Adherence
Increasing physical activity levels after menopause, even if one was previously inactive, reduces breast cancer risk compared to remaining sedentary.
If you were inactive before or around menopause, you can still lower your breast cancer risk by becoming moderately active now. You do not need to be a high-level athlete. Aim for about 30 minutes of walking at an average pace on most days of the week. This change in behavior can provide a protective benefit even if you were previously sedentary.
Compared with women who were least active at menopause and through follow-up... women who increased activity were at lower risk (>=9 MET-h/wk at menopause and >=9 MET-h/wk during follow-up: HR, 0.90; 95% CI, 0.82-0.98).
Why this rating
Same high-quality cohort data as N1, specifically analyzing the 'change' variable.
