Feline Mammary Tumours

Among common tumours in cats, mammary tumours rank third in incidence, and approximately 90% are malignant!

Why do cats develop mammary tumours?

Unspayed female cats experience continuous heat cycles, leading to hormonal fluctuations that repeatedly stimulate mammary tissue, greatly increasing the risk of tumours.

How can we prevent this for our cats?

"Early spaying"

• Spaying a female cat around 6 months to 1 year of age can effectively reduce the risk of mammary tumours.

“Recognize high-risk breeds”

• Data shows that Siamese cats have a higher probability of developing mammary tumours compared to other breeds, and the onset may occur at an earlier age.

“Annual health check-up

• For middle-aged to senior female cats (particularly unspayed ones), regular veterinary check-ups are essential. As cats age, the likelihood of tumours increases; therefore, early diagnosis and treatment can significantly improve the chances of a cure.
