Famous Dr Francis Roe Quote
Elsewhere, I have pointed out that overfeeding of rats profoundly influences the incidence particularly of endocrine tumours. Furthermore, endocrine tumours and tumours of tissues, such as the breast and uterus, which are very directly under sex-hormone control, constitute a very high proportion of the tumours observed in most carcinogenicity studies in rats. [Comparing] the incidences of tumours in these categories in men and women with those in male and female rats... [shows] the differences between the two species are sufficiently striking to make one wonder how appropriate the laboratory rat is as a model for man in terms of the spectra of tumours to which they are prone.
