Buccal Mucosa Cancer
Buccal mucosa cancer is a type of oral cancer that affects the inner lining of the cheek. Symptoms may include persistent mouth ulcers, swelling, pain, or difficulty chewing and swallowing. Diagnosis and treatment planning depend on clinical examination, biopsy findings and the stage of the disease.
Overview
Dr. Satish Rao is a surgical oncologist in Mumbai. This page explains buccal mucosa cancer symptoms, risk factors and diagnosis. Call to book an appointment.
What Is Buccal Mucosa Cancer?
The buccal mucosa is the moist lining of the inner cheek, the tissue your tongue touches when you run it along the inside of your mouth. When cells here are exposed to repeated damage from tobacco or betel quid, they can begin to multiply abnormally. The resulting tumour is most often a squamous cell carcinoma. Left untreated, it can invade the cheek muscle, reach the jawbone, and spread to lymph nodes in the neck.
What Are the Symptoms of Buccal Mucosa Cancer?
A painless or non-healing ulcer inside the cheek lasting more than 7-10 days is an important early sign.
Symptoms to watch for include:
- 1. A persistent sore or ulcer on the inner cheek that does not heal in 7-10 days
- 2. A painless lesion or thickening in the cheek wall
- 3. White patches (leukoplakia) or red patches (erythroplakia) on the inner cheek
- 4. Difficulty opening the mouth fully (trismus)
- 5. Slight bleeding from the cheek lining without a clear cause
- 6. Swollen, painless nodes or lumps in the neck lasting more than 7-10 days
Any lesion inside the mouth that has not resolved within 7-10 days warrants specialist evaluation. Early lesions may be painless.
What Are the Causes and Risk Factors?
Key risk factors include:
Tobacco (smoked and smokeless)
Gutkha, khaini, and zarda held against the cheek cause sustained DNA damage to the mucosal lining.
Betel quid and areca nut
Arecoline in areca nut is independently carcinogenic and the primary driver of oral submucous fibrosis, a recognised precancerous condition.
Alcohol
Acts as a solvent that amplifies the carcinogenic effect of tobacco; the combination multiplies risk.
HPV infection:
High-risk strains HPV-16 and HPV-18 are an established contributory factor in some oral cavity cancers.
Chronic irritation and poor oral hygiene:
Sharp teeth, ill-fitting dentures, and untreated gum disease create a mucosal environment that facilitates abnormal cell growth.
Unhealthy Diet
A diet lacking essential vitamins and nutrients, especially fruits and vegetables, may contribute to a higher cancer risk.
How Is Buccal Mucosa Cancer Diagnosed?
Diagnosis requires clinical examination, imaging, and tissue confirmation. No single test is sufficient on its own.
Clinical examination
Visual inspection and palpation of the inner cheek, palate, floor of mouth, and neck lymph nodes
Biopsy
A small tissue sample taken under local anaesthesia, the definitive step to confirm malignancy and tumour type
CT and MRI
CT assesses bone involvement and lymph nodes; MRI defines soft-tissue depth and perineural spread
PET-CT
Detects distant metastases and guides staging
Risks and Limitations
- A persistent sore or ulcer on the inner cheek that does not heal in 7-10 days
- Depending on the extent of surgery, speech, chewing, swallowing, or mouth opening may be affected.
- Reconstruction, where needed, may involve additional procedures and a wound at the donor site.
- Anaesthesia carries its own risks, which depend on the person’s overall health.
- Radiation therapy can cause mouth soreness, dry mouth, skin changes, and difficulty swallowing.
- Further treatment may be needed depending on the stage of the disease and the findings after surgery.
Factors That Influence Prognosis
Stage at diagnosis, surgical margin status, and lymph node involvement are the main factors considered when planning treatment and discussing prognosis. Each patient’s situation is different and is assessed individually.
Frequently Asked Questions
How is buccal mucosa cancer treated?
Treatment centres on surgery, often combined with radiation therapy, and is planned by a multidisciplinary team. Early-stage cancers are treated surgically with clear margins. In advanced stages, a combination of surgery, radiation, and systemic therapy may be used.
How long does recovery after surgery take?
Recovery time depends on the extent of surgery and on whether reconstruction, such as free flap reconstruction, is needed.
Can buccal mucosa cancer recur?
Recurrence can occur after treatment, which is why structured follow-up is essential. Any new sore, lump, or change in mouth opening after completing treatment should be reported to the treating team promptly.
When should a mouth ulcer be evaluated?
Any lesion inside the mouth that has not resolved within 7-10 days warrants specialist evaluation.
What should I bring to my first consultation?
Please bring any prior reports, scans, and prescriptions, along with a list of your current medications.
