Lip cancer

Carcinoma of the lip is a cancer that occurs in the mucosa of the red lips. According to the UICC classification, the inner lip mucosa should be buccal mucosa cancer; those with dermal origin should be classified as skin cancer; lip cancer should be limited to the primary lip red mucosa. In view of this, lip cancer has been separated from oral cancer; however, in a broad sense, there are also people who claim to classify lip cancer as oral cancer.
