Doing housework and gardening reduces the risk of developing breast cancer. Research has shown that moderate amount of physical activity helps maintain health. Even activities like walking the dog and doing household chores can reduce the risk of developing breast cancer by 13%.
"Exercise can include anything that leaves you slightly out of breath like doing the gardening, walking the dog or housework. Small changes in your daily routine can make all the difference, like taking the stairs instead of the lift or walking some of the way to work, school or the shops, and add up over the course of a week."
