|Title||Exercise reduces risk of several cancers|
|Date||2 March 2020|
|Full Story||While it has been known for some time that regular exercise provides many benefits on cardiovascular health, diabetes and on reducing risk of cancers such as breast and colon, a recent large meta-analysis of prospective studies with a total of 755,459 individuals has shown reduction in other cancers and that there may be a dose-response relationship.
Information was analysed from 9 studies that had reported physical activity and followed up for 10.1 years for cancer diagnosis. Median age, 62 years, range, 32-91 years.
Individuals who achieved the recommended 2.5 to 5 hours per week of moderate intensity activity had a statistically significant lower risk of 7 cancer types: colon (greatest effect in men), breast, endometrial, kidney, myeloma, liver and non-Hodgkin lymphoma (greatest effect in women).
While limitations apply in that these were observational studies, rather than randomised trials, and the information analysed relied on self-reporting, this does provide yet more information about the significant benefits of exercise for all. Let’s get walking!
