Introduction
摘要
The field of oncology in companion animals has expanded tremendously in the last few decades. Cancer risk has been shown to be the largest health concern among pet owners [1] and for good reason. Cancer is the leading cause of death in pet dogs over the age of 10 [1, 2]. Cancer is also a leading cause of death in people, with the lifetime risk of cancer reported as 38.5% in developed countries, with men and women at similar risk of developing cancer (26.27% and 23.96%, respectively) [3]. Cancer, as a health concern, is agnostic of species, and common themes exist among affected mammals.
