When it comes to dogs, mammary tumors are the most common forms of cancer in females. Now, though, researchers have taken a closer look at this breast cancer and the findings may help improve our understanding of the development of cancer not only in dogs, but also in humans.

The researchers then compared the incidence of specific genes in different groups of English springer spaniels with and without mammary tumors. They found that variants of the estrogen receptor gene are associated with the risk of developing these tumors in dogs. This, in turn, reveals a little bit more about cancer development in general.

They also discovered that as the number of mutations and the number of aberrations increased, the more malignant the tumors turned out to be.
