Oral Cancers: Symptoms, Causes, Diagnosis, and Treatment
Oral cancers are a serious health condition affecting the mouth and surrounding areas. They commonly develop on the tongue, lips, gums, inner cheeks, floor of the mouth, or roof of the mouth. Early detection of oral cancers significantly improves treatment success and survival rates.
What Are Oral Cancers?
Oral cancers are a type of head and neck cancer that begin in the tissues of the oral cavity. Most oral cancers are squamous cell carcinomas, originating from the lining of the mouth. These cancers can spread quickly if not diagnosed early, making awareness and regular oral checkups essential.
Causes and Risk Factors of Oral Cancers
Several lifestyle and environmental factors increase the risk of oral cancers, including:
- Tobacco use (smoking cigarettes, bidis, cigars, or chewing tobacco)
- Betel nut and gutka consumption
- Excessive alcohol intake
- Human Papillomavirus (HPV) infection
- Poor oral hygiene
- Ill-fitting dentures causing chronic irritation
- Family history of cancer
- Prolonged sun exposure (lip cancer)
Combining tobacco and alcohol significantly raises the risk.
Early Symptoms of Oral Cancers
Recognizing early symptoms can help in prompt diagnosis. Common signs include:
- Non-healing mouth ulcers
- White or red patches inside the mouth
- Lumps or thickening in the cheek
- Persistent mouth pain
- Difficulty chewing or swallowing
- Loose teeth without obvious cause
- Numbness in the lips or tongue
- Unexplained bleeding in the mouth
Diagnosis of Oral Cancers
Diagnosis involves a thorough clinical examination followed by:
- Oral cavity examination
- Biopsy of suspicious lesions
- Imaging tests such as CT scan, MRI, or PET scan
- Blood tests and HPV testing if indicated
Early-stage oral cancers are easier to treat and have better outcomes.
Treatment Options for Oral Cancers
Surgery
Surgical removal of the cancer is often the first line of treatment. Reconstructive surgery may be required to restore appearance and function.
Radiation Therapy
Radiation therapy is used alone in early stages or combined with surgery and chemotherapy in advanced cases.
Chemotherapy
Chemotherapy helps destroy cancer cells and is commonly used alongside radiation therapy.
Targeted Therapy and Immunotherapy
Advanced treatments that specifically attack cancer cells or strengthen the immune system are increasingly used for selected cases.
A multidisciplinary approach ensures comprehensive care and optimal recovery.
Importance of Early Detection
When oral cancers are detected at an early stage, cure rates are high, and treatment is less extensive. Regular dental checkups, self-examinations, and avoiding tobacco can greatly reduce risk.
Life After Oral Cancer Treatment
Recovery includes speech therapy, nutritional support, and regular follow-ups to monitor for recurrence. With proper care, many patients return to normal daily activities.
