Oral tumours can occur in both dogs and cats. As soon as you observe a tumour, perform diagnostic tests, including cell examination (cytology and/or histopathology) to determine whether the tumour is malignant or benign.
Malignant Oral Tumours
Malignant oral tumours usually carry a guarded to poor prognosis in dogs and cats.
Treatment depends on many variables, including size, location and classification as benign or malignant. The goal when performing tumour removal should be to include a wide surgical margin around the lesion — 1 cm for benign lesions and 2 cm for malignant lesions.
Benign Oral Tumours
Benign oral tumours can often be surgically removed resulting in a cure.
Epuli are common oral benign tumours of the periodontal ligament. Some are locally aggressive (acanthomatus) while others are not (fibromatus, ossifying). Depending on the amount of growth, extraction of the tooth of origin as well as adjacent teeth is often indicated.
