Feline Mammary Fibroepithelial Hyperplasia: A Clinical Approach

Feline mammary masses are frequently suspected of being mammary tumours. Immediate attention is required as over 80% of mammary tumours in cats are malignant [1,2], albeit mammary masses in cats are less common than in dogs. However, prevalence of mammary tumours is highly variable with the geographic region, as it tends to be lower in areas where most cats are neutered at a young age. Due to the negative prognosis generally attributed to feline mammary tumours, little attention has been paid to benign mammary growths and mastectomy is still often performed to deal with feline mammary fibroepithelial hyperplasia.
