What is the difference between laryngitis and a larynx cancer?

Need an examination: Laryngitis= inflammation of the voice/vocal cords larynx cancer= malignant tumor of the voice box both will make the voice change (hoarse, short of breath, painful or difficult speaking), and only an ent/head and neck surgeon can help you tell the difference between the two. The doctor will slide a slender camers into your nose/mouth and look at the throat. If you smoke, stop immediately...
