Key Indications of Mouth Cancer

Difficulty Swallowing And Chewing

Individuals affected by mouth cancer often experience difficulty swallowing and chewing as a result. Oral cancer occurs when the DNA in cells of the tongue, jaw, or mouth tissues become damaged. If this damage causes a mutation in the portion of the DNA responsible for the regulation of cell growth and multiplication, cancer develops. Cancer cells begin rapidly multiplying and colonizing tissues of which they do not belong. When this mechanism occurs in a patient's mouth, on their tongue, or in the tissues of their jaw, it can interrupt the standard mechanical action of voluntary chewing. Swallowing is a mechanism that occurs partly as a voluntary action and partly as an involuntary action. If the oral cancer tumor grows into areas of the back of the mouth, the affected individual may have trouble with both voluntary and involuntary aspects of swallowing food. If the cancerous cells damage or compress the muscles and or nerves that work together to produce these actions, the individual can have trouble carrying out the mechanisms of chewing and swallowing.
