What is Lip Cancer?

Lip cancer is a malignancy of the lip, predominantly squamous cell carcinoma (90%), with basal cell carcinoma occurring on the cutaneous lip surface and rarely on the vermilion. It is one of the most common malignancies of the oral cavity and is anatomically distinct from intraoral cancers in epidemiology and prognosis.

The lower lip is affected in 90% of cases due to greater sun exposure compared to the upper lip. Lip cancer typically arises on a background of actinic cheilitis, a premalignant lesion characterized by chronic UV damage with dryness, scaling, blurred vermilion border, and leukoplakia. Early detection during the actinic phase or microinvasive stage offers excellent prognosis.

Five-year survival exceeds 90% for early-stage disease but drops significantly with cervical lymph node involvement. Surgical excision and radiation are both effective for primary treatment, with surgery preferred for most cases due to better functional outcomes and the ability to address actinic damage simultaneously.

Symptoms

Persistent ulcer or sore on the lip not healing
Lump, thickening, or hard area on the lip
Crusty, scaly patch on the vermilion border
White patches (leukoplakia) on the lip
Red patches (erythroplakia) — higher malignant risk
Blurred border between vermilion and skin
Bleeding from the lip lesion
Numbness of the lip or chin (mental nerve involvement)
Pain (often late symptom)
Fixed or palpable submandibular/submental lymph node
Cosmetic deformity

Risk Factors

Chronic UV/sun exposure (outdoor occupations, fair skin)
Tobacco use (smoking, especially pipe; chewing tobacco)
Heavy alcohol consumption
Male sex (10-20 fold higher than female)
Fair complexion (Fitzpatrick I-II)
Age over 50
Immunosuppression (transplant recipients)
HPV infection (subset of cases)
Prior actinic cheilitis or oral premalignant lesions
Xeroderma pigmentosum
Albinism
Chronic lip irritation or trauma
Pipe smoking (mechanical and thermal injury)

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Lip lesion or sore not healing within 2-3 weeks
  • Persistent crusting, scaling, or ulceration
  • Lump or thickening of the lip
  • Color changes: white or red patches
  • Numbness in lip or chin
  • Bleeding from a lip lesion
  • Palpable neck or chin lymph node
  • History of significant sun exposure with lip changes
  • Smoker or pipe user with lip changes

Treatment Methods

01
Sun protection: lip balm with SPF 30+, broad-spectrum, daily use
02
Smoking and alcohol cessation
03
Treatment of actinic cheilitis: topical 5-FU, imiquimod, photodynamic therapy, vermilionectomy
04
Biopsy of any suspicious lip lesion
05
Wide local excision with 5-10 mm margins for early invasive cancers
06
V-shaped or W-shaped wedge excision for small tumors
07
Local flap reconstruction (Karapandzic, Abbe-Estlander, Bernard) for moderate defects
08
Free tissue transfer for large defects
09
Radiation therapy: alternative for select small tumors or unresectable cases
10
Vermilionectomy and lip shave: for diffuse actinic cheilitis with carcinoma in situ
11
Elective neck dissection: for tumors over 3 cm or depth over 4-5 mm
12
Therapeutic neck dissection: for clinically positive nodes
13
Adjuvant radiation: positive margins, perineural invasion, advanced T or N stage
14
Mohs micrographic surgery: alternative for select tumors with margin concerns
15
Long-term sun protection and surveillance for new primary cancers
16
Reconstructive considerations: maintaining oral competence, sensation, cosmesis

Anaemia

Dahiliye (İç Hastalıkları)

Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.

Iron Deficiency Anaemia

Dahiliye (İç Hastalıkları)

Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.

Vitamin B12 Deficiency

Dahiliye (İç Hastalıkları)

Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.

Hypertension (High Blood Pressure) Management

Dahiliye (İç Hastalıkları)

Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.

Chronic Kidney Disease

Dahiliye (İç Hastalıkları)

Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.

Hepatitis B (HBV)

Dahiliye (İç Hastalıkları)

Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.

Hepatitis C (HCV)

Dahiliye (İç Hastalıkları)

Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.

Fatty Liver Disease

Dahiliye (İç Hastalıkları)

Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
