Oral tumors in dogs and cats

Oral tumors (growths) are very common in dogs and cats. These pet oral growths can be benign or malignant (cancerous). In many cases pet oral tumors are treatable with good long-term results. Correct treatment depends on obtaining a small biopsy sample to identify the particular tumor type, determining if the tumor has spread to the lungs or lymph nodes, and obtaining detailed dental radiographs to show how far the tumor has spread locally. After this information is gathered, a detailed treatment plan can be formulated. As part of his training for board certification, Dr. Woodward received extensive education in treating oral tumors. He has performed many oral surgical procedures for the treatment of oral tumors.

Early diagnosis and treatment dramatically improve the success rate of treatment. When allowed to grow unchecked, some tumors cannot be treated effectively.
