Practicing physical activity has an immunotherapy effect that prevents the appearance of cancers and, in the case that they have already appeared, helps to slow down their progression. It is the conclusion reached by researchers from the University of Copenhagen (Denmark) who have studied the effects of physical activity in mice bred to develop melanomas, lung cancers and liver cancers.

Previous research had observed that people who practice physical activity have a lower risk of different types of cancer than the whole population. Likewise, it has also been observed in different cancers that physical activity is related to fewer relapses after treatment and with a better evolution of patients. However, the reason why the exercise has an antitumoral effect was unknown. More information.
