Breast cancer is unfortunately prevalent not only among humans, but also in our feline friends.
Just like with people, mammary cancer is very aggressive in cats, and they have the best chance of survival if caught early.
“Eighty-five percent of mammary tumors found in cats are malignant, and more that 80 percent will eventually spread to other locations in the body, such as the lymph nodes, lungs, bone and internal organs,” said Dr. Jacqueline Bloch, medical oncology resident at the Texas A&M College of Veterinary Medicine & Biomedical Sciences.
It is found that Siamese and domestic shorthair cats are more at risk for mammary tumors.
“Siamese are especially prone to developing them at a relatively young age,” Bloch said. “The average age is 10 years in other cats.”
However, it is a risk for any cat to develop a mammary tumor, and like with other cancers, it is important to get a proper diagnosis.
“Mammary tumors in cats are best diagnosed by a biopsy. This helps us to give prognostic information to the owners as well as diagnosis,” Bloch said. “Sometimes we can obtain diagnosis by a relatively non-invasive needle biopsy.”
