Buccal Mucosa (Cheek) Cancer Treatment in Chennai

Buccal Mucosa Cancer Treatment: Cancer Inside the Cheek

Buccal mucosa cancer — cheek cancer, or mouth cancer inside the cheek — starts in the soft lining on the inner surface of the cheeks. Buccal mucosa cancer treatment is mainly surgical: the tumour is removed with a safe margin of healthy tissue, the neck nodes are treated when needed, and the cheek (and jaw, if involved) is rebuilt so that you can open your mouth, chew and speak.

In India this is one of the commonest cancers surgeons see. It is closely tied to chewing tobacco, gutka, paan and areca nut, and it often develops on a background of long-standing white patches or oral submucous fibrosis. Early stage cheek cancer can be cured in most patients; the difficulty is that it is often painless at first and is noticed late.

This page explains how cheek cancer is recognised, why it is so common here, how it is staged, the operations involved, reconstruction choices, when radiotherapy is added, survival figures from Indian data, and what recovery involves.

Early Signs of Cheek Cancer vs an Ordinary Ulcer

An ordinary ulcer from biting the cheek or rubbing on a sharp tooth usually heals within one to two weeks. Cheek cancer does not. See a specialist if any of these persist beyond two weeks:

• A non-healing ulcer: A sore on the inner cheek that keeps returning or slowly grows, often with raised, firm edges.
• A rough or thickened area: A patch that feels hard or warty to the tongue, or a lump within the cheek.
• White or red patches: Leukoplakia (white) or erythroplakia (red) that change in size, colour or texture.
• Restricted mouth opening (trismus): Gradually opening less wide than before. It can mean the tumour has reached the chewing muscles, or that oral submucous fibrosis is present.
• Pain or bleeding: Burning with spicy food, bleeding on touch, or loosening of teeth near the patch, which can mean the gum or jawbone is involved.
• A lump in the neck: A firm swelling under the jaw may be the first sign of spread to the lymph nodes.

Our article on cheek cancer symptoms and stages shows these changes in more detail.

Why Cheek Cancer Is So Common in India

Worldwide, the tongue is the commonest site of mouth cancer. In India it is the buccal mucosa and the neighbouring gum — together called the gingivobuccal complex. The reason is where people hold tobacco: a quid of betel leaf, areca nut, khaini or gutka is kept against the inner cheek for hours, exposing the lining to carcinogens day after day.

The scale is large. India accounts for about a third of the world's oral cancers, and according to the Global Adult Tobacco Survey (GATS-2, 2016–17), 21.4% of Indian adults use smokeless tobacco. Our guide to gutka and pan masala risk explains how these products damage the mouth.

Many patients also have oral submucous fibrosis (OSMF), a stiffening of the cheek lining caused by areca nut. OSMF restricts mouth opening and is itself a pre-cancerous condition. Stopping all tobacco and areca nut — before and after treatment — is one of the most important things you can do to reduce the risk of a new cancer.

Pre-Cancer in the Cheek: White Patches, Red Patches and OSMF

Most cheek cancers do not appear out of nowhere. They are often preceded for months or years by changes in the lining that doctors call oral potentially malignant disorders. Recognising and treating these is the best chance of preventing cancer altogether.

• Leukoplakia: A white patch that cannot be wiped off and has no other obvious cause. Most never become cancer, but pooled studies suggest roughly 6–7% eventually do, and the risk is higher for patches that are thick, speckled or growing.
• Erythroplakia: A red, velvety patch. It is less common than leukoplakia but far more likely to contain severe dysplasia or early cancer, so it should always be biopsied.
• Oral submucous fibrosis: Progressive stiffness and pale, leathery bands in the cheek from areca nut use. Studies following patients over years report malignant change in roughly 4–6%.

A biopsy shows whether a patch has dysplasia (abnormal but not yet cancerous cells) and how severe it is. Mild changes may be watched closely after stopping tobacco; more severe changes or suspicious areas are usually removed. If a patch has already turned into cancer, finding it at this stage often means a smaller operation and a much better outlook.

How Buccal Mucosa Cancer Is Diagnosed and Staged

Diagnosis begins with an examination of the cheek, gums, jaw and neck, checking how deep the lump extends, whether it is fixed to bone, and how wide the mouth opens. A biopsy taken under local anaesthetic confirms the diagnosis and grade.

Scans then map the extent. A contrast CT (CECT) is particularly good at showing whether the jawbone is eroded; MRI shows spread into soft tissues and the chewing muscles. Larger tumours may need a chest scan or PET-CT. Staging follows the AJCC 8th edition TNM system: the tumour's size and depth of invasion, lymph node spread and any distant spread combine into stages I to IV.

Bone involvement is the key surgical question in cheek cancer. Tumours that sit close to the gum often reach the jaw, and that decides whether a rim of bone or a full segment needs to be removed.

Buccal Mucosa Cancer Surgery: Excision, Jaw Surgery and Neck Dissection

Surgery is the main treatment. The aim is complete removal with clear margins in every direction — through the cheek, towards the skin, and down to bone — while preserving mouth opening and appearance as far as possible.

• Wide local excision: The tumour is removed with a cuff of normal tissue, with margins checked by frozen section during the operation. See wide local excision.
• Marginal mandibulectomy: When the tumour touches but has not deeply invaded the jaw, a rim of bone is removed while keeping the lower jaw continuous.
• Segmental mandibulectomy: When the cancer has grown into the bone, a full section of the jaw is removed and must be rebuilt. Our mandibulectomy page explains both types.
• Composite resection: For advanced tumours, cheek, jaw and neck tissues are removed together in one block — sometimes called a commando operation. See composite resection.

A neck dissection is usually performed at the same operation. Cheek cancers can spread to the neck lymph nodes before they can be felt, and a Tata Memorial Centre trial showed that treating the neck early in node-negative oral cancer improves survival.

Reconstruction: PMMC Flap vs Free Flap

Removing a cheek cancer leaves a gap in the lining of the mouth, sometimes extending through to the skin or including part of the jaw. Rebuilding it stops the mouth scarring shut and restores chewing, speech and facial contour.

• PMMC flap: The PMMC flap (pectoralis major myocutaneous flap) uses chest muscle and skin, swung up to the cheek on its own blood supply. It is reliable and robust and does not need microvascular surgery, which makes it valuable for medically frail patients and some salvage situations.
• Free flap: In free flap reconstruction, thin tissue from the forearm or thigh — or bone from the leg (fibula) when the jaw has been removed — is transferred and connected to neck vessels under a microscope. This is performed with our reconstructive colleague and usually gives a thinner, more flexible lining and a better jaw shape.

Which option suits you depends on the size of the defect, whether bone is missing, your general health and any previous treatment. Our comparison of free flap vs PMMC goes through the trade-offs.

When Radiotherapy Is Added After Surgery

The final histopathology report on the removed tissue guides what happens next. Our explanation of the oral cancer histopathology report covers each term.

• Clear margins and no adverse features: Often no further treatment beyond close follow-up — for example a small tumour with margins over 5 mm and no nodal spread.
• Close margins or other risk features: Postoperative radiotherapy is usually recommended for margins of 1–5 mm, nerve or vessel invasion, pT3–T4 tumours or involved nodes.
• Positive margins or extranodal extension: Radiotherapy combined with chemotherapy (chemoradiation). A margin under 1 mm is treated as positive.

Radiotherapy should ideally start within about six weeks of surgery. Because the cheek lies close to the teeth and jaw, a dental assessment beforehand is important to reduce the risk of jaw-bone damage later — see dental treatment before radiotherapy.

Buccal Mucosa Cancer Survival by Stage

Indian data is the most useful reference. In Tata Memorial Centre data on 1,895 patients with oral cavity cancer treated in 2016, about 66% of patients with buccal mucosa cancer were alive at five years. Across all oral cavity cancers in that group, five-year survival was about 83% for stage I and about 55% for stage IV.

The biggest influences on outcome are the stage at diagnosis, whether lymph nodes are involved, whether clear margins are achieved, and whether the person stops tobacco. Cheek cancer found as a small ulcer has a very different outlook from one found after the mouth has stopped opening — which is why a persistent patch should never be watched for months.

Cancer of the gum behaves similarly and is often treated alongside cheek cancer; see our guide to gum cancer for that site specifically.

Recovery and Mouth-Opening Exercises

After major surgery with reconstruction, most patients stay in hospital about one to two weeks. A feeding tube supports nutrition while the mouth heals, and a temporary tracheostomy may be used for a few days if swelling is expected.

Keeping the mouth open is the central goal of rehabilitation. Scar tissue and radiotherapy both tend to tighten the cheek, so daily stretching exercises begin as soon as the wound allows — using stacked tongue depressors or a jaw-stretching device — and continue for months. Speech and swallowing therapy, dietary advice and dental rehabilitation follow.

Teeth near the cancer may have to be removed, and losing part of the jaw affects how dentures fit. Once healing is complete, dental rehabilitation — a prosthesis, or in selected patients implants placed in a reconstructed jaw — helps restore chewing. This is planned with your surgical team, because bone that has received radiotherapy needs particular care.

Follow-up is frequent in the first two years, when recurrence is most likely, and continues long term to watch for a new cancer elsewhere in the mouth. Report any new ulcer, lump, pain or reduction in mouth opening between visits rather than waiting for the next appointment.

Questions to Ask Before Cheek Cancer Surgery

A clear conversation before surgery helps you and your family know what to expect. Useful questions include:

• Stage and spread: What stage is my cancer, and is the jawbone or are the neck nodes involved?
• Extent of surgery: Will part of my jaw be removed, and will both sides of the neck be treated?
• Reconstruction: Which flap do you recommend for me, and why?
• After surgery: Will I need a feeding tube or tracheostomy, and for how long?
• Further treatment: How likely is radiotherapy, and when would it start?
• Long term: How will my mouth opening, speech and appearance be affected, and what exercises will I need?

Bringing your biopsy report, scans and a list of your medicines to the first visit makes these answers much more specific.

What Affects the Cost of Buccal Mucosa Cancer Treatment

Cost varies with the extent of treatment. The main factors are:

• Size of resection: A wide local excision alone versus a composite resection.
• Jaw involvement: Whether a marginal or segmental mandibulectomy is required.
• Reconstruction: Direct closure, a PMMC flap or a microvascular free flap, including bone flaps.
• Neck dissection and hospital stay: One or both sides of the neck, and the number of days in hospital and intensive care.
• Further treatment: Whether radiotherapy or chemoradiation is needed.
