The researchers did note, the study has limitations, and they couldn’t detect the small effect the timing of exercise might have with certainty.
This finding of this study is thought to be important because of the high numbers who develop cancer and the significant number who die of the disease.
For example, in the USA, scientists estimate by the end of 2020, 1,806,590 people will receive a diagnosis of cancer – 606,520 will die from the disease.
Considering the large number of people who develop cancer, a change as small as changing the time a person exercises could have a significant contribution to reducing the impact of cancer across whole populations.
