Mammary tumors are one of the more common tumors in cats. These tumors are most commonly noted in female cats that are not spayed or in cats spayed later in life. Malignant mammary tumors account for approximately 85% of mammary tumors in cats and are most commonly adenocarcinomas. Benign tumors are less common and are most commonly due to dysplasia or adenomas. The most important factors associated with mammary cancer in cats are the size of the tumor, the extent of the surgery used to control the cancer, and the histologic grade. Cats with larger tumors (> 3 cm), cats treated with lumpectomies and regional mastectomies, and cats with tumors showing high characteristics of malignancy tend to have shorter survival times and increased risk of cancer spread than cats with smaller tumors, lower characteristics of malignancy, and cats treated with more aggressive surgical resection. Chemotherapy may be used as an adjuvant treatment following surgery or as an option in cases where surgery may not be a feasible option.
