The study, which was conducted by a team of international researchers from Great Britain AndAmerica AndAustralia that also be Physical activity in the fight breast cancer Useful, it should be combined with reduced sitting times.
The researchers used genetic analysis to examine the causal relationship between physical activity levels and breast cancer risk.
The study, published in the British Journal of Sports Medicine, included more than 130,000 women, more than 76,000 of whom had breast cancer. “The Guardian” extracts of the same.
Previous studies had shown a link between physical activity and a lower risk of breast cancer, but a causal relationship could not be demonstrated.
Study lead researcher Brigid Lynch said: “There has always been little uncertainty as to whether physical activity actually reduces the risk of breast cancer or whether this relationship is confused by other factors.”.
The study found that if women exercised more, it was associated with a 41% reduction in the risk of developing cancer.
In premenopausal and postmenopausal women, physical activity (3 days per week) was associated with a 38% lower risk of cancer than no activity.
The lead researcher of the study said: “For every 100 minutes of session per day, we observed a 20% increase in the risk of developing cancer and a doubling of the risk of triple negative breast cancer, which is known to be more aggressive and difficult to treat.”.
Physical activity is believed to reduce the risk of breast cancer, as it reduces the amount of estrogen and androgen hormones circulating in the bloodstream, and a decrease in inflammation may be a factor in this direction.

The analyze, which was performed by a team of global researchers from Good Britain AndAmerica AndAustralia that also be Actual physical activity in the struggle breast cancer Helpful, it need to be blended with lowered sitting down times.
Scientists employed genetic evaluation to look at the causal connection amongst physical exercise amounts and breast most cancers threat.
The analyze, printed in the British Journal of Sporting activities Drugs, incorporated extra than 130,000 ladies, much more than 76,000 of whom had breast most cancers, and the Guardian newspaper printed excerpts.
Former research had proven a url amongst bodily action and a decrease danger of breast most cancers, but a causal partnership could not be demonstrated.
“There has generally been a tiny sum of uncertainty as to regardless of whether actual physical activity basically decreases the chance of breast most cancers or no matter whether this marriage is baffled by other factors,” mentioned research guide author Brigid Lynch.
The research located that if females exercised more, it was connected with a 41% reduction in the danger of developing cancer.
In premenopausal and postmenopausal women of all ages, bodily exercise (3 days per 7 days) was linked with a 38% lessen danger of cancer than no action.
“For each 100 minutes of classes for every working day, we observed a 20% maximize in the risk of establishing most cancers and a doubling of the danger of triple detrimental breast cancer, which is acknowledged to be additional intense and tricky to address,” he mentioned. the head of the research researcher.
Bodily exercise is thought to lower the threat of breast cancer, as it decreases the volume of estrogen and androgen hormones circulating in the bloodstream, and a lessen in irritation might be a component in this course.
