Lip Cancer
Lower lip squamous cell carcinoma · Vermilion lip cancer · Actinic cheilitis | ICD-O-3 C00 (grouped with C02–C06 in some GLOBOCAN tables)
Lip cancer is usually a squamous cell carcinoma of the dry red part of the lower lip, caused mainly by cumulative ultraviolet radiation. It is unusually common in Australia, New Zealand, Papua New Guinea and parts of Southern/Eastern Europe among fair-skinned outdoor workers. Small tumours are highly curable with limited surgery that preserves lip function.
Lip cancer is grouped statistically with oral cavity cancer (C00–C06), but its causes and behaviour are different from intraoral cancer: chronic sun exposure rather than tobacco or areca nut is the main driver. The precursor lesion is actinic cheilitis — persistent dryness, scaling and fissuring of the lower lip — which is why the lower lip, receiving more direct sunlight, is affected far more often than the upper lip.
Because the lesion is visible, lip cancer can be found early. A sore, crust or thickened patch on the lip that does not heal within a few weeks should be biopsied. Treatment is usually surgical excision with reconstruction of the lip, with neck dissection or radiotherapy reserved for larger or node-positive tumours.
Where in the world is lip cancer common?
about 32,200 new lip cancer cases (C00) worldwide were estimated worldwide in 2022 (male ASR 0.5 and female ASR 0.2 per 100,000; 4.2% of all lip/oral/pharyngeal cancers in 2022).
GLOBOCAN groups lip with oral cavity (C00–C06): 389,846 new cases at ASR 4.0 per 100,000 in 2022.
| Region / country | What the data show |
|---|---|
| Papua New Guinea & Melanesia | Lip cancer accounts for 26.5% of the region’s lip/oral/pharyngeal cancers. The highest ASRs worldwide are reported in Papua New Guinea (men 8.2, women 3.3 per 100,000). |
| Australia & New Zealand | Lip cancer makes up 20.5% of the regional lip/oral/pharyngeal burden, historically over a third of all oral-region cancers in Australia; male ASR 3.2, female 1.1. About 90% arise on the lower lip. |
| Southern & Eastern Europe | Lip cancer represents 12.6% of Southern European and 14.1% of Eastern European lip/oral/pharyngeal cancers; elevated male ASRs in Portugal (3.7), Romania (3.2), Poland, Hungary, Serbia and Moldova. |
| Western Asia & Turkey | 14.3% of the regional lip/oral/pharyngeal burden; high cumulative sun exposure in outdoor work is the common theme. |
| East & South-East Asia | Among the lowest rates in the world (<2.5% of regional lip/oral/pharyngeal cancers), reflecting both less intense UV exposure and differences in skin pigmentation. |
What are the risk factors?
- Cumulative ultraviolet (UV) radiation from sun exposure, especially occupational outdoor work
- Fair skin (Fitzpatrick I–III), light eyes and a history of childhood sunburn
- Actinic cheilitis — a precancerous scaling, fissured condition of the lower lip
- Tobacco smoking and pipe smoking (particularly for mucosal lip lesions)
- Immunosuppression after organ transplantation — risk of lip SCC is markedly increased
- Photosensitising medicines, male sex and age over 60
What are the signs and symptoms?
- A persistent sore, ulcer or crust on the lower lip that does not heal
- A scaly, dry, whitish or thickened patch (actinic cheilitis) with loss of the sharp lip border
- A firm lump or nodule on the vermilion, sometimes bleeding
- Numbness or tingling of the lip or chin (suggesting perineural spread)
- A hard lump under the chin or in the upper neck (nodal metastasis)
- Difficulty moving the lip, drooling or changes in speech in advanced lesions
Two-to-three-week rule: any head or neck symptom that persists beyond two to three weeks should be examined by an ENT specialist with an endoscope — pain is usually a late feature, not an early one.
How is it diagnosed and staged?
- Clinical examination of the whole lip, oral cavity and neck with palpation
- Incisional or excisional biopsy of the suspicious area for histology and depth of invasion
- Ultrasound or contrast CT/MRI of the neck for larger tumours; FNA of suspicious nodes
- Assessment of perineural invasion, bone involvement and tumour thickness in the pathology report
- Dental and sun-damage assessment, including examination for synchronous facial skin cancers
- Sentinel lymph node biopsy consideration for thick or high-risk tumours
Lip cancers are staged within the oral cavity / head and neck cutaneous squamous cell carcinoma systems depending on origin (dry vermilion versus mucosal lip). Tumour size, depth, bone or skin invasion, perineural invasion and nodal metastases determine whether local excision alone is sufficient or neck treatment and adjuvant radiotherapy are required.
What are the treatment options?
- Wide local excision with primary closure for small lesions (often a V or W excision)
- Lip reconstruction with local flaps (Abbe, Estlander, Karapandzic) for larger defects to preserve oral competence, speech and appearance
- Mohs micrographic surgery or curettage/radiotherapy for selected superficial lesions in appropriate settings
- Neck dissection or sentinel node biopsy for thick, recurrent or node-positive disease
- Adjuvant radiotherapy for positive margins, perineural invasion, bone invasion or multiple nodes
- Treatment of actinic cheilitis (topical therapy, laser, vermilionectomy) and field surveillance for new skin cancers
Decisions should be made by a multidisciplinary tumour board, with speech, swallowing and appearance considered alongside cancer control. See how treatment changes with stage →
What is the prognosis?
Small, completely excised lower-lip squamous cell carcinomas have excellent control, with five-year survival commonly reported above 90%. Prognosis falls with large size, deep invasion, perineural spread, mandibular involvement, nodal metastasis and immunosuppression. Recurrence and new UV-related skin cancers are common enough that long-term skin surveillance is standard.
Survival figures are population averages from registry data, not predictions for an individual. See the follow-up schedule →
Can it be prevented?
- Daily broad-spectrum SPF lip balm and reapplication after eating, drinking and swimming
- Wide-brimmed hats and shade for outdoor work; avoid midday sun and tanning beds
- Stop smoking, particularly pipe smoking
- Treat actinic cheilitis early and have persistent lip lesions biopsied
- Regular full-skin and lip checks for organ-transplant recipients and others on immunosuppression
Prevention by region: HPV vaccine, areca nut, tobacco and UV →
Treatment in China for international patients
Lip cancer is uncommon in China compared with Australia or Southern Europe, so the key question for an international patient is whether the treating team routinely performs lip reconstruction. Experienced head and neck and plastic surgery units can combine tumour excision with functional lip repair in one operation.
- Bring the biopsy report and slides, clinical photographs, and imaging of the neck if the lesion is large or recurrent.
- Ask which reconstruction is planned and how oral competence (ability to keep liquids in the mouth), speech and appearance will be preserved.
- If you are immunosuppressed after a transplant, tell the team: it changes surveillance intensity and sometimes the treatment choice.
- Request a written plan for sun protection and field surveillance to continue at home.
Cost guidance: As an illustrative planning range, local excision with lip reconstruction is commonly budgeted at ¥20,000–¥70,000 (about US$2,800–9,800); cases needing neck dissection, flap reconstruction and adjuvant radiotherapy may reach ¥80,000–¥160,000. These are budgeting figures, not a quotation.

Frequently asked questions
What is lip cancer?
Lip cancer is usually a squamous cell carcinoma of the dry red part of the lower lip, caused mainly by cumulative ultraviolet radiation. It is unusually common in Australia, New Zealand, Papua New Guinea and parts of Southern/Eastern Europe among fair-skinned outdoor workers. Small tumours are highly curable with limited surgery that preserves lip function.
Where in the world is lip cancer most common?
Lip Cancer is not evenly distributed: the highest-burden regions are Papua New Guinea & Melanesia, Australia & New Zealand and Southern & Eastern Europe. In 2022 there were about 32,200 new lip cancer cases (C00) worldwide worldwide (male ASR 0.5 and female ASR 0.2 per 100,000; 4.2% of all lip/oral/pharyngeal cancers in 2022), with marked country-to-country variation driven by local exposures such as tobacco, areca nut, oncogenic viruses, ultraviolet radiation and occupational carcinogens.
What are the risk factors for lip cancer?
The main recognised risk factors for lip cancer are cumulative ultraviolet (UV) radiation from sun exposure, especially occupational outdoor work, fair skin (Fitzpatrick I–III), light eyes and a history of childhood sunburn and actinic cheilitis — a precancerous scaling, fissured condition of the lower lip. Risks differ by region: Papua New Guinea & Melanesia has a distinctive exposure pattern, so a patient's country of residence is part of the risk assessment. Having a risk factor does not mean a person will develop cancer.
What are the early signs of lip cancer?
The common early signs are a persistent sore, ulcer or crust on the lower lip that does not heal, a scaly, dry, whitish or thickened patch (actinic cheilitis) with loss of the sharp lip border, a firm lump or nodule on the vermilion, sometimes bleeding and numbness or tingling of the lip or chin (suggesting perineural spread). Head and neck tumours often cause mild, one-sided symptoms that mimic a cold, a dental problem or a sore throat. Any symptom in the head or neck that persists for more than two to three weeks needs an ENT examination rather than repeated antibiotics.
How is lip cancer diagnosed and staged?
Diagnosis requires a tissue biopsy read by a head and neck pathologist, supported by endoscopic examination and contrast CT or MRI of the neck; PET-CT is added when nodal or distant spread is suspected. Staging uses the AJCC TNM system and guides whether surgery, radiotherapy, chemoradiotherapy or systemic therapy is the primary treatment.
What are the treatment options for lip cancer?
Treatment is stage- and site-specific, and usually combines wide local excision with primary closure for small lesions (often a V or W excision), lip reconstruction with local flaps (Abbe, Estlander, Karapandzic) for larger defects to preserve oral competence, speech and appearance and mohs micrographic surgery or curettage/radiotherapy for selected superficial lesions in appropriate settings. Early-stage disease is generally treated with one modality (surgery or radiotherapy), while locally advanced disease needs combined modality treatment planned by a multidisciplinary team.
What is the prognosis for lip cancer?
Small, completely excised lower-lip squamous cell carcinomas have excellent control, with five-year survival commonly reported above 90%. Prognosis falls with large size, deep invasion, perineural spread, mandibular involvement, nodal metastasis and immunosuppression. Recurrence and new UV-related skin cancers are common enough that long-term skin surveillance is standard.
Can lip cancer be prevented?
Many cases are preventable. The most useful steps for lip cancer are daily broad-spectrum SPF lip balm and reapplication after eating, drinking and swimming, wide-brimmed hats and shade for outdoor work; avoid midday sun and tanning beds and stop smoking, particularly pipe smoking. Prevention works best before exposure begins, but stopping tobacco, areca nut and heavy alcohol use still lowers risk after many years of use.
Why does lip cancer almost always affect the lower lip?
The lower lip’s vermilion presents a larger surface directly to overhead sunlight than the upper lip, so it receives a much higher cumulative UV dose. In SEER data roughly 90% of lip cancers arose on the lower lip, and chronic sun exposure in farmers, fishermen, foresters and other outdoor workers is the dominant risk factor.
What is actinic cheilitis and should it be treated?
Actinic cheilitis is chronic UV damage to the lip vermilion: persistent dryness, scaling, fissuring, colour variation and blurring of the lip border. It is considered a precancerous field change and is present in the great majority of lower-lip squamous cell carcinomas, so persistent cases should be assessed and often treated rather than ignored.
Will surgery change the appearance or function of my lip?
Small defects are usually closed directly with little visible change. Larger excisions require local flap reconstruction (for example Abbe, Estlander or Karapandzic flaps) designed to preserve the oral sphincter — the ability to seal the lips for eating, drinking, speech and holding saliva — while restoring a natural contour.
Why is lip cancer so prominent in Australia and New Zealand?
High ambient ultraviolet radiation, a largely fair-skinned population and a history of outdoor work and recreation combine to produce one of the world’s highest lip cancer burdens. Lip cancer represents 20.5% of Australia/New Zealand lip/oral/pharyngeal cancers and historically accounted for over a third of Australian oral-region cancers.
Are transplant recipients at higher risk of lip cancer?
Yes. Long-term immunosuppression substantially increases the risk of cutaneous squamous cell carcinoma, including lip cancer — some series report a roughly twentyfold increase compared with the general population, with risk rising with the dose and duration of agents such as azathioprine.
What does lip cancer surgery cost in China for an international patient?
As a planning range, local excision with lip reconstruction is commonly budgeted at ¥20,000–¥70,000 (about US$2,800–9,800); more advanced cases needing neck dissection, flap reconstruction and adjuvant radiotherapy may reach ¥80,000–¥160,000. These figures are illustrative and not a quotation.
