What Is Oral Cancer?

Oral cancer is a type of cancer that develops in the tissues of the mouth or oral cavity. It can affect the lips, tongue, cheeks, gums, floor of the mouth, hard palate, soft palate, or the area behind the wisdom teeth. The most common type is oral squamous cell carcinoma, which begins in the thin, flat cells lining the mouth.

When detected early, oral cancer has a significantly better chance of successful treatment. Regular dental check-ups play a vital role in early detection because dentists are often the first healthcare professionals to identify suspicious oral lesions.

At Singh Dental Care, every comprehensive dental examination includes an oral cancer screening to detect suspicious changes as early as possible.

Signs and Symptoms :- Early oral cancer may be painless, making routine dental examinations extremely important.

Common signs and symptoms include:

• A mouth ulcer that does not heal within two weeks

• Red patches (Erythroplakia)

• White patches (Leukoplakia)

• Red and white mixed patches

• Persistent pain or soreness in the mouth

• A lump or thickened area inside the mouth

• Difficulty chewing or swallowing

• Persistent sore throat

• Difficulty moving the tongue or jaw

• Loose teeth without an obvious cause

• Numbness of the lips, tongue or mouth

• Unexplained bleeding from the mouth

• Persistent bad breath

• Voice changes

• Ear pain without an ear infection

• Swelling in the neck due to enlarged lymph nodes

Causes of Oral Cancer :- Oral cancer develops due to abnormal growth of cells, often influenced by several risk factors.

• Tobacco Use :- Smoking cigarettes, cigars, pipes and using smokeless tobacco significantly increase the risk.

• Alcohol Consumption :- Heavy alcohol use substantially increases the risk, especially when combined with tobacco.

• Human Papillomavirus (HPV) :- Certain strains of HPV, particularly HPV-16, are associated with cancers affecting the mouth and throat.

• Betel Nut (Areca Nut) and Gutka :- Chewing betel nut, gutka, paan, khaini or similar products is a major risk factor, especially in South Asian countries.

• Excessive Sun Exposure :- Prolonged sun exposure increases the risk of lip cancer.

• Poor Nutrition :- A diet lacking fruits and vegetables may contribute to increased risk.

• Chronic Irritation :- Although chronic irritation alone does not directly cause oral cancer, it may contribute alongside other risk factors.

• Weakened Immune System :- Individuals with reduced immunity may have an increased risk.

Risk Factors

• Smoke or use tobacco products

• Consume alcohol heavily

• Chew gutka, paan, betel nut, or areca nut

• Have HPV infection

• Are over 40 years of age

• Have prolonged sun exposure affecting the lips

• Have a family history of cancer

• Have poor oral hygiene combined with other risk factors

• Have a previous history of oral cancer

Types of Oral Cancer :- Depending on the area involved, oral cancer may occur in:

• Lip Cancer :- Usually affects the lower lip and is often related to tobacco use or sun exposure.

• Tongue Cancer :- One of the most common forms of oral cancer.

• Buccal Mucosa Cancer :- Occurs on the inner lining of the cheeks and is frequently associated with tobacco and betel nut chewing.

• Floor of Mouth Cancer :- Develops beneath the tongue.

• Gum (Gingival) Cancer :- Affects the gums surrounding the teeth.

• Palatal Cancer :- Occurs on the roof of the mouth.

What Happens If Oral Cancer Is Left Untreated?

Without treatment, oral cancer can:

• Grow deeper into surrounding tissues

• Spread to nearby lymph nodes

• Invade the jawbone

• Affect speech and swallowing

• Spread to other parts of the body (metastasis)

• Become life-threatening

Early diagnosis greatly improves treatment success and survival

Diagnosis at Singh Dental Care :- Our dental team performs a comprehensive oral cancer screening during routine examinations.

• Clinical Oral Examination :- Careful inspection of the lips, tongue, cheeks, gums, palate, and floor of the mouth.

• Neck Examination :- Assessment of lymph nodes for swelling or enlargement.

• Medical and Lifestyle History :- Evaluation of tobacco use, alcohol consumption, betel nut chewing, HPV risk factors, and family history.

• Special Screening Tests : In selected cases, additional oral cancer screening aids may be recommended.

• Biopsy Referral :- If a suspicious lesion is identified, referral for a biopsy is essential to confirm the diagnosis.

• Imaging Studies :- CT scans, MRI, ultrasound, or PET scans may be recommended by specialists to determine the extent of disease.

Treatment Options :- Treatment depends on the stage, location, and extent of the cancer.

• Surgical Removal :- The primary treatment for many oral cancers involves removing the cancerous tissue.

• Radiation Therapy :- High-energy radiation destroys cancer cells and may be used alone or after surgery.

• Chemotherapy :- Cancer-killing medications may be recommended for advanced disease or combined with radiation therapy.

• Targeted Therapy :- Certain medications specifically target cancer cells while minimizing damage to healthy tissue.

• Immunotherapy :- Some advanced oral cancers may be treated using medications that help the immune system fight cancer.

• Rehabilitation :- Speech therapy, swallowing therapy, nutritional support, and reconstructive surgery may be necessary after treatment.

Prevention Tips

Although not all cases are preventable, you can significantly reduce your risk by:

• Avoiding all forms of tobacco

• Avoiding gutka, paan, betel nut and areca nut products

• Limiting alcohol consumption

• Maintaining good oral hygiene

• Eating a balanced diet rich in fruits and vegetables
