People who are active in their spare time could be at a lower risk of developing a range of cancers, including lung cancer, according to a new study.
The research, published in the Journal of the American Medical Association, used data from 12 studies involving a total of 1.44 million people from the USA and Europe.
The studies had collected information from participants on the amount of physical activity they regularly did in their free time – such as walking, running and swimming. Researchers then followed up with the participants to check on the state of their health, and whether they went on to develop cancer.
After comparing this information, and accounting for other factors that could have an influence – such as weight, or whether a person smoked – the scientists found that regular physical activity seemed to lower the risk of developing 13 cancers, including lung cancer.
Further research is needed to see exactly why exercise might help to prevent us from getting cancer, but the finding emphasises the importance of an active lifestyle.
