Lip cancer is a type of oral cancer that most often affects the lower lip, and its common symptoms include a sore, crust, or ulcer that does not heal within two to three weeks, a scaly or rough patch, a lump or thickening, bleeding, or numbness. The biggest risk factors are long-term sun exposure and tobacco use. Most lip cancers are squamous cell carcinomas that are very treatable when found early, usually with surgery, sometimes followed by radiation, and routine oral cancer screening includes a careful look at your lips.
Many lip sores are harmless, such as cold sores, chapping, or small injuries, and they heal within a couple of weeks. Persistence and change are the signals that deserve an exam.
A common precancerous condition called actinic cheilitis, a dry, scaly lower lip from sun damage, is worth having checked, because it can progress if left untreated.
Your dentist in Kitsilano can examine lip changes and refer you for a biopsy if needed. Regular preventive dental visits provide a baseline, and procedures may be arranged through oral surgery or skin and head and neck specialists. You can find our clinic on Google Maps.

Real Patient Scenarios
