Hi Vicky, There are many things to consider in a study such as this. Before we alarm everybody about the horrors of osteosarcoma in neutered males lets consider the fact that this cancer is prevalent in Rotties and that one has to take into consideration the pedigrees of all the dogs in the study. How were they related, were they a totally diverse group, what was the relationship between the affecteds and non-affecteds and the percentage ratio compares to those related but not neutered. Age of onset of disease and so the comparison goes on.
