A recent huge study reminds us how good exercise can be.
A pooled analysis of data from studies looking at 1.4 millions adults indicates that exercise reduces the risk of over 10 cancers, including bladder, kidney and stomach.
The way it works is thought to be related to weight reduction, DNA repair , alteration of hormonal levels and reduced inflammation.
For most of the cancers, the risk reduction was about 20% or more, and rises up to 42% for esophageal cancer.
So while this study doesn’t prove that exercise directly reduces the risk of cancer - it is only a report of an observed association -, it shows a link strong enough to motivate us to move as frequently as we can.
Find a sport you enjoy, and practice as often as you can !
