A Critical Review.” BMC Cancer 15 (1): 792. doi:10.1186/s12885-015-1782-z.
Background
Carcinogenesis affects not only humans but almost all metazoan species. Understanding the rules driving the occurrence of cancers in the wild is currently expected to provide crucial insights into identifying how some species may have evolved efficient cancer resistance mechanisms. Recently the absence of correlation across species between cancer prevalence and body size (coined as Peto’s paradox) has attracted a lot of attention. strattera 40mg
Indeed, the disparity between this null hypothesis, where every cell is assumed to have an identical probability to undergo malignant transformation, and empirical observations is particularly important to understand, due to the fact that it could facilitate the identification of animal species that are more resistant to carcinogenesis than expected lasix 20mg. Moreover it would open up ways to identify the selective pressures that may be involved in cancer resistance. However, Peto’s paradox relies on several questionable assumptions, complicating the interpretation of the divergence between expected and observed cancer incidences. Clomid 50mg
