The Los Angeles Times “Booster Shots” blog reports that “even moderate levels of physical activity – during childbearing years or after menopause – may reduce breast cancer risk,” according to a new study.
The Time “Healthland” blog reports that the researchers “found that women who exercised about two hours a day five days a week were about 30% less likely to develop breast cancer than less active women.”
The investigators also found that “the intensity of the exercise didn’t seem to matter; all it took was moderate physical activity, which could include gardening, walking or doing household chores, for the women to benefit.”
The Boston Globe “Daily Dose” blog reports, “Among obese women with a body mass index (BMI) above 30, those who exercised the most had a lower risk of breast cancer compared with those who remained inactive.”
On its website, ABC News reports, “Physically active women who gain more than 11 pounds after menopause are at a higher risk of developing breast cancer, though it’s lower than for post-menopausal women who gain a similar amount of weight who don’t exercise.”
Meanwhile, “obese women who exercised had about the same risk as normal-weight women who did no physical activity at all.”
HealthDay reports, “The risk reduction was seen mostly for hormone receptor-positive breast cancer, which is the most commonly diagnosed type among American women.”
