Most oral growths are benign. Warts, candidal infections, and repeated trauma are common causes of benign growths. Use of alcohol and tobacco and oral HPV infection are risk factors for cancer. Because cancer is difficult to diagnose by inspection, biopsy is often necessary.

What is the most common malignant tumor of the oral cavity?

Squamous cell carcinoma* is the most common malignant neoplasm of the oral cavity. Tobacco and alcohol use have been identified as risk factors, but squamous cell carcinoma can occur in patients with no known risk factors.

How common is oral fibroma?
