title: Snus (nass) and oral cancer: A case series report.
abstract: Snus (nass) is a form of snuff used in a similar manner to American dipping tobacco, but it does not typically result in a need for spitting. Possible hazards associated with this material include malignant and premalignant lesions in the oral cavity and gastrointestinal tract. The use of smokeless tobacco has increased in the Middle East in recent decades, particularly among teenagers and young adults. Therefore, practitioners must be able to recognize malignant and premalignant lesions. Although, an estimated 10-25% of the world's population uses smokeless tobacco, this practice is virtually unknown in Iran. The aim of this study is to report a series of cases of squamous cell carcinoma and verrucous carcinoma occurring in the users of snus, who referred to the Department of Oral Medicine in Kerman Dental School.
