Overview of Oral Cancer

Oral cancer refers to cancers that develop in the mouth or the oropharynx (the part of the throat at the back of the mouth). It includes cancers of the lips, tongue, gums, cheeks, floor of the mouth, roof of the mouth, and even parts of the throat. Early detection is crucial for improving outcomes.

Types of Oral Cancer

1. Tongue Cancer: Cancer that develops on the tongue, often starting as a small sore or lump.

2. Lip Cancer: Cancer that affects the lips, commonly caused by sun exposure.

3. Gum Cancer: Cancer of the gums, often detected through unexplained growths or persistent sores.

4. Oropharyngeal Cancer: Cancer that affects the back of the mouth, including the tonsils and the soft palate.

5. Cheek Cancer: Cancer that develops in the inner lining of the cheeks.

6. Mouth Cancer: General term for cancers affecting various parts of the mouth.

Persistent sores or ulcers in the mouth that do not heal.

Pain or tenderness in the mouth or throat.

Difficulty swallowing or chewing.

Unexplained bleeding in the mouth.

Causes of Oral Cancer

• Tobacco Use: Smoking or chewing tobacco is the leading cause.
• Alcohol Consumption: Excessive alcohol increases the risk of oral cancer.
• HPV Infection: Human papillomavirus, particularly HPV-16, is linked to oropharyngeal cancer.
• Sun Exposure: UV radiation from the sun can cause lip cancer.
• Poor Diet: Lack of fruits and vegetables can contribute to cancer risk.
• Weakened Immune System: Certain conditions or medications can suppress the immune system, increasing cancer risk.
• Genetics: Family history may play a role in some cases.

Complications in Oral Cancer

• Spread to Lymph Nodes: Oral cancer can spread to lymph nodes in the neck, complicating treatment.
• Difficulty Eating and Swallowing: Tumors in the mouth or throat can interfere with normal eating and swallowing.
• Nerve Damage: Tumors may affect nerves, leading to pain, numbness, or loss of function.
• Disfigurement: Surgical removal of tumors may result in visible changes or disfigurement in the mouth or face.
• Recurrence: Even after treatment, there is a risk of cancer returning.

Risk Factors of Oral Cancer

• Age: People over 40 are at higher risk.
• Tobacco Use: Smoking and chewing tobacco are major risk factors.
• Alcohol Use: Heavy drinking significantly increases the risk.
• HPV: Infection with certain strains of HPV increases the risk.
• Poor Oral Hygiene: Chronic irritation from poor dental health can lead to increased risk.
• Dietary Deficiencies: A diet low in vitamins A and C increases susceptibility.

Preventions of Oral Cancer

• Avoid Tobacco: Stop smoking and using chewing tobacco.
• Limit Alcohol: Reduce alcohol consumption.
• Healthy Diet: Eat a balanced diet rich in fruits, vegetables, and vitamins.
• Sun Protection: Use lip balm with SPF and avoid excessive sun exposure.
• Regular Dental Check-ups: Visit the dentist regularly for oral cancer screenings.
• Vaccination: Get the HPV vaccine to reduce the risk of oropharyngeal cancer.
• Good Oral Hygiene: Brush and floss regularly to reduce the risk of gum disease and mouth cancer.
