Screening (Say Ahhh! See that was easy!...)Adobe Flash Player not installed or older than 9.0.115! 
Screening is quick and painless. It involves just a few minutes of looking in the mouth and throat with a light and feeling the salivary glands, thyroid glands and neck lymph nodes. Any knot or abnormality that lasts more than two weeks calls for a closer examination. For example, a red or white patch on the tongue, a change in the voice or a lump on the neck should be evaluated by a physician or dentist.
