Physical activity is the answer for lot of our problems of the modern day struggles. A meta analysis review - reviewing a lot of studies has inferred a positive influence of optimum physical activity in breast cancer survival.
The study is a systematic review and meta-analysis of 36 studies that investigated the relationship between physical activity and breast cancer survival included a total of 23,428 breast cancer patients with a follow-up period ranging from 2.4 to 18 years.
The studies included in the analysis used a variety of physical activity measures, such as self-reported physical activity, accelerometer data, and physical fitness tests. The types of physical activity assessed also varied, including aerobic exercise, resistance exercise, and walking.
The authors conducted a meta-analysis of the available data and found that higher levels of physical activity were associated with better breast cancer-specific survival (hazard ratio (HR) = 0.81, 95% confidence interval (CI) = 0.76-0.87), overall survival (HR = 0.82, 95% CI = 0.78-0.86), and disease-free survival (HR = 0.84, 95% CI = 0.79-0.89). The protective effect of physical activity was more pronounced in women with hormone receptor-positive breast cancer.
The authors also conducted subgroup analyses to investigate potential sources of heterogeneity among the studies. They found that the relationship between physical activity and breast cancer survival was consistent across different types of physical activity, different measures of physical activity, and different patient populations.
Overall, the findings of this study suggest that
Higher levels of physical activity are associated with better breast cancer survival outcomes.
These results have important implications for promoting physical activity among breast cancer survivors, but further research is needed to clarify the optimal amount and type of physical activity for breast cancer survival.
