Lip cancer is the most common malignant lesion of the oral cavity, constituting 25-30% of all oral cavity cancer cases and is the second most common malignancy of the head and neck overall (after cutaneous malignancy).
Unlike other sub-sites of the oral cavity, sun exposure is a well established risk factor for development of lip cancer. This helps explain why 90% of lip cancers occur on the lower lip, since it has a higher level of sun exposure compared to the upper lip which is shielded by the nose and is angled slightly downwards.
