ORAL SQUAMOUS CELL CARCINOMA
prognosis of oral squamous cell carcinoma
5 year survival rate

basal cell clinical findings
smooth, raised, shiny, translucent border
depressed center or ulcerated
infiltrative and destructive
t/f basal cell carcinoma occurs in the mouth
FALSE. it does not occur in the mouth
where is basal cell usually
above lip/tragus line due to chronic sun exposure
