What is it?
In animals, as in humans, cancer is defined as uncontrolled cell proliferation.
It is therefore not a single disease but there are several types of cancers that concern different types of cells or organs, which manifest themselves in different clinical forms and correspond to several etiologies.
We also talk about genetic diseases since they are caused by mutation accumulations that can lead to modify or even eliminate the mechanisms of control and regulation of cell growth.
These are not hereditary diseases (i.e. they are not transmissible to the offspring) but there are strong racial predispositions that explain that some forms of cancer are found more frequently in some pets. And as in humans, exposure to substances or a carcinogenic environment plays an important role in the occurrence of cancers.
