What do hyperplastic (reactive) lesions show in relation to their growth and the stimulus?
There is a direct relation between their growth and that of the stimulus.
Which of the following is NOT a tumor-like hyperplasia mentioned in the lecture?
"Genetically determined white patches of the oral mucosa"
What do neoplastic lesions usually do when the causative stimulus is removed?
"Sustain their excessive abnormal growth."
