Which Cancerous Structure Would Be MOST Difficult to Successfully Treat

Question

Which cancerous structure would be MOST difficult to successfully treat?
A) Root of tongue
B) Tip of tongue
C) Lesion on upper lip
D) Incisive papilla

Accepted Answer

Because of anatomical location and lymphatic drainage patterns,a cancerous lesion in the root of the tongue is difficult to treat.Cancerous cells from this lesion have only two groups of nodes to filter through prior to reaching the bloodstream.Conversely,a malignant lesion on the tip of the tongue has four levels of lymphatic drainage prior to entering bloodstream.
