The mouth examination for cancerous or precancerous signs by a medical professional is what is called oral cancer screening. The objective of oral cancer screening is to detect malignancy in the patient’s mouth early to improve chances of a cure.
Oral cancer is something that is often left undetected until it is much too late to change its course and properly treat it. For those that are diagnosed with this detrimental condition, nearly 40% die from the cancer within the first five years.
