (ER) negative breast cancers, less usual types but tougher to deal with form of tumors.
Limted proof also links dairy, diets high in calcium and foods containing carotenoids to lowering the risk of some breast cancers. Carrots, apricots, spinach and kale are all foods high in carotenoids, a group of phytonutrients studied for their health advantages.
These links are exciting however more study is required, says McTiernan. She claimed that, The findings indicate that women may get some benefit from including more non-starchy vegetables with high variety, including foods that contain carotenoids. That can also help avoid the common 1 to 2 pounds women are gaining every year, which is key for lowering cancer risk.
