Smokers are at 8 times greater risk of developing Warthin's tumor than the general population.

Warthin's tumor primarily affects older individuals (age 60-70 years).

Warthin's tumor is highly unlikely to become malignant.

Though much less likely to occur than pleomorphic adenoma, Warthin's tumor is the second most common benign parotid tumor.

The most common of these include pleomorphic adenoma (70% of tumors, affecting predominantly females (60%)) and Warthin's tumor.

Not to be confused with Wharton's duct (submandibular duct) Warthin's tumor or Warthin tumour, also known as papillary cystadenoma lymphomatosum, monomorphic adenoma or adenolymphoma, is a type of benign tumor of the salivary glands.
