edit Lip Cancer

• Lip is most common single site for oral cancer.
• Carcinoma of lower lip more common + grows slower.
• In patients 50–70 years old, mostly men.
• Lesions arise on vermillion border of lower lip, appear as non-healing ulcers, painless.
• Larger lesions metastasize to local sub-mental or submandibular lymph nodes.

edit Etiology

Lip cancer is multifactorial dissease. Factors that increase the risk of getting lip cancer are especially:

• Tobacco use;
• pipe smoking ;
• thermal injury;
• lip trauma;
• poor oral hygiene;
• mechanical irritants ;
• immunosuppression;
• UV light;
• decreased antioxidants in diet.

edit Diagnosis

• Incisional biopsy (includes portion of lip lesion + portion of normal appearing tissue).
• Radiographic: unnecessary for early stage tumors; for advanced tumors that adhere to or invade adjacent mandible.

edit Types

• Squamous cell carcinoma: from epithelial lining of oral cavity, one sided, shallow ulceration + crustening, slow spread.
• Basal cell carcinoma: less aggressive, destroys tissue locally, upper lip.
• Minor salivary gland cancers: upper lip, rubbery nodules, ulcerated.

edit Treatment

Surgical excision

Remove carcinoma within 2 cm margin of normal tissue.

Radiotherapy

• Teletherapy= external beam,
• Plesiotherapy= implanted radioactive seeds, needles.

Cryotherapy

For minor tumors.
