Carcinoma of lip
1. Occurs mostly in males
2. Metastases easily
3. Occurs mostly in the lower lip
4. Is mostly basal cell type
Oral Pathology
Answer: 1
Carcinoma of the Lip
Occurs mostly in males: Lip carcinoma, particularly
squamous cell carcinoma, is more common in males than females. This is often
attributed to higher rates of tobacco and alcohol use, as well as increased
sun exposure without protection.
Metastases easily: While lip carcinomas can
metastasize, they do not typically do so as easily as other cancers.
Squamous cell carcinoma of the lip can metastasize, but it is often
localized initially.
Occurs mostly in the lower lip: This is true; the lower
lip is the most common site for lip carcinoma due to greater sun exposure
and thinner skin.
Is mostly basal cell type: This statement is
misleading. While basal cell carcinoma is the most common skin cancer
overall, squamous cell carcinoma is more prevalent in the lip region.
