What is Oral Cancer?
Oral cancer is a type of cancer that develops in the mouth, lips, tongue, gums, floor of the mouth, or other oral tissues. The most common type is squamous cell carcinoma (SCC), which arises from the lining of the oral cavity.
Major Risk Factors
- Tobacco Use :- Smoking cigarettes, cigars, or using smokeless tobacco products significantly increases the risk of oral cancer. Tobacco contains harmful chemicals that can damage the cells lining the mouth.
- Alcohol Consumption:- Alcohol is another major risk factor. When combined with tobacco, the risk becomes much higher because alcohol enhances the harmful effects of tobacco on oral tissues.
- Areca Nut and Paan:- Chewing areca nut, paan, gutkha, or betel quid containing tobacco is strongly associated with the development of oral cancer, particularly in South Asian populations.
- Excessive Sun Exposure:- For cancers of the lip, especially the lower lip, prolonged exposure to ultraviolet (UV) rays from sunlight is a major risk factor.
- Human Papillomavirus (HPV):- Certain types of HPV, particularly HPV-16 and HPV-18, have been linked to cancers of the oropharynx and base of the tongue.
Warning Signs of Oral Cancer
Oral cancer may appear as:
- A persistent white patch (leukoplakia)
- A red patch (erythroplakia)
- A mixed red and white lesion (erythroleukoplakia)
- A non-healing ulcer lasting more than two weeks
Any suspicious lesion should be examined by a dentist or healthcare professional promptly.
Common Sites Affected
Oral cancer can occur anywhere in the mouth, but the most commonly affected sites are:
1. Tongue
2. Floor of the mouth
3. Gingiva (gums)
4. Lips
Early diagnosis greatly improves treatment outcomes and survival rates. Regular dental check-ups, avoiding tobacco products, limiting alcohol consumption, and protecting the lips from excessive sun exposure can help reduce the risk of oral cancer.
Remember:- Any oral ulcer, red patch, or white patch that does not heal within two weeks should be evaluated by a dental professional.
