Definition:
Lip cancer pertains to any type of carcinoma affecting the lip. Lip cancer is considered as a major form of oral cancer and is often characterized by visible ulcers that won't heal over time.
Diagnosis:
Lip cancer may be diagnosed with a combination of any of the following procedures: biopsy, computed tomography (CT or CAT) scan, ultrasonography, magnetic resonance imaging (MRI), as well as endoscopic procedures to view the mouth, nasal cavity, esophagus, throat, and larynx.
Treatment:
Treatment for lip cancer may involve surgery to remove the cancerous mass, radiation therapy, and chemotherapy.
Symptoms and Signs:
Lip cancer symptoms tend to develop slowly and may sometimes resemble those of other conditions. Common signs of carcinoma in the lips include: initial weakening of the line between the red vermilion of the lip and the white skin below the lip; formation of small scaly areas around the lips; soreness or red patches on gums, tongue, and lining of the mouth; lumps or ulcer-like patches around the mouth; swallowing or chewing difficulties; voice changes; bleeding of the lip; and discolored lumps.
Causes:
Lip cancer, or oral cancer in general, is often caused by frequent tobacco use and excessive alcohol consumption, as well as certain medical conditions such as leukoplakia and erythroplakia. In addition, too much exposure to sunlight is also believed to play a role.
