Physical activity and cancer

In this article authors found that “Cancer incidence was not related to lifestyle”.
Taking into account (i) that physical activity can not influence all type of cancer in the same way, and (ii) that authors considered overall cancer cases without analysis of particular types of cancer, this finding should be taken with caution. There are numerous studies confirming protective and therapeutic effects of physical activity against breast and prostate cancer. We recently suggested possible molecular mechanism underlying this phenomenon (Veljkovic et al. Physical activity and natural anti-VIP antibodies: potential role in breast and prostate cancer therapy. PLoS One. 2011;6(11):e28304. doi: 10.1371/journal.pone.0028304 ), but the proposed molecular mechanism does not concern other types of cancer. For this reason, for correct interpretation of results of this valuable study in terms of effects of the lifestyle on cancer, authors should report all type of cancers which were included in this study.
