SCC:
I. The great majority of oral and pharyngeal cancers are squamous cell carcinoma (SCC).
2. Oral cancer remains twice as prevalent in males as in females, and nearly twice as many deaths occur in males
As in females. Oral cancer is closely related to increasing age, alcohol consumption and smoking are the main risk Factors.
3. Cancers of the lip and oral cavity account for about two-thirds of all new oral and pharyngeal cancers with
The tongue being the most common site of cancers of the oral cavity.
4. Overall the 5-year survival rate for oral and pharyngeal cancers is about 50%. However, survival rates vary considerably depending on the cancer site, gender, and race. Note:
The 5-year survival rates for cancer of the lip are about 90%, of the tongue. It is about half that and is only about 20% among male African-Americans.
Women tend to have higher survival rates with the exception of cancer of the lip.
5. Erythroplasia, rather than leukoplakia, is often the first sign of cancerous change in a lesion.
